1.0 Chair’s Report – J. Edward Smith 1.1 IEEE PES Upcoming Meetings 2011 Power Systems

March 20 – 23, 2011 Phoenix, Arizona PES General Meeting July 2011 Detroit, Michigan

1.2 2010 PES General Meeting Minneapolis, Minnesota

1.2.1 PES Technical Council Activities

1.2.1.1 The Technical Committees (i.e. Transformers Committee) should have and/or appoint a representative on the PES Coordinating Committee. The representative should attend the Coordinating Committee meeting at each General Meeting. 1.2.1.2 The Transformers Committee should make contact with Mr. Michael Lindsay, PES General Council. Mr. Lindsay gave a presentation on ”Understanding Your Disclosure Obligation” that applies to potential issues we are having within the Transformers Committee. It would be a good idea to make contact with him to probe the possibilities of delivering his presentation to the Transformers Committee. I will make contact with him prior the San Diego meeting to explore the possibilities. A couple of key points within his presentation that apply to our group would be, first, Consultant and their affiliation should be disclosed on the roster when it's circulated. Second, all rosters MUST have the employer disclosed and the affiliation disclosed. There should be separate columns for both. 1.2.2 PES Technical Council Technical Sessions Committee 1.2.2.1 Future General Meetings 2011 Detroit 2012 San Diego 1.2.2.2 2010 PES General Meeting Paper Presentations

1040 Papers Accepted (Panel & Conference) 220 Papers Rejected Acceptance rate for papers is 80%+ 1.2.2.3 Primary concerns with papers, reviewing and presenting!

Consistency of paper reviews based on foreign authors understanding and use of the English language. Same concern with paper presentation when the presenter has poor communication skills based and clear English.

Commercialism of papers not just obvious commercial issues i.e. Talking about the quality of a product or comparing one product to another.

The technical content of papers that represent original content and not previously published content. PES now has a program that they run papers through that will identify the % of the paper that has been previously published.

Subjectivity of paper reviews reviewer to reviewer. There needs to be more specific guidelines for the review process. Send notes or comments to [email protected] 1.2.2.4 Meetings and Marketing Committee (M&M Committee) Rick Taylor still pushing joint Technical Committee meetings. He has changed his focus to have the smaller Technical Committee’s "piggyback" on the location and meeting of one of the larger Technical Committee's. He used Transformers and Switchgear as examples. Technical Sessions TCPC and M&M Committee are separate. Marketing vs. paper session review and scheduling. Should this be a Subcommittee within the Technical Committees? The representative for each of these could the same person or different. NOTE: The TCPC chair should be a position within the Technical Council that is fixed (6 years min) and not a part of the Vice Chairs responsibility during his tender as Vice Chair (2 years). Experience in this position is very valuable. We need to review Technical Editors position vs. TCPC position. There appears to be some overlap here. 1.2.2.5 2011 PES General Meeting, Detroit, Michigan

2011 SUPER SESSIONS Electric Vehicles Mike Hittel, Chair Smart Grid Edwin Liu, Chair Wind Power & PV Tom McDermont, Chair Energy Storage Ali Nourai, Chair Energy & Environment Kevin Taylor, Chair The IEEE PES is looking at hosting a reception on Monday evening (like the Transformers Committee on Sunday). Therefore it was recommended that the poster session be moved to Wednesday afternoon.

Starting at this meeting if a presenter does not show up to present his or her paper or poster will not be posted on the web site and the subject will be returned to the author. 1.2.2.6 General Comments

There will be a TCPC meeting in January in conjunction with the JTCM meeting in Atlanta. The paper presentation schedule should be finalized at this meeting. All the meetings should be finalized and plugged into this schedule prior to this meeting.

mailto:[email protected]

There is a need for a meeting of the Technical Committee members, Meetings and Planning Chairs. This interaction and sharing of information is one of the things that is driving the push for Joint Technical Committee Meetings. It is not the intent to force the JTCM on the Technical Committees. It was specifically pointed out that this was strictly at the Technical Committee's discretion. Do we have a candidate to nominate for Technical Program Chair for the 2012 General Meeting in San Diego? Just a thought! Let me know if you have a recommendation. The PES now wants to capture all the Panel Session Power Point presentations to be posted to the web site. It is the responsibility of the author to upload it in .pdf format. Super Sessions will also apply for this requirement. Super Sessions will also be videoed and posted on the PES website. They may also choose to do a voice over Power Point presentation Paper Sessions vs. Paper Forums appears to be a lesser priority and at the desertion of the TCPC Chair of each Technical Committee depending on the number of papers that the Technical Committee must schedule for presentation. Main topic for the January TCPC meeting must be to discuss how we improve the acceptance criteria for papers, thereby improving the quality of papers. Let me know if you have suggestions for this. 1.2.3 PES Technical Council O & P Committee Credit was give to the Transformers Committee at the start of the meeting as being the only Technical Committee within the PES with an approved O&P manual. Approved at the 2010 General Meeting in Minneapolis (with much frustration) Transmission & Distribution Technical Committee Technical Committees O&P manuals submitted for review on 7/11/2010 Switchgear Committee (approved at the GM 7/27/2010) Insulated Conductors (approved at the GM 7/27/2010) Stationary Battery (approved at the GM 7/27/2010) Nuclear Power Engineering (approved at the GM 7/27/2010) Energy Development & Power Generation (approved at the GM 7/27/2010)

NOTE: "(approved at the GM 7/27/2010)" means that it was approved by the Technical Council O & P Committee. It must then go to and be approved by AUDCOM. AUDCOM will review each O&P Manual to make sure it matches the baseline document or at least it falls into the "in the spirit of" of matching the baseline document. Submitted for review after the 7/11/2010 date Surge Protection Devices Power Systems Instrumentation & Measurements Power Systems Relaying

No document submitted to date Electric machinery Power Systems Analysis, Computing and Economics Power Systems Communication Substations All other TC's do not develop standards and are not required to have a O&P or P&P manuals. The deadline FOR APPROVAL for all TC's O&P manuals is 10/18/2010 The Transformers Committee’s manual has been sent to all TC's to be used as a template for all others to follow. The Administrative Subcommittee of each Technical Committee is solely responsible for approval of their P&P Manual. The primary guideline for approval is that it follows the guidelines in the TC's O&P Manual. Two classifications of WG members "voting" and "non voting". Non voting members are not included in establishing a quorum. Voting vs. non voting membership is at the discretion of the WG Chair. The Transformers Committee is the only TC with an approved P&P. The Technical Council now wants to use our P&P as a template for all other TC's. We need to send a copy to the Technical Council Secretary Jeff Nelson. Next meeting is the second week of January at the Joint Technical Committee Meeting in Atlanta. 1.2.4 2010 IEEE PES General Meeting Presidents Remarks

PES Technical Council Meeting July 2010 SummaryMr. Michael Lindsay IEEE Standards Legal Council, gave a presentation on 'Understanding YourDisclosure Obligation”A couple of key points within his presentation that apply to our group would be:

Consultants and their affiliation should be disclosed on the roster when it's circulated. Second, all rosters MUST have the employer disclosed and the affiliation disclosed. There should

be separate columns for both. AMS will address this issue.Can he make a presentation to us at our next meeting? Matt and Ed will investigate. Prevost asked-who would cover the costs of having Mr. Lindsay attend the spring meeting? Matt Ceglia may be able tocover this information.

Papers at General MeetingsPrimary concerns with papers, reviewing and presenting! Over 1040 papers accepted, most werepresented.Consistency of paper reviews based on foreign authors understanding and use of the English language.Same concern with paper presentation when the presenter has poor communication skills based and clearEnglish.Commercialism of papers: Must be aware of talking about the quality of products, or comparing products.Content of papers to identify new content, vs. previously published. PES has a program that examines thedocument and compares to previous papers for original content.Being more consistent in our reviews of papers. PES is looking for more consistency in the reviews, sowill need better guidelines to give to the reviewers.

The TCPC chair should be a position within the Technical Council that is fixed (6 years min) and not apart of the Vice Chairs responsibility during his tenure as Vice Chair (2 years). Experience in this positionis very valuable. We (Trnsf Comm) need to review Technical Editors position vs. TCPC position. Thereappears to be some overlap here. The next meeting will be in Jan 2011.

Do we have a candidate to nominate for Technical Program Chair for the 2012 General Meeting in SanDiego?

Members -- Discussion of guidelines for reviewing of papers. General guidelines are provided in theauthors kit, and there is also a Reviewer and Editor guideline Can we get better presentation ofsubstance, not just a note that something was done.

PES Technical Council O&P ManualCredit was give to the Transformers Committee at the start of the meeting as being the only TechnicalCommittee within the PES with an approved O&P manual. They acknowledged Peter Balma for his workto complete this. The O&P was approved at the 2010 General Meeting in Minneapolis.

WG P&P manuals- Adcom is responsible for review and approval of their own P&P manual. TrnsfComm P&P is the only approved document, and it was offered to others as an example.


Jim Smith has resigned as Instrument Subcommittee Chair. Ross McTaggart will be the new

chair.

Lundquist: Does AMS fulfill needs to disclose affiliation? Clarification: What is the affiliation of aperson? If a consultant is representing another sponsoring company, participating, and voting on theirbehalf, that affiliation must be disclosed.

3.5 Vice Chair’s Report – Bill Chiu

The full report is available. Refer to Section 4.0 - Vice Chair’s Report for further details.

Call for papers for PES general meeting is in progress.Papers to be reviewed and authors notified by the end of Feb.2011.2010 PES meeting 15 submitted, 13 approved, 2 author no-shows. Authors, who do not show up, willnot have their papers published.

** Note: This application does not have a Subcommittee Sponsor. The application wassponsored by Power Transformer Subcommittee during the discussion, and then approved.

These applications were reviewed at the Fall 2010 Administrative Subcommittee meeting. Allapplications were approved.

The Committee welcomes and encourages active participants to become Members of theCommittee. Requirements and application forms can be found in the Organization andProcedures (O&P) Manual, accessible on the Committee website. Subcommittee Chairs areencouraged to recommend new members, and to communicate the process of attainingmembership through active participation and contribution in Committee work at the WG andSC level. WG and SC Chairs are reminded also that signing an application sponsoring a newmember signifies their sponsorship that the applicant has met the requirement of membershipand active participation for at least one year in the WG or SC they Chair. New memberapplications may be submitted to the Committee Secretary’s attention at any time. Applicationswill be collected for review and approval in batches at each Administrative Subcommittee


meeting. For an application to be reviewed at the next meeting, the application will need to bereceived by the Committee Secretary a minimum of one week prior to the start of the thatmeeting.

Committee, Subcommittees, and Working Group Rosters

In order to provide indemnification to working group and subcommittee members it is crucial thatmembership lists be maintained. Our AM system has these functions built-in to ease theseadministration tasks. It is important that each subcommittee and working group chair keep therosters updated so that this information can be provided to the IEEE SA.

A similar main committee roster has also been developed to track attendance for the MainCommittee meeting on Thursdays. The data will be used to update participant’s membershipprofile.

Meeting Minutes

The minutes of the Houston, TX Spring, 2010 Transformers Committee meeting were posted tothe committee website on October 10, 2010.

Subcommittee Chairs are requested to submit their SC Minutes for the Toronto, ON meeting byDecember 15, 2010. The minutes should be submitted via e-mail to the Committee Secretary[[email protected]], with a copy to Susan McNelly [[email protected]] for posting on theCommittee website. The submittal should be formatted in Word 2007 (or earlier versions) andshould be formatted similar to this report, and as shown in the present assembled Minutes, withnumbering as indicated in the Main Committee Meeting Agenda. Please indicate total attendancecount for each Subcommittee, Working Group, and Task Force meeting in your Minutes. Pleasedo not send a copy of the attendance listing for this attendance count. If a SC Vice-Chair,Secretary, or other SC member is preparing the SC Minutes, please advise them of these detailsregarding the Minutes submittals.

Please do all you can to get the minutes in as soon as possible. Collecting the minutes fromeach subcommittee is the most difficult and time consuming part of this job. Your full corporationand support in this matter is greatly appreciated.

He wants to find ways to spend the additional funds, not to reduce income.Motion new first time ‘user’ attendees, or ‘users’ who have not attended in the past 5 years, will get freebase registration. Motion Anderson, Second Bartley It will be published and distributed by emailnotice to interested individuals.Discussion of previous attempt at Bring a buddy – did the participants follow-up and continue to attend?Motion passed We will start the new policy, as a pilot program, to be reviewed at our next meeting.

The group has previously sponsored the Standards (Monday) lunch for activity chairs Subcommittee,WG, and TF chairs. We should instate this as policy.Motion: Chiu Second: Bartley Motion passed.


3.7A Awards Report Tom Prevost

Some awards requests may have been missed.Motion: Prevost; Past Committee Members will get their recognition certificates by mail, not in person.Second: Chiu. Motion passed.Formal report to be issued later.

When does a task force chair get an award? A committee award should be made available. In the case ofa TF that made a standard, it should have been designated as a WG. It should be treated as such, and willbe by the Standards board.

3.8 Meeting Arrangements, Host Report– Greg Anderson

Gate crashers, those that are not registered and have no name badge. Some active WG leaders have beenviolators in the past. Now we have a Zero Tolerance policy. No registration-- you cannot attend.AMS system review. Need enhancements and different more useful reports. Asking for ability toproduce intelligent name badges. They may offer Twitter links?The tutorial presentations are currently a problem. We need a new coordinator. We have a limitedbacklog of available presentations.

3.9 Standards Report – B. Bartley

Bill Bartley discussed the highlights of the draft report of standards activities since the March, 2010Meeting (Houston, TX).

Presently have 100 documents, and 50 active PARS. Many documents will expire at the end of the year,if we do not act.

Bill Bartley reiterated that a PAR for revision will extend the life of the standard for 4more years. Adocument will not be approved for reaffirmation by RevCom if there is a technical error. It must beresolved. No changes of any kind will be allowed in a reaffirmation. So if there is a technical error thatsomeone will point out, then it should be revised.

Subcommittee Chairs asked to review Standards Database to ensure that the information provided iscorrect.

Further details of the standards activities are listed in the Standards Report and it is included in theAppendix C - Transformer Standards Development Status and Transformer Committee OrganizationalChart.

Page 1 of 4

1. Opening Remarks

•••• Following welcoming and introductions, Chair, William Bartley summarized the recent activities of the Transformer Standards activity for the seven-month period of Mar to Oct 2010. The Transformer Committee is responsible for almost 100 standards, plus over 40 PARs (projects for new standards and revisions). In the last seven months, one new Standard, eight Revisions and four Reaffirmations were approved by RevCom. In this same period, NesCom approved two PARs for new standards, ten PARs for Revisions, five PAR modifications, and one PAR extension. For the full STANDARDS REPORT see the TC website (The link is: http://www.transformerscommittee.org/meetings/F2010-Toronto/Minutes/F10-StandardsReport.pdf ).

•••• The IEEE TC requirements to have quorum present was reiterated.

2. Meeting Attendance The Standards Subcommittee met on Wednesday, Oct 27, 2010, at 4:30 PM. A role call showed 28 members in attendance constituting a quorum. Over all 81 attended with, 53 quests including 7 that requested membership.

3. Approval of previous meeting minutes

The Chair asked if there were any comments or corrections to the previous meeting minutes, and motioned for approval. There where no comments to the meeting minutes from the Spring 2010 meeting in Houston, Texas and minutes were approved.

As approval could not be obtained due to lack of quorum at Spring 2010 meeting in Houston, Texas; the Chair then asked if there were any comments or corrections to the Fall 2009 meeting in Miami, Florida meeting minutes and motioned for approval. There where no comments to meeting minutes and The Fall 2009 meeting minutes in Miami, Florida were approved.

4. Working group reports.

•••• Cont. Revision of C57.12.00 – Steve Synder reported the following:

C57.12.00-2010 was published on September 10, 2010, concluding a two-year long ballot process. This is a revision of C57.12.00-2006.

There were a total of 16 comments/issues where we indicated "would be carried forward for future consideration". These break down as follows:

(a) 7 issues to C57.12.00 Performance Characteristics Continuous Revisions Working Group (b) 5 issues to Dielectric Tests Subcommittee (c) 1 issue to Distribution Transformers Subcommittee (d) 1 issue to Insulating Fluids Subcommittee (e) 2 issues to be deleted - they were addressed in the current revision.

The C57.12.00 standards chair will be sending these comments to the various subcommittee chairs for their action.

There are several WG's and TF's in various subcommittees which are working on changes that may go in this document. As new material is made available, it will be collected until there is enough to warrant another revision. This is typically at least two (2) years.

Once the anticipated schedule is determined, the WG Chair will submit for a new PAR.

•••• Cont. Revision of C57.12.90-2006 – S. Antosz reported the status of as:

C57.12.90-2010 was published on October 17, 2010; concluding a two (2) year long ballot process. This was a revision of C57.12.90-2006.



Page 2 of 4

Since this Standard is in a 'continuous revision' cycle, the work doesn't end. The Chair already has some completed work for inclusion into the next revision.

There are several WG's and TF's in various subcommittees which are working on changes to this document. Between now and the Spring 2011 meeting, the WG Chair will review these efforts to try to determine the status of their work and when it might make sense to revise the document again. Maybe this can be done quickly in 2 years, but that has not been possible in the past.

Once the anticipated schedule is determined, the WG Chair will submit for a new PAR. This will likely be sometime in 2011.

A quorum was not present, as only 3 of the 8 members were in attendance. Copies of minutes were circulated and reviewed; however, no motion was made to approve.

Steve presented Annex A (informative) to the group for discussion. Due to lack of quorum there was not any action taken. Charles Sweetser agreed to update a table to detail auto-transformers. It was also suggested that this table be moved into the main document to further detail clock notation and Annex A would continue to be informative with the purpose of educating the unfamiliar user of clock notation. Steve and Charles will to have this prepared for the spring meeting with the intent to ballet this standard right after this meeting.

•••• PC57.12.80 – Terminology for P & D Transformers – B. Chiu The document is through REVCOM and in publications hence there was no meeting.

•••• WG on Revision of IEEE C57.152 (old 62) –Jane Verner –This was the 8th meeting for Working Group. A total of 87, with 57 Guests were in attendance, including 30 Members (quorum present) and with 2 requesting membership. It was asked if any patents were related to the work of the group; there were none. The spring 2010 Houston meeting minutes were approved. Committee membership was reviewed with regard to quorum rules.

Draft 4.1 has been issued and posted on the website.

One web meeting was held since the Houston meeting regarding the following:

Section 6.2.6 Insulation Resistance Test which was authored by Ajith Varghese,

The Diagnostic Tests Chart for Commissioning, In-Service and Post Faults

Informative Annex G Dielectric Frequency Response by Poorvi Patel

Section 6.1.2 - Ratio/ Polarity/Phase. A team comprised of John Herron, Jeff Foley, Paul Salvato and Peter Werelius contributed to the section.

The Work Plan spreadsheet has been updated to show progress. All sections have been presented, reviewed and revised except Induced Testing and the Normative References need work. The spreadsheet is color coded to show the clause status. If the Comments column is green, the clause has been reviewed before the group and had another individual review and is ready for publication. If the comments are in yellow, work is in progress. Red indicates more work is required.

John Herron introduced Wolfgang Hauschild as his guest. A tutorial was given on power electronic equipment that can be used in modern electric power systems especially for testing of power transformers. In tests and measurements of transformers with induced voltages (HV withstand tests, PD measurements, no-load and short-circuit loss measurements), static frequency converters can efficiently replace motor-generator sets. Test systems based on static frequency converters generate an AC voltage with continuously adjustable frequency (e.g. 40 to 200 Hz), require minimum test power due to self-compensation in HV withstand and PD testing have no moving parts, and can be transported to the field. They can be completed by capacitor banks for the loss measurements. Dr Hauschild described the design of both, mobile and stationary transformer test systems, as well as the experience with their application. A comparison between motor-generator sets and static frequency converters delivers a clear indication that the future of transformer testing will be dominated by static frequency converters.

Craig Stiegemeier also discussed his experiences with field testing with power electronics test sets in mobile trailers.

Dr. Lemke provided an update to the Partial Discharge Section and references based on the recently approved C57.113 document. Tauhid Ansari agreed to review this document for applicability to Field Testing.

Peter Zhao mentioned that the Bushing Subcommittee had concerns with the bushing power factor recommending 0.5 limit while the Field Test Guide suggests a limit of 1.0 power factor. Further review of this topic will be given.

Oleg Roizman mentioned that the Moisture in Oil needs to be updated to reflect work of this specific Task Force. He and Miak Koch will provide comments and then their proposed changes can be discussed in a web meeting to be held in early December, 2010.

The WG hopes to finish basic comments and final edits by the end of the year with a ballot among the WG early next year.

•••• TASK FORCE on IEEE-IEC CROSS REFERENCE – J. Sim - the following was reported:

A quorum was not present (33 attendees, 4 members, and 29 guests with 0 requesting membership).

The IEEE-IEC Cross reference is planned to be completed in the spring and posted to the website. It will be made available to the IEC, especially TC14, TC36 and a few other committees.

Updates on TF progress to date.

• IEC 60076-1/C57.12.00/C57.12.90 – May need to be updated when FDIS is issued for IEC 60076-1, which has not been circulated to date.

• IEC 60076-2/C57.12.00/C57.12.90 – Hasse Nordman to complete after IEC 60076-2 publication. This has just been circulated as FDIS today.

There was no new business. The complete project list, cross reference list and assignments will be available in the folder for the Task Force on IEEE-IEC Cross.

•••• TASK FORCE on IEEE-IEC Harmonization – Jeewan Puri - The following scope provided to the TF for comments: The TF attendance was 4 members and 12 guests.

The minutes of the last meeting in Houston, TX were approved as submitted.

This Task Force has been formed to develop clear pathways toward developing harmonized standards to meet the needs of the future. The efforts of this task force will be focused on the following:

o Define clearly as to what the harmonization of standards is supposed to accomplish.

o Develop guidelines for harmonizing a standard in part or in its entirety. This will include defining the objectives, deliverables and the proposal process.

o Define a streamlined process for using copyrighted information from IEEE and IEC standards.

o Define procedures for maintaining and updating harmonized standards.

Based on the above, the task force will publish a position paper summarizing the harmonization process, its deliverables and benefits to the industry.

Ms. Jodi Haasz presented a guide that she has proposed for the harmonization of IEEE and IEC circuit breaker standards. This guide defines procedures for writing harmonized standards through the following process:

o Joint standards development for dual logo publications.

o Adopting a standard without modifications for dual logo publication.

o Adopting a standard with modifications.



Page 4 of 4

o This guide has been produced within the bounds of present agreements with IEEE and IEC standards management. It was proposed that this document should be extended to include harmonization procedure for adopting parts of IEC standards and vice versa.

The discussion that followed made the following points:

o The IEC and IEEE document structures are quite different. Therefore the harmonization procedure should enable the writers to adopt any suitable parts of the standards for making them compatible.

o Simple procedures should be developed for the writers to declare their intent to harmonize, its extent and benefits to IEEE and IEC.

o Define a common planning process between IEEE and IEC that should take place before initiating a new standard. This should include identifying the related technical information that exists, its compatibility for harmonization.

o Obtain joint commitment for supporting the harmonization project.

o It was agreed that Ms. Haasz and Paul Jarman will jointly develop this document for discussion in our next meeting.

There was no new business.

5. Old Business

No old business was raised.

6. New Business

No new business was raised.

7. Adjournment

The motion to adjourn by Chair made and hearing no objections; the meeting adjourned around 5:15PM.

Please forward suggestions for nomination for the next (2011) PES WG Recognition Award tomy attention, ASAP, so a nominee can be selected and forwarded to PES.

6.6 Transformers Committee Meritorious Service Awards

http://standards.ieee.org/sa/aw/



In 2008 we initiated a process of additional recognition for Meritorious Service and OutstandingContributions to the Committee. Suggested qualifications have been developed from a review ofsimilar awards presented by other IEEE Technical Committees or Societies. General examplesfor qualification for the awards include the following: To recognize continuing exemplary service in notable technical contributions to multiple

Committee projects/documents over a sustained period of time To recognize an achievement of major value and significance to the Committee. The

achievement can be a specific, concisely characterized accomplishment, as opposed to acollection of different efforts.

As with the IEEE Education Society Meritorious Service Award – “to recognize pioneeringcontributions to the administrative efforts of the Society over a period of years, as evidencedby dedication, effort, and contributions.”

If you have any additional thoughts on qualifications for Meritorious Service Awards, and if youhave potential nominees to suggest, please contact me. Award nominees will be reviewed by theAwards Chair and the SC Officers.

6.7 Member Certificates

We will continue with the process of providing a framed Certificate, certifying Membership inthe Committee, to new Members. The intent is to provide a symbol of recognition ofMembership status, in a format suitable for display. The Certificate will indicate date ofacceptance into the Committee, and will be signed by the Committee Chair. We will also send aframed certificate to everyone who is currently a member of the Transfofmers Committee. It wasoriginally intended to hand these out at the Thursday main committee meeting however in theinterest of time we have decided to mail these directly. You should receive your placque by theend of this year (2011).

This program is one small way of recognizing your support for the Committee. The Certificatesrepresent the appreciation of the Committee, and of your Committee Officers, for your service tothe Committee, to IEEE, and to our Industry. We hope you will display your MembershipCertificate proudly at your place of business, and encourage others to join us in our work.

6.8 Nominations for IEEE, PES, and Technical Council Awards

There are no nominations in these categories at this time. Regarding IEEE Fellow Nominations,we have missed the opportunity for preparation of nominations for the 2011 Class of IEEEFellows. We need to think about nominations for 2012. Borrowing from the IEEE Awards webpages (http://www.ieee.org/web/membership/grade_elevation/grade_elevation.html): “The gradeof Fellow recognizes unusual distinction in the profession and shall be conferred only byinvitation of the Board of Directors upon a person of outstanding and extraordinary qualificationsand experience in IEEE-designated fields, and who has made important individual contributionsto one or more of these fields.” Nominations, including references by at least five present IEEEFellows and optional additional endorsements, must be completed and submitted by March 1 ofeach year for the following year’s Class of Fellows.

9.1.5 Working Group Reports 9.1.5.1 Underground Single Phase Transformers (C57.12.23) – A. Traut, Chairman

The WG did not meet. The document was published in April 2009 and is valid until 12/31/2014. The WG has no new issues to address so it will be inactive until revision or reaffirmation is required.

9.1.5.2 Three-Phase Underground-Type Transformers (C57.12.24) – Giuseppe Termini, Chairman

1. The meeting was called to order by the Chairman at 8:00 a.m. on Monday, October 25, 2010 in the Varley Room of the Hilton Downtown Hotel. Brian Klaponski acted as the recording secretary.

2. The first discussion was about the roster and membership on this WG and a quorum. There was a quorum for this meeting.

3. An agenda was presented and introductions were made. The Chairman asked that any consultant attending who were being paid to attend by representing organizations to identify themselves during the introductions and to identify their affiliation. The meeting was attended by 9 members and 18 guests. One guest requested membership.

4. The Chairman asked if anyone in the Working Group knew or had knowledge of any existing or pending patents that may affect the work on this standard. No one responded as having knowledge about any patents affecting this WG.

5. The Meeting Minutes from the previous meeting in Houston on March 8, 2010 were reviewed and approved with an addendum – in the note on topics, Item 4 should read .” ............ and the possibility of 55º C rise instead of 65º C rise ............”.

6. The Chairman indicated that he had reviewed the comments from the recent ballot and determined that there were no issues to carry forward in our new standard review.

7. Marcel Fortin made a presentation on tank rupture. As a result of the presentation and follow-up discussion, it was agreed to request the Underground SC to support an “arc fault test” Task Force that will perhaps be initiated by the Distribution Transformer SC.

8. In preparation for a new PAR a motion was made to leave the Title as is without including vault types as part of this standard. The motion was voted on and approved. The Working Group members were asked to review the Scope and Purpose and this will be discussed at our next meeting.

9. The meeting was adjourned at 9:15 am with the next meeting set for San Diego in April 2011.

9.1.5.3 Liquid Filled Secondary Network Transformers (C57.12.40) – Brian Klaponski, Chairman

1. The WG met on Monday, October 25, 2010 at 09:30 am with 12 members and 11 guests. One guest requested member status.

2. The chairman reviewed the patent legal issue and asked whether there were any patents or patents pending that would affect the WG or standard. None were identified. However, John Crouse of GE will check if there is a patent or pending patent on tank rupture and will update the WG at the next meeting.

3. The minutes of the March 8, 2010 meeting in Houston, TX were reviewed and approved. Carl Niemann made a motion to approve the Meeting Minutes and Steve Schroeder seconded the motion.

4. The meeting consisted of the review of the comments incorporated in Draft 9 of the standard dated October 15, 2010. Draft 9 now incorporated changes agreed upon at our Houston meeting plus some suggestions in regards to the flex connectors that had been submitted by email by John Rossetti a WG member.

A. There was an extensive discussion on the third paragraph. of Section 3.1. A vote was taken to remove the words:” ……..and without exceeding a 110ºC hotspot temperature” from the last sentence of the third paragraph of Section 3.1. This change was voted on and approved.

B. The remaining of the meeting focused on the rest of the changes in the Draft. A suggestion was made to include a picture of a typical “split block” in the standard. The Chairman will take a picture of a typical split block and circulate it to the WG prior to incorporating it into the standard.

5. The Chairman will make the above changes and then start the ballot procedure. It is important to publish a new document because this spec has not seen a major revision in over 10 years.

6. The meeting was adjourned at 10:50 am with the next meeting set for San Diego, CA in April 2011.

7. Post meeting note - the ballot pool has been started.

9.1.5.4 Secondary Network Protectors (C57.12.44) – Bill Wimmer, Chairman 1. The meeting was called to order and a review was made of the members present. A

quorum of the members was not present. Introductions were made of all members and guests present.

2. A call was made of the attendees to disclose any patents that may have an impact on the activities of this working group. No patents were brought forward.

3. Old Business - Revisions to Document:

A. Section 6.2.1.3b: “The network relays(s) shall be tested at 1500 V at 60Hz for 1 min.” Is this left over from the electromechanical days? (Mark Faulkner). Consensus was made to leave statement in place but add “ electromechanical relays only”.

B. Section 5.2.3.3: “At the end of the test, the network protector shall be capable of meeting its interruption rating and capable of carrying rated continuous current without exceeding the temperature rise limit.” Does this require a second heat run test? (Mark Faulkner) Consensus was made to revise the statement to as follows:

“At the end of the test, the network protector shall be capable of meeting its interruption rating and capable of carry rated continuous current without exceeding the temperature rise limit based on the micro-ohm change and the original heat run test.”

4. New Business None

9.1.5.5 Ventilated Dry-Type Network Transformers (C57.12.57)

1. The WG was not scheduled to meet.

9.1.6 Old Business Paten Issue from 3/10/2010 - “We need to understand if there are issues that will affect the availability of products that are parts of our specs. We need transparency to ensure proper decision making. Should not there be full disclosure (of patents).” There continues to be zero disclosure of FR3 patents at the meetings. Identify and submit a Letter Of Assurance request on a patent issue. Making a statement of essentiality Suggestion – deal this at the sign-up level so that the disclosure of any patents is dealt with prior to coming to the meeting – present system is simply wasted meeting time

9.1.7 New Business 1. Brian Klaponski: Typically one goes through the administrative process once every 5+

years, so on your own it can take several days to get through. When you can sit down with Matt Ceglia it takes 5 minutes to go through. Matt should be at every meeting to provide the valuable and needed assistance – IEEE is presently allowing Matt to attend just every other meeting. Changing headings etc. from the template at the start of the project to the current year is another example of wasted administrative time. NOTES – previous versions allowed notes below the paragraph to which they applied, which is user friendly. The current standard is to put the notes at the bottom of the page, which is not user friendly and will result in many not noticing them at all. A. Suggestion: Create an executive whose job is to improve the process. B. Brain has volunteered to run a lean process review of the system

2. Giuseppe Termini: 123 Sign Up System does not allow you send a PDF file greater than 1 Mb. Do not think it is a good idea to post the working document on the Transformer Com page as it should not be available to all. Brian – send three items out to the group, Comes back as too big but no limit shown. Tried 12 times to send out draft. Suggetion – fix the system so that larger files can be emailed to the WG members.

9.1.8 Future Meetings

9.3.4 Working Group (WG) and Task Force (TF) Reports

9.3.4.1 WG - Revision of C57.19.00 - Keith Ellis, Chair

REAFFIRMATION REPORT:

All ballot comments and negative ballot issues have been addressed with no objections fromthe voters.

During this process it was found that a number of paragraph numbers were not provided in thefinal published version of the documents. The missing numbers make it confusing when oneclause refers to another specific clause in the document.

IEEE is looking into how this happened and will likely publish ERRATA with the missingparagraph numbers re-inserted.

IEEE has not gotten back to me since our discussions last fall.

2

The reaffirmation process was extended for one year to resolve this issue.

9.3.4.2 TF - Revision of C57.19.100 – Tommy Spitzer, Chair

The working group met on Tuesday October 26, 2010 at 11:00 am with 12 members and 23guests present. This did not constitute a quorum.

There were no patent disclosures.

Chair informed the group that the deadline for completing the revision was missed, and a PARextension has been applied which will move the completion date to Oct. 17, 2011. The revisionis complete with the exception of restoring Figure 3. Michael Williams volunteered to restorethis figure. Peter Zhao suggested that since IEEE had been questioned about different powerfactor values being acceptable in different standards that additional wording be added toeliminate this confusion. After restoration of figure 3 and the explanation added, Draft 5 will beposted on the website for review by the working group. When all comments have beenresolved I will present it to IEEE for balloting.

The meeting adjourned at 12:15

IEC/IEEE JMT5 Dual Logo Standard IEC/IEEE 65700-19-03Report of Meeting Toronto, Canada

The third meeting of the Joint Maintenance Team was held on Thursday, October 28th

2010from 13.00 to 16.00. A total of nine persons attended including eight IEEE members and threeIEC members (two being common to both groups). The meeting was chaired by joint convenorsLes Reckseidler (IEEE) and John Graham (IEC).

Minutes of the Houston meeting document 36A(JMT5_Graham)04 were approved.

There were no patent issues raised.

The agenda document 36A(JMT5_Graham)08 was approved.

Following the Houston meeting the results of comments discussed have been circulated anddiscussed further by email resolved comments were included in a fourth draft (IEC/IEEE 65700-19-03 Draft 4) which was circulated to members together with a revised compilation ofcomments in July 2010. These documents were reviewed at the meeting.

The main technical comments were discussed in detail and many issues resolved.Clause 4.5 – Definition of voltage U1 for creepage distance calculation.It was agreed that the voltage should take consideration of both DC and AC components ofvoltage. The use of either peak or rms voltage AC voltage was discussed. It was agreed thatrms phase to ground voltage was more appropriate. This will be included in the next draft.

Clause 8.4.1 Emission TestThe application of a DC voltage for the emission test was discussed and decided not to beappropriate technically. It was agreed that an AC voltage equal to 1.1 x Up / √2 should be applied in a test method following IEC60137 2008. Up as defined in clause 4.1.2 will be added tothe list of variables in clause 6.3.

Clause 8.5.2 Temperature rise testDraft 4 give one method for the determination of the equivalent test current. An alternativemethod was presented by Mr Testin as 36A(JMT5-Cardano)09v2. It was agreed that the basisfor this method should be included in the document as an alternative method of calculation asan appendix. Mr Testin agreed to prepare the wording for the next draft.

Clause 9.2.1 Dry lightning impulseThe need to apply SIL as a routine test where the value exceeded 83% of the BIL wasdiscussed again. Contributors have stressed the importance of both wave shapes underdifferent conditions. It was agreed to alter the sequence of the wording to give more priority toSIL while maintaining the option for both or BIL alone where agreed.

Clause 9.5.1 Polarity reversalIt was agreed to include the same rules for sample testing of bushing rated below 150kV ratingas given in clause 9.4.1.

Clause 8.2.1 Lightning impulse (Type test)It was agreed that chopped waves with a peak voltage level of 121% of the full wave valueshould be applied following IEC60137 2008.

Clause 3.15 OilIt was agreed that the definition should include other oil types as already included inIEC60137 2008.

References: All references are to be checked for the next draft for applicability and validity.

There was no other old or new business.

9.3.4.5 IEC Bushing Standards Activity - John Graham of Trench Ltd., UK

IEC BUSHINGS STANDARDISATIONThe IEC bushing committee SC36A has not met since the IEC General Session in Sao Paulo,Brazil during the week of November 17

th2008. The next meeting is planned for October 2011 in

Melbourne, Australia.

IEC60137 “Insulated Bushings for Alternating Voltages above 1000V”

Edition 6 was published in July 2008, the maintenance date for IEC60137 is set at 2011.During future revision the working group should address inconsistencies in the test method fortemperature rise of external connections – this inconsistency also exists in IEEE C57.19.00.

mailto:[email protected]

5

It is expected that at the Melbourne meeting a new work item proposal will be raised to set up anew maintenance team to review the document.

IEC62199 “Bushings for DC Application”

SC36A MT5 is working with The IEEE Bushing subcommittee with a joint working group toproduce a dual logo document.Two meetings have been held, in Lombard (Fall 2009) and Houston (Spring 2010). Work hasproceeded by email to avoid a meeting in Europe. A fourth draft has been circulated andcomments received. The next meeting will be held on Thursday Oct 28

thin Toronto.

It is hoped to proceed to a Committee Draft for Voting with the main items to resolve;- Creepage distance calculation – specification of the appropriate voltage.- Emission test

9.3.5.1 Busing Service Conditions - Devki Sharma and Tommy Spitzer

The question was raised by Devki and Tommy regarding the coordination between the bushingstandard C57.19.00-2004 and the application guide C57.19.100-1995.

Standard C57.19.00 Clause 4.1 includes usual service conditions as follows:- Ambient air temperature not to exceed 40 deg C and average over 24 hours not to exceed

30 deg C.- Temperature of transformer insulating oil in which the inboard end of the bushing is

immersed not to exceed 95 deg C average over 24 hours.- The external terminal and bus connections not to exceed 30 deg K rise over ambient.

Application Guide C57.19.100 clause 4.1.1.1 contains advice stating that rated temperatures inthe bushing may be exceeded during some high temperature loading conditions resulting inreduced bushing life expectancy. Clause 5.2 gives advice for derating of bushings under thishigh temperature condition.

The concerns expressed during the discussion are that these two items are confusing and mayeven appear to be in conflict with each other. The wording and advice may need to be bettercoordinated in future revisions of the documents. This item will be carried forward to the nextmeeting for further discussions.

Loren Wagenaar has provided his comments on the subject in writing, which will be discussedduring the 2011 Spring Mtg.

9.3.6.2 Breaker Bushings – Activity in Breaker Committee

It was reported that Switchgear Committee will ballot a Standard for Circuit Breaker Bushings(PC37.017, Standard for Bushings for High Voltage (over 1000 Volts ac) Circuit Breakers andGas Insulated Switchgear). Interested individuals should join the balloting group.

Survey of Bushing SubcommitteeC57.19.01 Action Needed to Extend Validity of Standard

Survey ContentChair sent out a Bushing Subcommittee Survey on May 13, 2010 to the 36 members of theBushing Subcommittee using the AM system.. The text of the survey was:

IEEE Bushing Subcommittee Survey 0513-1 - Action Required for C57.19.01 -Responses Due by May 28, 2010

As discussed in the Subcommittee Meeting in Houston, Standard C57.19.01-2000,"IEEE Standard Performance Characteristics and Dimensions for Outdoor ApparatusBushings" is scheduled for administrative withdrawal at the end of 2010 unless action istaken to extend it's life. The possible life extension actions are reaffirmation or revision.This standard was reaffirmed once in 2005.

A. Should we apply for a second reaffirmation or apply to start a revision?

B. If we start a revision effort, please list any sections or topics that you believe shouldbe changed, added or deleted.

C. If we start a revision effort, do you have suggestions for a Working Group Chair?

I suggest a revision is in order to address issues for the modulus of elasticity on 200 & 600Abushings used in equipment defined by C57.12.90-2006. The in-service failures of thesebushings needs to be addressed.

The revision should at least include:

1) Add back the voltage classes of 25 kV (150 kV BIL) and 115 kV (550 kV BIL).These two voltage classes are still among the most common bushings ordered by bothOEM and utilities.

2) The TBI cantilever requirements should be put back because the bushingmanufactures did not change the designs to reduce the bushing mechanical strength inorder to “meet” the lowered requirement specified in the 2000 version; instead, majorbushing manufactures still stick to the 1991 version for the cantilever test. For the users,the high cantilever strength means the bushing could tolerate high pulling force in thefield and may have a better chance of surviving after mechanical shock such as seismicevents.

3) The referred standards should be updated to the most up-to-date versions. Forexample, the transformer standard should be C57.12.00-2006 rather than C57.12.00-1993.

We should take all listed styles though 230 kV to 5,000 amps as we are seeing larger andlarger power transformers being purchased. Also, I have seen 230 kV 4000 and 5000 ampbushings with odd "L" dimensions. When I asked the manufacturer why they designed thebushing with the odd "L", their response was; "that rating is not covered by the standards".

So today there are 230 kV design out in the field with 54" "L" dimensions, making obtainingreplacements a long lead-time issue.

Also, it is time to dump the breaker plates on HV bushings. By replacing the breaker platewith a smaller connection plate with a integral 2-hole or 4-hole spade. Attached aredrawings of our design at 115 kV, fixed conductor and a 500 kV high current draw leadbushing with the 2-holes spades delivered to Brazil. The Transformer OEM confirmed thatthese designs lower the cost of their transformer. And we know it lowers the cost of thebushing.

My opinion is that since the industry has not abandoned the 15 kV and the 25 kV ratings,they should be added back into the document.

Action TakenA PAR request for revision has been submitted for the December Standards Board meeting.Arturo del Rio will chair the new working group. The first meeting of the Working Group isplanned for the Spring 2011 meeting in San Diego.

Dry Type Transformers Subcommittee – Unapproved Meeting MinutesOctober 27, 2010 – Toronto, Ontario Canada

2010 Toronto Dry Type SC Minutes - Final.doc Page 1 of 6

9.4 Dry Type Transformers SC Chair Charles JohnsonSecretary Lewis Powell

9.4.1 Introductions and Approval of Minutes

The Dry Type Transformer Committee meeting began at 1:34pm Wednesday, October 27 in the TomThomson room C of the Hilton Downtown Toronto Hotel with introductions of members and guests.There were 13 members and 8 guests present. As 18 members were required for a quorum, theHouston Texas meetings were not approved. The Chair then asked if anyone knew of any patentrelated issues; none were identified.

9.4.2 Working Group/Task Force Reports

The next order of business was the presentation of the reports of the various working groups and taskforces. See the following sections for the individual reports:

9.4.2.1 IEEE PC57.12.01 - Dry Type General Requirements Chair Tim Holdway

1. The working group met in the Johnston Room of the Hilton Toronto Hotel

2. The meeting was called to order at 11:03 AM by Chairman Tim Holdway

3. The meeting was convened with eleven (11) members (out of 21 – therefore a quorum wasreached with 52% attending) and 10 guests present.

4. The minutes of the Houston March 8, 2010 meeting were approved.Motion: Mark GromlovitsSecond: Sheldon Kennedy

5. Attendees were asked if they knew of any patents that may be related to the work of this workinggroup. No patents or patent claims pertinent to C57.12.01 were identified by working groupmembers.

6. Old business

NameplateAfter the Houston meeting Aleksandr Levin provided Tim Holdway with the draftC57.12.00 Section 5.12.2 part 13 for distribution to the WG. The proposal includedadding the words ‘DOE Compliant’ to the nameplates. An informal polling of themanufacturers present showed that the addition of text on the nameplates wasinconsistent in the industry - some did, some didn’t, and each that did had their ownversion. A comment was made by Dhiru Patel that the DOE was considering amandatory marking or text on all nameplates and the decision was made to table thisdiscussion until after the DOE had made its ruling in the spring of 2011.

Altitude CorrectionIn Houston, Rick Marek stated that Section 4.2.5 is vague on what dielectric tests areaffected for altitudes above 3300ft (1000m). Three written suggestions were distributedto the WG and the discussion revolved around the one submitted by Tim Holdway.Mark Gromlovits suggested a modification to the text proposed by Tim, but this nevermade it to the motion phase.

The discussion moved to the technical aspects of dry type transformers that make altitudecorrection difficult since they use a complex combination of solids and air for dielectrics.



The values currently in Table 1 are for a complex insulation system as they do not matchthe properties of air above 1000m per IEEE STD 4. The concern centered on the higherstresses placed on the solid inter-winding insulation resulting from the dielectric testvalue correction factors for the thinner air at higher (>1000m) altitudes, particularly forcast technology.

Art Molden pointed out that IEEE STD 4 – 1995 Section 16.4 addressed this issue andgave guidance on how the manufacturers could address higher inter-winding stresses onsolid insulations. One option was to design for higher inter-winding stresses and theother was to prove the terminals (in open air) were suitably spaced through a fixture orcoil simulation that would be dielectrically tested. A suggestion was made to add IEEESTD 4 as a reference in section 4.2.5, but this was not made a motion.

The meeting moved on to other topics with no open motions and no votes taken on thisissue.

Partial DischargeAs an action item from Houston, Mark Gromlovits suggested that 20pC be used for allopen ventilated (open wound non cast) transformers. Dhiru Patel suggested that thisvalue was too low and the values be left ‘as-is’ for non cast dry type. Other suggestionsincluded adding text explaining surface discharge in open ventilated or having no valuesfor open ventilated at all. The group decided to continue the discussion after eachmember could do more research.

A motion by Rick Marek to use the test method and 10pC level for cast windings wasseconded by Chuck Johnson and was passed by a vote of 6 for, 4 against, and 1 abstain.

The test method for open ventilated was not decided and Mark Gromlovits will provide asuggestion to the WG chair before the next meeting in San Diego.

7. New businessNo new business was raised due to time constraints

8. Next meeting: Spring 11: April 10-14, San Diego, California

9. With no further business, the meeting was adjourned at 12:18 PM.Motion: Rick MarekSecond: Sheldon Kennedy

9.4.2.2 IEEE PC57.12.91 - Dry Type Test Code Chair Derek Foster

1. The working group met in Johnston Meeting Room of the Hilton Downtown Toronto. Themeeting was called to order at 3:15 PM on Monday October 25, 2010. The working group metwith 5 members and 9 guests present.

2. There were no patent issues regarding this standard.

3. The minutes of the last meeting, held in Houston, could not be approved, since not enoughworking group members were present for a quorum.

4. Old Business

This standard is now open for ballot until November 21, 2010.

The ballot pool has 101 members.



The PAR for revision of the standard expires at the end of December, so a one year extension hasbeen applied for.

Since there were not enough members at the meeting for a quorum, this was an informationalmeeting, and some of the topics proposed for consideration in the next revision were brieflydiscussed.

Marcel Fortin agreed to provide input for the next revision, regarding section 12 of the standardon short-circuit tests and also on section 10 on partial discharge tests.

A task force will be established within the working group for the next revision, to review theproposed revisions to temperature rise test procedures in section 11 of C57.12.90, to see how thismay be used in the dry-type transformer test code.

Marcel Fortin gave a presentation to the working group on the loading back method oftemperature rise testing. A copy of the presentation will be sent to all members of the workinggroup.

5. The meeting ended at 4:00 pm.

9.4.2.3 IEEE PC57.12.52 - Sealed Dry Type Power Transformers Chair Sheldon Kennedy

1. The Working Group met on Monday, October 25, 2010 at 9:30 AM with 11 members and 5guests present. Sheldon Kennedy chaired the meeting. There were two new members addedduring this Working Group meeting bringing the total WG membership to 14. We had a quorumfor the meeting.

2. The IEEE disclosure statement was read. There were no patents pertaining to this standards workfor which any members had awareness.

3. Minutes of the March 8, 2010 meeting in Houston, Texas were reviewed and approved.

4. Draft 3 of the document was placed on the IEEE Transformers Committee website. A survey wascirculated to the Dry Type Subcommittee Draft 3 before the meeting. There were no realnegative comments received, but there were some editorial comments and approved withcomments returns.

5. The Working Group reviewed the changes made in Draft 3.

6. Casey Ballard commented that the document layout should be changed so that Table 5 fit intoClause 6.2 better instead of being on the next page, as it was due to the size allowing it to fitbetter there. Casey also volunteered to update some of the older hand drawn figures importedinto the standard and make them electronic figures. Casey will try to get these back by the end ofNovember for inclusion in the document.

7. Rick Marek commented that clause 5.5.2 should be C57.12.70, not C56.12.70. He alsocommented that clause 6.1.2 has a typo and should be “heat” transfer, not “het” transfer. Rickalso commented that the reference in Clause 9.1 to C57.96, the dry type loading guide should notbe mandatory as it relates to ambient temperatures. The Working Group decided to say that thewording should be changed to “refer to IEEE C57.96 for guidance.”

8. Gene Blackburn commented that Clause 9.3 should be Clause 9.5 in line 24 on page 11. He alsonoted that on page 17, line 19 the reference has a type and should be changed from “UEEE” to“IEEE”.

9. The above changes will be incorporated and the revised draft will be circulated among theWorking Group members as a 30 day survey. If this is successful, and there are no other



comments, the chair will try to get the document to an official ballot, hopefully by the end of theyear.

10. There were no other comments.

11. There was no other old business or new business.

12. The meeting was adjourned at 10:30 AM.

9.4.2.4 WG for Revision of IEEE C57.16: Dry Type Reactors Chair Richard Dudley

The W.G. for the Revision of IEEE C57.16 (Dry Type Reactor T.F.) met on October 25, 2010, at8:00 a.m. in the Johnston Meeting Room of the Hilton Downtown Toronto Hotel in Toronto, Ontario.There were 12 members and 6 guests present. There are 24 members in the WG, including 5corresponding members; therefore, there was a quorum. The following are the highlights of themeeting:

1. Introductions were made and the attendance list circulated.

2. IEEE patent policy was reviewed and no issues were raised.

3. The minutes of the W.G. meeting in Houston, Texas were approved.

Note: The minutes of the WG meeting in Toronto, Ontario will not be approved until the WGmeeting in San Diego.

4. The results of the ballot of Draft #8 were reviewed: 90% response, 87% approved, 10 negativeballots. Seven of the negative ballots included arguments that were largely editorial and caneasily be dealt with outside the WG meeting. Three negative ballots raised jurisdictional scopeissues with Annex F. Is some material in Annex F dealing with CB TRV issues related to theapplication of reactors outside the scope of the IEEE Transformer Committee and more withinthe jurisdiction of the IEEE Switchgear Committee? Focus of the rest of the meeting was onresolving this basic issue. Highlights of the discussions are as follows:

(i) Annex F will be somewhat simplified; eliminate details relating to switchgear and TRVimpact. Appropriate switchgear standards will be referenced, especially PC 37.011,which is in draft stage.

(ii) Pierre Riffon’s draft, that he produced based on the ballot comments, seemed to meet theabove criteria and was discussed in detail. Modifications were made to make the focus“the reactor” and “capacitance mitigation”. It was agreed to put material related to reactorusage rationale at the beginning of the annex as it would also refocus the annex on “thereactor” and “application”; including the possible impact of the TRV seen by the CB.Capacitor application guidelines and possibly type test implications will be included;basically temperature rise test and short circuit test.

(iii) Pierre Riffon will revise his draft for Annex F based on the discussion. It will becirculated to WG members for comment. A further draft will be produced and theChairman will send it to Ken Edwards of the IEEE Switchgear Committee for approval.WG members are asked to look at the reactor TRV CB issues from both sides and focuson “the reactor” and “capacitance mitigation” vs the “CB” and “impact of TRV on theCB”.

(iv) Other comments from the ballot will be reviewed by the Chairman. Changes will be madeby the Chairman or the Chairman will ask for help from the WG. It is hoped that a newdraft of PC 57.16 can be ready, and even balloted, well before the San Diego WGmeeting.

The WG meeting adjourned at 9:15 a.m.



9.4.2.5 WG Dry Type Loading Guide C57.96 Chair Rick Marek

1. The second meeting of the working group was held in the Varley Room of the Hilton DowntownToronto Hotel at 1:45 PM with 12 members and 6 guests in attendance. Introductions weremade, and the attendance sheet was passed around. There were no patent issues. As there was aquorum, minutes of the last meeting were approved as submitted.

2. The Title, Scope and Purpose were reviewed by the Chair. He then reported the results of thesurvey concerning the IEC and IEEE loading guides, which were circulated to the members. Thefollowing questions were asked:

IEC document should be used as it is with no changes 0 IEC document should be used with small changes 2 Revision should be a blend of the IEC and IEEE documents 8 IEEE document should be revised 2

3. The Chair asked for comments on the two circulated documents. Since there were none, hedescribed the differences in the two documents. The IEC document arbitrarily defines the life ofa transformer at 20 years, or 180,000 hours, and is not based on any specific test data. The IEEEdocument isn’t tied to a specific life time, but is based on actual tested insulation systems foropen wound units. The IEEE guide then addresses cast transformers in a second completedocument within an annex, similar to the IEC, since there are no published cast insulationsystems. However, no specific life time is mentioned. This prompted a large discussion aboutinsulation systems, material testing, differences between IEC and IEEE procedures and thedifferences in technologies.

4. The Chair then noted that this standard is really a guide for the user and asked who in the groupactually uses the guide. Three of the four users in the group each related experiences, althoughnone actually used the document. It was noted that while the document is not generally used bythe manufacturer, it does document dry-type product capability and is a communication tool forthe customer. In many cases the user is more familiar with liquid-filled units and needs tutorialinformation concerning dry-type transformers. It was also clarified that the document scope doesnot include 600 volt class units.

5. Mark Gromlovits suggested that the IEC and IEEE standards be compared side by side. TheChair asked for volunteers to compare the two documents and to select the portions that shouldbe used in the revised guide. He will assign the sections. Six members volunteered: JimAntweiler, Derek Foster, Mark Gromlovits, Tim Holdway, Rogelio Martinez and Dhiru Patel.

6. The Chair suggested an approach similar to the IEC standard with one standard for dry-type,which includes both open wound and cast in a single document. The IEC defines the slope byselecting the “halving constant” and then arbitrarily assigns the hottest spot temperature to a lifeof 180, 000 hours, where the hottest spot temperature is 10 degrees less than the insulationthermal class. This is the same hottest spot temperature used by IEEE and is independent of thedifferent ambient temperatures used by the two standards bodies. However, he suggested onedifference in that cast should be assigned a 6 degree “halving constant” as in the IEC guide butopen wound should be assigned 8 or 10, which is more correct for that technology. Themanufacturer would also have the option of using a tested number if available, as noted in theIEC document.

7. Dhiru Patel agreed to review the computer program in the IEEE standard, and possibly convert itto a spreadsheet that could be a very useful tool appended to the published document. The Chairrecommended the removal of the loading tables and curves in favor of equations, which is similarto the IEC standard. However, some objected to the loss of the historical curves, which must be



revised since they are actually incorrectly drawn in the current IEEE document. Phil Hopkinsonand Manguesh Rajadhyaksha volunteered to research the standard and recommend the historicalportions that should be moved to an informative annex.

8. The meeting adjourned at 2:55 PM.

C57.12.28, 29, 30 & 31 – Enclosure Integrity – Bob Olen reported.

There was an introduction of members and guests. The IEEE Patent Policy was presented to thegroup by Bob Olen. The group was asked if there were any patents that needed to be disclosed. Nonewere announced to the group. There were no Consultants present which were sponsored by asecondary source. A quorum of the Working Group's membership was NOT present. The lackof a quorum was caused by the scheduling conflict with the Wind Power Transformer TaskForce meeting.

The minutes of the March 9, 2010 working group meeting were presented. However, theminutes could not be approved due to the lack of a quorum.

C57.12.30 Pole Mounted standard for Coastal Environments and C57.12.31Pole Mounted standard

RevCom approval for both standards was granted on June 17, 2010. IEEE publication of bothstandards was completed on October 7, 2010. Copies of the standards will be provided to themembers of the Working Group in the very near future by IEEE.

C57.12.28 Standard for Pad Mounted Equipment - Enclosure Integrity

PAR approval was received on September 30, 2010 and a line item review of the standard wasthen started. The definition of the padlock device was discussed. The mounting of padmounted equipment to the concrete pad was reviewed. The working group was asked toconsider installation options to obtain security around the base of the cabinet. The waterresistance requirement of the cabinet was also discussed. Two members of the Working Groupvolunteered to review the Enclosure Integrity Test Method to determine if any updates areneeded to the tooling specified in the standard. A problem has been identified with theMunsell color designation included in the standard. Members of the Working Group wereasked to bring a 3" x 6" test panel painted with their current pad mount green coating system tothe next meeting. A color comparison will be conducted at the next meeting. A very briefreview of the coating tests was conducted. Several of the tests will require some slightmodifications.

C57.12.29 Standard for Pad Mounted Equipment - Enclosure Integrity forCoastal Environments

PAR approval was obtained on September 30, 2010. A request was made for the WorkingGroup to review the outdoor corrosion test method and to identify alternative outdoor test sitesor a test method that would yield results in a shorter time period.

The meeting was adjourned at 9:20 AM

C57.12.34 – Three-Phase Pad-Mounted Transformers – Ron Stahara reported.

Ron Stahara called the meeting to order. To establish a quorum, a role call of the members wasmade. From this a quorum was declared. Ron asked that everyone introduce themselves bygiving their name, company and location. Also, an attendance roster was circulated. The IEEEPatent Policy was presented to the group by Ron Stahara. The group was asked if there wereany patents that needed to be disclosed. None were announced to the group. A motion was



made by Jerry Murphy and seconded by Gael Kennedy to accept the minutes of the Lombardmeeting. It was approved by acclamation with no corrections.

Ron asked if the previous working group that had prepared the 2009 version of this standard hadreceived their complimentary copy of this standard. It was found that only Steve had received thecopy. Steve stated he would get with Matt Ceglia and obtain a copy to each individual. AliGhafourian had purchased the standard since he didn’t receive one. e asked if he could get hismoney back. Steve said he would make this request of Matt.

The working group reviewed the topic of extending the range of the standard to 10 MVA in thenew PAR. The concern was the move from Category II to Category III for the 7.5 and 10 MVAsizes as related to Table 2 which lists the nominal impedance levels for the Transformers underthis standard since the Category III transformer includes the system impedance with thetransformer impedance in through fault calculations. After some discussion it was decided that atthese voltage levels and system configurations, it would not be necessary to consider this as anissue and we would just extend the table impedance specification.

Steve stated that based on the information that was shared today, he would produce a Title,Scope and Purpose and he would submit a PAR to NESCOM. The goal would be to acquire aPAR by the next meeting.

The meeting adjourned at 2:40 PM

C57.12.35 – Distribution Transformer Bar Coding – Lee Matthews reported.

The WG met on Tuesday, October 26, 2010 at 1:45 pm in the Tom Thomson Room of the HiltonDowntown Toronto Hotel in Toronto, Canada. A quorum was present for the meeting.

The chairman reviewed the patent legal issue and asked whether there were any patents orpatents pending that would affect the WG or standard. None were identified.

The minutes of the March 8, 2010 meeting in Houston, TX were reviewed and approved.

The chairman discussed the current status of the PAR. The PAR was approved June 17, 2010and will expire December 31, 2014. Draft 1 (D1) of the standard was reviewed. Bob Olen agreedto review ASTM G154 requirements and different types of bar code readers and will advise theWG group at the next meeting.

There was a discussion on different identification technologies besides bar coding. It was agreedto maintain the current Title, Scope and Purpose until more information is gathered on otheridentification technologies. A survey among end users was suggested to determine types ofidentification used.

The Chairman requested the WG to review Draft 1 of the document and forward comments backto him by the end of January 2011.

The meeting was adjourned at 2:35 pm.

C57.12.36 – Distribution Substation Transformers – Jerry Murphy reported.

Jerry opened the meeting at 8:00 AM on Monday October 25, 2010, in the Tom Thomson Room ofthe Toronto Hilton; introductions were made, and the attendance rosters were circulated. No newpatents were disclosed. Since this Working Group was being reactivated after publication of thecurrent standard document in 2007, no roll call of members was necessary to verify quorum sincethis was the first meeting.

A request was made by one person in attendance to have the latest draft of the documentavailable for review on the Distribution Transformer Subcommittee webpage.

Jerry asked the people in attendance if there were any specific comments for discussion. Hementioned the options that the working group had for the next steps in the working groupactivities. One option was to go for reaffirmation. Gary Hoffman said that if the document went forreaffirmation, he would vote negative. Gary mentioned that there were several accessories thatmay have to be considered to be added to the standard. He said that the draft document ofC57.12.10 was practically completed and ready for balloting. In his opinion, it was necessary to



compare the requirements of both C57.12.10 and C57.12.36, to ensure that the differencesbetween Distribution and Power Transformers were clarified, and to identify opportunities forimprovements and changes to C57.12.36. There were other comments that supported thisopinion.

Steve Shull made a motion that Gary Hoffman and Jerry Murphy get together to review the currentversion of C57.12.36, and compare it with the latest document of C57.12.10 that was currentlysubmitted to REVCOM. Ron Stahara seconded the motion and it passed unanimously. After thismeeting between Jerry and Gary is held, a survey within the working group may be required to getfurther comments about the differences between the two standards, which will define the course ofaction. This could range from withdrawing the standard to specific improvements that should bemade to it.

The meeting was adjourned at 8:40 AM.

C57.12.37 – Electronic Test Data Reporting – Did not meet.

C57.12.38 – Single-Phase Pad-Mounted Transformers – Michael Falkenberry reported.

The meeting was called to order by Ali Ghafourian.

A roll call was conducted to determine if a quorum was present. Twenty (20) of the thirty-three(33) working group members were present with one additional member arriving later. Therefore, aquorum was present.

The members were asked if there were any patent issues that needed to be identified associatedwith the work on this standard and none were identified.

The minutes from the March, 2010, meeting in Houston were presented for review and wereapproved.

Marcel Fortin stated that for distribution transformers, a test was needed to ensure fast dynamicpressure withstand of the tank due to arcing faults. He suggested that the working grouprecommend to the Distribution Transformer Subcommittee that a Task Force be established tostudy and determine the appropriate arc fault test for all tank shapes. It was determined throughfurther discussion that a new task force was not needed as Carlos Gaytan's Tank PressureCoordination Task Force is first going to address static pressure but will then procede to addressdynamic pressure.

Tom Holifield provided a draft drawing of low voltage bushing configurations for all voltages thatfall under the new document scope for "480/240 volts and below." The drawing included lowvoltage ratings of 120/240 and 240/480 volts that we had discussed not including in the standardat the Houston meeting. After further discussion, a motion was made and seconded that 120/240and 240/480 volt bushing arrangements be included in the standard. The motion was voted onand of the 20 members present at that time, less the chair (leaving 19 voting members), nine (9)were in favor of including these voltage ratings, five (5) were opposed, and five (5) abstained. Themotion was, therefore, neither passed nor defeated, and it was tabled for further discussion at theSan Diego meeting.

Figure 1A shows the dimension from the outside edge of the X1 spade to the cabinet wall as aminimum of 3 inches for a Type 1 design. A suggestion was made in the Houston meeting toconsider changing this minimum dimension from 3 inches to 3.5 inches, similar to the dimensionfor the Type 2 design in Figure 2B. A survey was sent out to sixty-two (62) working groupmembers and guests to see how this dimension is being specified. Only thirteen (13) responseswere received, not enough from which to make any conclusions. The issue is with the typeconnector being used. It was suggested that the dimension be left as is and allow the user tospecify any exception to that dimension in their specifications. It was also mentioned that if theuser changes this dimension, it could affect other dimensions. All present were asked to returnthe survey and this would be discussed further at the San Diego meeting.

A request was made at the last meeting for a review of Dimension A in Figure 1A to possiblyincrease that minimum dimensional requirement, and similarly in Figures 1B, 2A, and 2B. Afterdiscussion, it was decided that this dimension will remain as currently in the standard.



In the table of dimensions on Figure 1C, the last line of the table has "(when specified, see Note7)" which refers to large interface separable connectors. It was requested that "when specified"be removed. After a discussion of the large versus small interface connectors for 35kVapplications, a motion was made and seconded that the next-to-last line of the table, which is forsmall interface connectors, and the last line of the table, which is for large interface connectors,both be revised to reference the appropriate section from IEEE Standard 386 and to delete thecurrent text in parenthesis for the last line. The motion passed unopposed.

The meeting was adjourned at 12:00 p.m.

C57.15 – Step-Voltage Regulators – Craig Colopy reported.

Membership roster shows 23 members total - Need 12 for Quorum - 15 showed up. .

Lombard unapproved Minutes were published one year ago and were approved at this meeting.Motion: by Dan Sauer and second by Ron Stahara. This motion was unanimous approved.

Motion for approval of the Porto Portugal unapproved minutes was made by Lee Matthews andseconded by Ron Stahara. This motion was unanimous approved.

Announcement for notification of the Patent issues and associated conflicts was made with noresponse.

IEC TC 14 Dual Logo Comments - Paul Jarman, chairman of the IEC Technical Committee 14Power Transformers who does the coordinating of the technical groups had discussions on thepossibility of a dual logo with comments at their meetings in Brazil and Washington - TheStandard C57.15-2009 was reviewed by the members of the TC14 committee and commentswere received from and documented from the member nations ( 14/637/DC ). Over all responsefrom the TC14 membership was very positive.

Paul Jarman said that now the IEC will decide on the approach that needs to be taken to makethis standard more IEC friendly. The first try will leave the document as is, then if needed basedon feedback from TC 14, a joint review team would be set up from IEEE and TC 14 to harmonizedocument further for use in IEC community. Comments received from the Great Britain, Italy, andJapanese delegations may require an addendum or such in an IEC Dual document if the maindocument is acceptable to TC 14 committee. Responses to these comments on terminology andTemperature Rise Limits (IEC 60076-2) will be addressed and given to the Technical Committeefor review before the TC14 Beijing Meeting in November.

C57.15-2009 standard has been available to the industry since the first of the year. No commentsor concerns were brought up by the members or guests on the use of this document.

TF – Transformer Efficiency and Loss Evaluation (DOE) – Phil Hopkinson reported.

The Task Force on Dielectric Transformer Efficiency and Loss Evaluation (DOE Activity) wascalled to order at 3:15 PM. There were 70 attendees, 26 members, and 44 guests with 5requesting membership. A quorum was present. There were no patents to disclose. The Minutesfrom the March 9, 2010 meeting in Houston, Texas, were approved as written.

1. Mr. Hopkinson reviewed slides from his presentation titled “Distribution Transformer EnergyEfficiency Task Force.” The presentation is posted on the IEEE Transformer CommitteeWebsite under the Distribution Transformers Subcommittee.

1.1. MVDT and Liquid-immersed transformers

Current DOE energy efficiency rules are stringent, falling between TSL-4 and TSL-5 for

TSL-1: The NEMA TP 1 standard level TSL-2: 1/3 of difference between TP 1 and minimum LCC (TSL-4) TSL-3: 2/3 of difference between TP 1 and minimum LCC (TSL-4) TSL-4: Minimum LCC (Life-Cycle Cost) TSL-5: Maximum energy savings with no change in LCC TSL-6: Maximum energy savings



Environmental groups did not feel that the efficiency levels were stringent enough and filed alawsuit against DOE on the grounds that carbon was not adequately monetized in therulemaking. A settlement was reached to open the rulemaking process earlier, though theeffective date for the new rules would remain unchanged. Dates for the DOE Rulemaking asa result of lawsuit settlement:

NOPR October 2011 Final Rule October 2012 Effective date 1/1/2016

Lawsuit settlement by the environmentalists requires review of efficiencies by October 1,2011. Standards may be raised or left unchanged. Standards can never be lowered ordropped (no backsliding).

Preliminary Analysis for the ANOPR is being conducted by Navigant Consulting, LawrenceBerkeley Lab and others. They are exploring issues such as cost of materials, loading andenergy costs, market size, best technologies, design optimization, amorphous core, electronictransformer, hexaformer technology and others. Their Findings are estimated to be releasedby 1st Q 2011.

1.2. LVDT transformers

Last updated in 2006 and based on NEMA TP-1. DOE has 6-7 year review requirement.Attempt underway to synchronize LV publications with MV and estimated to be released by1st Q, 2011. NEMA Premium Efficiency is one option to consider.

1.3. IEC Standard for Energy Efficiency

It was noted that the IEC TC14 is starting to address energy efficiency for distributiontransformers. It will be discussed at their next meeting November 2010 in Beijing. MichelSacotte of France will be the Convener (working group leader). Work will address MediumVoltage Liquid and Dry and is will be based on existing standards. Working Group delegatesfrom the US are being solicited. Contact Phil Hopkinson if you are interested.

2. New Business


The next meeting is planned for the spring in San Diego. The meeting adjourned at 4:33 PM.

Reported by: Scott Choinski, October 26, 2010.

TF – Tank Pressure Coordination – Carlos Gayton reported.

Carlos opened the meeting at 3:15 PM on Monday October 25, 2010, in the Tom Thomson Roomof the Toronto Hilton; introductions were made, and the attendance rosters were circulated. Nonew patents were disclosed. Quorum was reached with 15 of 26 members present.

The minutes of the spring 2010 meeting were presented and a motion was made by Ron Staharaand seconded by Alan Wilks to approve the minutes. Motion passed unanimously.

Carlos then presented a document with the report of the progress of the Task Force. Thedocument contained a summary of:

1) Agreements from the last meeting

2) A proposal for a standardized text for Tank Withstand and PRV Requirements, and

3) Status report on documenting the history behind tank strength and PRV requirements for futurereference.

Regarding item 1), even though on the last meeting it was agreed that this Task Force would befocused on covering the static pressure requirements, Marcel Fortin made comments at thepadmounted transformers working group meetings in Toronto, about revisiting the evaluation forthe potential adoption of dynamic pressure requirements for padmounted transformers. It was



agreed at these meetings that this Task Force would include this subject as part of its future workto be addressed once the work underway on static pressure requirements is completed.

On item 2), the summary of the progress made since last meeting was:

- A proposed standardized text was presented for the PRV requirements, trying to resolve severaleditorial and unit notation inconsistencies. This proposal was based on C57.144-2004, IEEEGuide for Metric Conversion of Transformer Standards

- Regarding Tank Withstand and PRV Requirements, a summary of the research made waspresented, and among the main conclusions, it was noted that after the proper consideration wasmade of the main factors involved to calculate the internal pressure on distribution transformers,such as oil expansion, pressure and temperature conditions on the oil and the gas space, and thesolubility of the gas in the transformer oil, the actual calculated and measured pressure valueswere significantly lower than those that would otherwise be calculated by only using the Gas Lawand ignoring the effect of gas solubility. Also, that the accurate equations were available forcalculation of the internal pressure on transformers with these considerations, and that thosepressure values were consistently below 49 kPa(gage) (7 psig).

Therefore, the present requirements of 49 kPa(gage) (7 psig) for tank withstand withoutpermanent distortion and cracking pressure for the PRV of 69 kPa(gage) (10 psig) wereconsidered to be adequate, since the main purpose of the PRV was to prevent an unsafecondition of the transformer static pressure due to either sustained overloading, or because of ahigh impedance internal fault.

Regarding item 3), a course of action was proposed as the next steps for review during the nextspring meeting in San Diego. Steve Shull made the motion to approve for the TF to complete theinformative annex of the history of tank strength and PRV requirements. This motion wasseconded and it was approved unanimously.

Carlos appointed Justin Pezzin to the role of Secretary of this Task Force.

Near the end of the meeting there was some discussion about whether the PRV flow specified inthe standards would be adequate for the larger distribution transformers. Steve Shull commentedthat this meeting was still discussing only the static pressure failure mode at the moment, and thatthe dynamic pressure failure mode will be discussed after this portion of the TF work has beencompleted.

As an additional topic for the next spring meeting in San Diego, Marcel Fortin will make a 15minute presentation of a summary / review of the current internal arcing fault test protocols andtheir applications.

The meeting was adjourned at 4:15 PM

There was no other Old Business.

Under new Business, Carlos Gayton wanted to make the subcommittee aware of a discussionconcerning C57.12.90 Section 11.0. He said a request that a survey of temperature tests bedone of the distribution transformer manufacturers and that the subcommittee be aware that thethere were a number of changes in this document that could drastically affect the heat run test ofa distribution transformer. Marcel added there are many sections that will be revised and eachshould be looked at by the Distribution Transformer Subcommittee members but specifically theproposed back to back temperature testing method.

Ali Ghafourian reminded everyone that a Task Force for wind power transformers is currentlymeeting under the auspices of the Power Transformer Subcommittee. He recommends it bemoved to the Distribution Subcommittee. He was concerned that the IEC document that the TaskForce is proposing to use may not completely describe this product. He strongly encouraged thegroup to review the IEC standard that is being proposed for use by this group. Phil Hopkinsonbrought up that there are very subtle differences between class 1 power transformers anddistribution transformers but he feels that the application tends to make the transformer fit in thePower Transformer classification. Steve added there are other issues including over-voltage and



harmonic content that have to be considered and this group may need to be part of thePerformance Subcommittee. Marcel responded to Phil comment regarding the distinctionbetween a Distribution and a Power Transformer by asking where the distention between the twocould be found. Steve replied that even though there are definitions in C57.12.80, the question ofwhere this Task Force should be place will be decided by the ADCOM committee. Gary Hoffmanstated C57.12.80 needs to do a better job in stating these definitions and invited all interested toattend the Standards Subcommittee meeting.

There were no additional new items.

The meeting adjourned at 10:35am.

Dielectric Tests Subcommittee – Unapproved Meeting MinutesOctober 27, 2010-Toronto Ontario

F10 Dielectric Tests Subcommittee Page 1 of 8

9.6 Dielectric Tests Subcommittee – Loren Wagenaar, Chair; Thang Hochanh, Vice-Chair; Dennis Marlow, Secretary

9.6.2 Working Group Reports

9.6.2.1 Task Force on External Dielectric ClearancesEric Davis, Chair; Dennis Marlow, Secretary

The TF met on Oct. 25, 2010 at 9:30 am at the Hilton Toronto. 48 people attended this sixthmeeting, 8 members and 40 guests (19 repeat guests) were present with 2 accepted as newmembers, bringing the total membership to 20. We did not have a quorum. The membershiplist will be verified further to include only those participants who have attended 2 of the last 4meetings.

The minutes from the fall 2009 meeting in Lombard, IL and the spring 2010 meeting inHouston will be sent to the active members for approval by email.

The IEEE patent disclosure requirement policy was discussed. Reference to the packageposted on the IEEE Transformers Committee Web site was made. None of the members andguests present during the meeting was aware of any patents related to the work of this TF.



The Chair adopted a different approach for this meeting in order to get informal input from theattendees about the clearance requirements and obtain any feedback about any problemswith the present clearances being used in the industry.

The following points were discussed:

Recommended minimum electrical clearances based on BIL/BSL requirements versusclearances required for applied and induced tests. A straw vote was conducted with30+ to zero in favor of making the clearances based BIL/BSL.

Presentation of the recommended minimum electrical clearances. The current tablelists clearances by voltage. A straw vote was conducted in favor of listing theclearances by BIL/BSL. There were different opinions on including the voltage as well.

Establishing the clearances for BSL.

o The clearances in C57.12.00 are less than those used in CSA or IEC for thesame BSL.

o IEEE 1427 determines recommended minimum clearances in air insulatedsubstations based on certain electrode conditions and configurations plus a10% probability of flashover.

S = 8 / [ (3400* kg * δm)/CFO -1 ]

S is the metal-to-metal strike distance in meterskg is the gap factor

δm

is the altitude correction factor (1.0 at sea level)CFO is the critical flashover voltage in kilovolts

o CSA also uses the same formula as that used in 1427.

A straw vote was conducted in favor of using this formula.

Selecting the gap factor. The gap factor is based on the physical configuration. It wasagreed to provide a list of gap factors along with a recommendation of the gap factor touse.

Selection of the CFO.

o The criteria of 10%, 20% or 50% probability of flashover were discussed.o A discussion evolved about what clearances are actually required for the

transformer. The question of insulation co-ordination done by the system planners is

beyond the scope of this TF but for the resulting BIL specificationrequirements for the transformers, it is extremely important that theexternal clearances have adequate safety margin to prevent externalflashovers.

The chosen surge arrester will determine the permissible safety marginfor insulation co-ordination.

AEP uses 20-30 inch clearances than IEEE clearances at 230 and 345kV. At 500 kV and above all transformers are single phase.



The system study done by the purchaser has specified what he has determinedto be the correct BIL for the transformer. Ultimately it is up to the customer todetermine this BIL and up to the transformer manufacturer to provide adequateexternal clearances to prevent external flashovers.

o We discussed the impact of a flashover at the transformer. A simple phase to phase flashover can burn a hole in the bushing cap

which can cause consequential damage to the bushing such as water inthe cap or in the oil.

A flashover at the secondary side for an autotransformer will result in athrough fault and that needs to be taken into consideration.

o The general consensus was that we do not want a flashover on the externalterminals. It is ok to have a flashover on the external incoming lines but not onthe transformer terminals.

o There was a suggestion to calculate what the probability of flashover is on thetransformer terminals with the CSA and IEC clearances.

A survey will be sent out to the members and interested guests plus the DI SC for review sothat comments can be obtained about the proposed clearance table.

As time was short the meeting was adjourned at 10:47 am.

Respectfully submitted, Dennis Marlow

9.6.2.2 Task Force on Special Dielectric Test Issues – Bruce Forsyth, Chair

The Task Force on Special Dielectric Test Issues did not meet as their assigned work iscompleted.

9.9.2.3 Working Group for Revision of the Impulse Test Guides C57.98 and C57.138Art Molden, Chair; Joe Melanson, Co-Chair

1. The meeting started at 9:30 AM on Tuesday October 26, 2010, with 44 attendeespresent of which 7 were members and 37 were guests. Introductions were made ofthe attendees.

2. The quorum requirements were discussed and the member statuses of activemembers in the group were confirmed by Chairman Art Molden. Based on themembership requirements specified in the WG P&P manual our working group nowhas 9 members.

3. Having established that a quorum of members was present past meeting minuteswere offered for approval and approved.

4. The IEEE Patent Policy policies were reviewed with the group. The group was polledto see if there were any known patent issues to disclose relative to this standard.None were indicated by any of the attendees.



5. Art Molden announced that our Guide was in the balloting process and there wasgoing to be some more work to do to resolve comments that were being posted.

6. Art asked for volunteers to sign up for participation in the revision of C57.138 theRecommended Practice for Routine Impulse Test for Distribution Transformers. Asignup sheet was circulated and 18 attendees of our WG signed up.

7. An item of new business was proposed by Pierre Riffon regarding the so called “kfactor” method of measuring impulse voltage waves. The “k factor” method will beincluded in the next revision of IEEE Standard 4 that is currently in the editorial stageprior to the first ballot. Art Molden along with Standard 4 WG members Jim McBrideand Jeff Britton and also Dr Wolfgang Hauschild provided some history andexplanations on how this method differs from the present method of determining theimpulse voltage parameters from a digital record of the impulse voltage. Art Moldenwill investigate the possibility of posting some technical papers on this topic on theTransformers Committee web site. It was also suggested that this topic might be agood one to use as a Presentation at a future IEEE Transformers Committeemeeting.

There being no more business and the meeting was adjourned at 10:15 AM.

Minutes submitted by Art Molden and Joe Melanson

COMMENTS FROM SC MEMBERS

Marcel Fortin indicated that someone from the Distribution SC has been assigned to reviewC57.138 by the Distribution SC. Loren Wagenaar indicated that it is the responsibility of theDI SC to perform that function since the work on the recommended practice was theresponsibility of the DISC, and that any and all members from the Dist SC are welcome tojoin the WG for the review of this standard. He indicated that the Dist SC chair had given himthe name of a volunteer from the Dist SC and he would contact that person beforeannouncing him to the committee.

9.6.2.4 Working Group on Revision of Low Frequency Tests – Bertrand Poulin, Chair;Bill Griesacker, Secretary

1. The WG met on October 26th. There were 63 attendees, 21 members and 42 guests

present. There are 53 official members of the working group, therefore there aquorum was not present to permit voting.

2. The minutes from the October 2009 meeting in Lombard, IL were brought to the table;there were no objections although the minutes were not approved since a quorumwas not present. The minutes will be distributed by e-mail to the members forapproval.

3. There was a request for any patent issues to be made known, none were voiced.

4. The chairman announced that the tutorial on partial discharge (pd) requested byattendees at a previous meeting will take place at the 2011 Fall meeting.



5. Thang Hochanh presented his report for the Task force for pd in other devices suchas CTs and Bushings. At their meeting, 3 presentations were made. The topicsdiscussed were the construction, shielding and grounding of a High Voltage laboratoryto achieve very low background noise for pd testing and typical test configurations forthe testing of PTs and CTs. More details are can be found elsewhere in the DISCminutes.

6. The chairman made a quick presentation on special situations to be considered whenmaking a C-tan(d) test (also referred to as dielectric power factor) on transformers. Inparticular, the case of transformers having axially split LV windings should be testedas 2 winding transformers and not as 3 winding ones. The widely used 0.5% limit forthe power factor applies to main insulation structures made of oil-barriers or paper oilsystems. Insulation structures mostly made of solid insulation may show a slightlyhigher power factor without causing any concern. The attendance agreed that acaution note should be added to the factory test code and the field test guide on thistopic. A comment from a member at the SC meeting was that you also need to look atthe current and capacitance when you have power factors like 0.65 or 0.7

7. Dr Lemke presented the state of the development work on an addendum to the IECstandard on pd measurements. Several important additions are under consideration.

8. Loren Wagenaar inquired about the follow-up to the results of a survey sent to the SClast year on the testing of 69 kV transformers. The status is that the WG has alreadyagreed to recommend that 69 kV power transformers must receive impulse andinduced test as class II transformers. The recommendation will be sent to theChairman of the WG on revision of C57.12.00 for inclusion in the next ballot of thisdocument as it was too late for inclusion in the 2010 revision.

9. The meeting adjourned at 2:45 p.m.

9.6.2.5 Working Group on Revision of Impulse Tests – Pierre Riffon, Chair;Peter Heinzig, Vice-Chair

The WG met on October 26, 2010, from 3:15 pm to 4:30 pm. Twenty members (20)members and fifty-eight (58) guests attended the meeting. Required quorum was met. Four(4) guests requested membership. The meeting was chaired by Pierre Riffon, chair of theWG.

WG chair has reviewed the WG membership since the Houston meeting. The membershiphas been decreased from 42 members to 32 members. Members should have attended atleast one of the two last meetings. Otherwise, their member status has been changed to aguest status. Only active members coming on a regular basis to meetings will keep theirmember status. This membership rule will be kept for upcoming meetings in order to getbetter chances to meet the quorum requirement.

The agenda has been reviewed and accepted as written.



The minutes of the Lombard and Houston meetings were approved as written. Lombardmeeting minutes were not able to be approved at the Houston meeting since the quorum wasnot met.

The IEEE patent disclosure requirement policy was discussed. None of the members andguests present during the meeting were aware of any patents related to the work of this WG.

The first technical item of business was to discuss the status of Revision 4 of the draftconcerning the tap changer position during lightning impulse tests. This subject has beenextensively discussed at the past 4 meetings. The 3

rdsurvey made within the WG and within

the Dielectric Tests SC got an approval rate of 88%. Four (4) negatives were received, 2were resolved and 2 cannot be resolved. This bring the approval rate of the 3

rdsurvey to

92.7%. Since the two negatives cannot be resolved, the WG chair did recommend to sendD4 to Steve Antosz for inclusion in the next C57.12.90 draft for ballot. This recommendationhas been approved by 19 members present. One member did vote against the proposal.

The second technical subject was related to the survey made on the number of impulses tobe applied during impulse tests. The proposal requests to increase the number of fullimpulses from one to three as required by IEEE and IEC standards on insulation coordinationand HV testing and to align the impulse testing procedure with IEC 60076-3. This survey wasmade in February 2009 and the comments received were not really discussed due to lack oftime and overburden agendas. WG Chair proposal was to re-survey the proposal prior to thenext meeting within the WG and Dielectric Tests SC taking into account the commentsreceived on the first survey.

On new business, a presentation by Mr. Luc Doorpmanns regarding the F filtering function tobe applied on lightning impulse wave shape for parameters evaluation. This filteringrequirement is now part of the newly published IEC 60060-1 on dielectric testing. IEEE Std. 4is also considering of adding this method in the next revision of IEEE Std. 4. This will alsoimpact transformer impulse testing and the WG will consider it when the new edition of IEEEStd. 4 will be published.

The meeting adjourned at 4:00 pm on October 26, 2010. Pierre Riffon P. Eng. WG Chair

COMMENTS FROM SC MEMBERS : Baitun Yang, Pennsylvania Transformer indicated thatthe proposed requirement for impulse testing on various tap positions may not impose thehighest stress on the windings and that there should be some freedom to test on otherpositions. He will clarify his comments with the SC secretary by email.

9.6.3 Liaison Reports

9.6.3.1 High Voltage Test Techniques (HVTT), IEEE Standard 4 - Arthur Molden

The Working Group for the revision of IEEE Standard 4, Standard Techniques for HV Testingmet here in Toronto on Thursday and Friday October 21

stand 22

ndlast week. There were 9

members present.

The editorial work on the main body of the standard is just about complete but work still hasto be done on four annexes that will be included with the standard.

As mention in past reports this revision of Standard 4 has been extensively rewritten andrearranged. The major topics covered by this standard are the same as those covered inearlier editions but the content has been revised and made more tutorial in nature.

Of the revisions made the one that will have most impact on our test procedures will be theadoption the “k-factor” method of measuring the parameters of impulse voltage wave formsthat have oscillations on the peak. For those interested in obtaining information on thismethod I have a number of technical papers that provide some background on the topic. I willrequest that a couple of papers be placed on the transformer committees web site and letyou all know when they become available to download.

Respectfully Submitted: Art Molden.

COMMENTS FROM SC MEMBERS

Loren Wagenaar noted that the new method of analysis of the oscillations on theimpulse wave is being changed by both IEC and IEEE. Thus, it may be appropriate that aseminar be presented concerning the methodology for this new technique since it will affectall manufacturers and users.

Pierre Riffon questioned if there also were some minor changes to the atmospherecorrection factors in the new IEC 60060-1 and IEEE Std. 4 documents. Jim Britton indicated



that Std 4 will comply with the IEC document and that equations will put in the standard aswell as the curve.

9.6.4 Old Business

There will be a tutorial on PD measurements at the Fall 2011 meeting.

9.6.5 New Business :

1. At the PORTO meeting it was proposed by Bruce Forsyth to have a tutorial aboutsteep front of wave testing and what needs to be done to protect the transformerand substation for steep front impulse waves. Bruce now indicates that this is notnecessary and that an annex has been included to C57.12.90 to include testvalues for various BIL levels.

2. Phil Hopkinson indicated that HV steep front transients may be a requirement inthe future but is not needed at the present time.

3. Peter Zhao indicated that some universities are studying the steep front impulsetransient wave problem and that we may need to consider this in the near future

NO MOTION was received from the membership with regard to these issues.

MINUTES OF THE MEETING OF THE HVDC CONVERTER TRANSFORMERS &SMOOTHING REACTORS S.C. IN TORONTO, ONTARIO, OCTOBER 26, 2010

On October 26, 2010, the HVDC Converter Transformers and Smoothing Reactors S.C. metat 1:45 p.m., in the Johnston Meeting Room of the Hilton Downtown Toronto Hotel, inToronto, Ontario. There were 12 members and 21 guests present. The total membership ofthe SC is 24, but includes 3 corresponding members. Therefore there was a quorum. Thefollowing are the highlights of the meeting:

1. Introductions were made and the attendance list circulated.

2. The minutes of the Houston, Texas meeting were approved.

Note: The minutes of the Toronto SC meeting will not be approved until the SCmeeting in San Diego.

3. IEEE patent policy was reviewed and no issues were raised.

4. The Chairman provided a synopsis of the Administrative SC meeting.

5. The Chairman reported that the revision of IEEE 1277 had been published. Hethanked SC members for their help.

6. Mario Schenk made a PowerPoint presentation on his company’s experience with 800kV HVDC in China. This presentation will be posted on the Transformers Committeewebsite with the minutes. The presentation provided part of the basis for ensuingdiscussions on future work of the SC.

7. Key discussions points on future work of the SC; especially future revisions of IEEE1277 and IEEE C57.129 were:

i) In future revisions of IEEE 1277 and IEEE C57.129 material for 660 kV and800 kV should be expanded, including test code.

ii) Should test voltages for the dc tests be standardized?iii) Should information on field tests be included? The Chairman pointed out that

SFRA testing was an option used by some utilities. IEEE C57.152 (field testguide) could also provide information. Testing of oil conductivity could also bea good field test.

iv) What BILs should be used for 800 kV?v) Are there any test equipment limitations at 660 kV and 800 kV?vi) Should dielectric test levels for 660 kV and 800 kV be based on standard

margins vs standard levels?vii) Should more informative tutorial information be included?

2

viii) Some questions were tabled for future presentations/discussions. Whathappens if an 800 kV link is lost vs. the loss of a 500 kV link? Why is 660 kVor 800 kV used vs. 500 kV; cost or the bulk power transfer capability?

ix) Is this polarity reversal test as it is now in the standard sufficient?

The Chairman requested that SC members prepare presentation material on futurework for the San Diego meeting as a basis for discussion.

The meeting adjourned at 3:00 p.m.

9.8 C57.13 Instrument Transformers – R. McTaggart –Unapproved Minutes

Chair’s Remarks & Announcements

The Instrument Transformer Subcommittee met on Wed Oct 27 at 8:00AM for a double session.

8 of the 12 members plus 19 guests attended.

The previous meeting’s minutes were approved as written and there wereno Patent issues.

The past Chair, Jim Smith, recently resigned as SC Chair after 17 years –appreciation and best wishes were expressed by all

The next meeting is scheduled for Apr 10 – 14, 2011 in San Diego

The structure and privileges for members of different organizations withinIEEE were reviewed in response to some misunderstandings in theprevious meeting

The status of all C57.13 standards was reviewed

9.8.1 Working Group for Revision of IEEE C57.13 Instrument Transformers

This working group will meet officially for the first time in a separate time slot at the SanDiego meeting. Many of the people who will be members were in attendance at the SCmeeting and discussed the timeline and goals of the WG. It was agreed that significantwork would need to be done between meetings to meet the deadline. It was pointed out,however, that we should not let the quality slip to meet the deadline and a PAR extensionmay be necessary.The most important issue discussed was the dilemma of how to handle differencesbetween C57.13 and C57.13.5. Some suggestions were:

1) Limit the scope of C57.13 to Instrument Transformers below 115 kV anduse C57.13.5 for all Instrument Transformers 115 kV and above. Thiswould mean revising both standards.

2) Make the C57.13.5 requirements mandatory for all InstrumentTransformers 115 kV and above. This has the same effect as 1) but canbe accomplished by only revising C57.13 and including reference toC57.13.5 for test requirements where applicable.

3) Define 2 classes of Instrument Transformers – one which meets C57.13.5as well as C57.13 and one which only meets C57.13. This suggestion(similar to Breaker standard) resulted in the most discussion. If this optionis chosen it can also be accomplished by only revising C57.13 andincluding reference to C57.13.5 for test requirements where applicable. It

would define 2 classes, say Class 1 & Class 2 with Class 2 having theoptional test requirements as per C57.13.5. Class 1 would be the defaultto be assumed by the manufacturer if no Class is specified.

It was suggested that a survey on this subject should be done before the next meeting butto ensure that all WG members have the opportunity to vote this was deferred to the 1st WGmeeting.

9.8.2 Review of Survey Responses

1) Bushing CT Proposal – 75% were in favor of including the appendix and55% were in favor of it being normativeR. Mullikin to provide new draft

2) CT Metering Accuracy Calculation Proposal – 55% were against having aseparate clause and 89% were against replacing 8.1.7 to 8.1.10The comments indicated that the proposed clauses should beconsolidated with the existing ones.V. Khalin to work on this

A verbal presentation of testing of the sample CTs provided by Triacta was given byVladimir Khalin, ABB Inc. These CTs were tested down to 8mA secondary output. Thetransformers were found to be very accurate in the range tested. Vladimir stated aconcern about the potential for error in the mA CT secondary circuit if the wiring is nottwisted and shielded pair to protect against electric field influence. Further investigationwill be conducted on this point.

A presentation was also given by Dr. Eddy So of the National Research Council ofCanada outlining the methodology of determining the true accuracy of currenttransformers in 80mA and 100mA range. Details of how the test is set-up were givenand included some of the theoretical points. Specific attention was drawn to thepossibility that voltage influences may cause ratio errors. More testing would have to bedone in this area to confirm whether this is the case.

The WG Report Given at the Sub-Committee Meeting:

WG report was presented by Vice-Chair Claude Beauchemin. The WG met on Tuesday, October 26 and Wednesday, October 27. A quorum was achieved at both sessions.

The Data and Case Studies TFs gave status updates on their activities. Norman Field reported that the Data TF has collected over 600,000 data samples for more than 150,000 transformers and are now working on sorting the data by class of transformer to determine the effect, if any, of oil volume. The TF is requesting data on Network transformers be submitted.

Paul Boman reported that the Case Studies in the Guide are meant to illustrate the analysis methods that can be used. He indicated that we would need to be careful in the use of color photographs that may not reproduce well in black and white. There may also be copy write issues that will need to be researched for this section of the Guide.

Fifteen proposals for were presented to the WG on various aspects of the Guide, such as Table 1 and the number of conditions (3 or 4) and whether they should be numbered or labeled as normal, caution, and warning. Eight of the 15 proposals were voted on. Details on the various proposals and discussions can be found in the detailed minutes.

Approval of minutes from the Fall 2009 Lombard, Illinois the Spring 2010 Houston, Texas meetings was requested. Both minutes were approved as written.

The IEEE Patent disclosure requirements were discussed and a request was made for disclosure of any patents that may be related to the work of the WG. There were no responses to the request for disclosure.

Report of work done since last meeting:

Rick Ladroga gave a recap of the chairs of the various TFs that have been initiated.

1. Arc Furnace – Chair Tom Lundquist 2. Framework – Chair Jim Dukarm, Vice-Chair Dave Hanson 3. Data – Chair Norman Field, Vice-Chair Pierre Feghali 4. Case Studies – Chair – Paul Boman, Vice-Chair Arturo Nunez 5. Diagnostic Methods – Chair Michel Duval, Vice-Chair Dave Wallach 6. Bibliography – Chair Jerry Murphy, Vice-Chair Tom Prevost

A group met to work on the Guide in Stowe VT on August 12, 2010. Teleconference meetings were also held on September 10 and October 1 of 2010.

Task Force reports:

1. Arc Furnace – Chair Tom Lundquist

Nothing more to report at this time.

2. Framework – Chair Jim Dukarm, Vice-Chair Dave Hanson

Nothing to report at this time.

3. Data – Chair Norman Field, Vice-Chair Pierre Feghali

Data has been provided. Over 600,000 data samples for over 150,000 transformers have been received for analysis. Work to clean up the data is being done before analyzing it can be done. They hope to have concentration and ratio limits available for review prior to the San Diego meeting. The transformers making up the database are anywhere from 0.5MVA to over 500MVA in size.

T. Prevost: Size matters. How much of the data has the transformer size included in the data? Norman indicated that most of the data includes the transformer size.

J. Thompson: The present guide has no distinction based on volume of oil. Norman indicated that they intend to sort the data by different classes to help determine the effect of oil volume. Approximately 32,000 samples representing 10,000 network transformers are included in the data that has been received.

L. Cheim: Laboratory variations need to be taken into account on the data.

P. Zhao: What is the test environment? Beauchemin indicated that primarily the data is from utility DGA analysis sampled by utilities and performed by laboratories.

4. Case Studies – Chair – Paul Boman, Vice-Chair Arturo Nunez

Paul presented a case study for a turn-to-turn fault. The case study shows how the various analysis methods are applied with a walk through guide for users. He requested input from others that could also be used for additional case studies.

Paul indicated that while we can include photos for the case studies in the Guide, we will need to be careful in putting photos in the document that will not reproduce well in black and white.

T. Prevost: There may be copy write issues that will need to be researched and provided.

P. Zhao: Will there be any attempt to show case studies for units that have failed without any gassing evident or what percentage of units may fail without any gassing? P. Boman indicated that the case studies are meant to illustrate the analysis methods that can be used not to indicate the likelihood of whether a unit will fail or not fail based on the levels of gassing.

5. Diagnostic Methods – Chair Michel Duval, Vice-Chair Dave Wallach

No report.

6. Bibliography – Chair Jerry Murphy

No report.

Propositions for WG vote:

The following proposals were sent out to the WG members recently for consideration and presented at the meeting for vote.

1. This proposal refers to section 4.2 “Oil decomposition”

It is proposed to remove the Halstead graph (actual Figure 1 “Halstead’s thermal equilibrium partial pressures as a function of temperature”) and replace it with the Rogers graphs on relative gas generation rate (as illustrated below).

Result: A motion was made and seconded to approve this proposition. There was minimal discussion by the WG membership. Proposition 1 passed.

2. This proposal refers to section 6.1 “General”

It is proposed to add a section discussing the reliability and accuracy of DGA results in general and especially at low gas concentrations and rates.

A motion to approve the above proposal was made and seconded.

Discussion & Vote:

A question was asked as to the variation with temperature as the gas moves in and out of the head space would be included in this section. All of the sources of variation would be included in the section. Information from ASTM D27 should be included. Marc Cyr agreed to help with the ASTM D27 information.

A modification to the motion was made that this working group will enlist ASTM D27-03 to assist in accomplishing this.

Proposition 2 passed as amended.

3. This proposal refers to Table 1 “Dissolved Gas Concentrations” in Section 6.5 “Evaluation of transformer condition using individual and TDCG concentrations”

Note: Revised value for this table will be based on rigorous statistical analysis of all the DGA results supplied to the WG data analysis TF. Every participant is strongly encouraged to supply its own data set for this effort.

It is proposed to modify “Table 1” “Dissolved gas concentration” to contain three (3) conditions, with 2 limits, (as opposed to the present 4 conditions with 3 limits) and to give a name to each condition (Normal, Caution, Warning) rather than use numbers (condition 1, 2 and 3).

Discussion & Vote:

How did the 13 people that responded electronically vote. The 13 electronic votes were all in favor. Question was asked if there is a table available for review. The response was that not at this point. This table is intended for first time test of a unit only to give guidance without a false sense of security based on a single test.

D. Platts indicated that he would be concerned using strictly a statistical analysis along with cautions or warnings. There would be potential legal concerns with the use of “warning”. He suggested that we use numbering rather than words such as caution or warning.

The first meeting session was adjourned at this point at 4:30PM, Tuesday, October 26.

The second meeting session was opened at 9:30AM, Wednesday, October 27.

L. Cheim: If a number system is used, then what will be the definition of a level 3? The word warning should not then be used in the definition.

D. Sundin: Use a comparison to a population. R. Ladroga: simple directions need to be provided.

J. Graham: Need to clearly define what is meant by the normal, caution, and warning.

R. Thomson: Normal, Caution and Warning carry more prior meaning than a Condition 1, Condition 2 or Condition 3 would.

T. Lundquist: Indicated that the wording with Normal, Caution, and Warning was used in a previous Draft of the last WG document and that it seems to be appropriate for a first test on a unit.

The proposal was modified and split into two separate motions. A first motion was made as follows:

Modify “Table 1” “Dissolved gas concentration” to contain three (3) conditions, with 2 limits, (as opposed to the present 4 conditions with 3 limits). The new motion to move from four to three condition levels was passed.

A second motion was made as follows:

Modify “Table 1” “Dissolved gas concentration” to use numbers (condition 1, 2 and 3) rather than Normal, Caution, and Warning. The motion passed as proposed.


It was proposed that the limits between the “1” and the “2” conditions will be the DGA data set 90% percentile values, or another accepted statistical limit if proven effective, for each gases and TDCG, as derived from the analysis of the supplied DGA data.

Discussion & Vote:

J. Thompson: Suggested changing the words “would be” to “will be considered”.

L. Cheim: There should be a set statistical limit.

J. Dukarm: In the event that the statistical result is clearly not practical, then there needs to be an ability to make an engineering based determination.

D. Platts: reiterated his concern with using statistical information.

T. Prevost: We need to use statistics since there are not enough case studies or data from case studies to be able to come up with data any other way than by using statistical analysis.

D. Sundin: Indicated that the lowest limit should be the detection limit. There is no theoretical 0 value in statistics.

An amended motion was made to the following:

It was proposed that the limits between the “1” and the “2” conditions will take into consideration the DGA data set 90% percentile values, or another accepted statistical limit if proven effective, for each gases and TDCG, as derived from the analysis of the supplied DGA data.

The motion as amended was passed with 24 in favor.


It is proposed that the limits between “2” and “3” will take into account an accepted statistical limit, or a higher percentile value (e.g., 95% or 98%) if standard statistical limits prove to be inconclusive, that can be shown to be sufficiently similar on different populations and to be actually representative of a “3” condition, as derived from the analysis of the supplied DGA data.

Discussion & Vote:

A motion was made to accept the above proposition. The motion was passed with 29 in favor.

6. This proposal refers to Section 6.5 “Evaluation of transformer condition using individual and TDCG concentrations” and to Section 6.2 “Determining combustible gas generating rate”

It is proposed to add a new Table (Dissolved gas rates) with individual gas generation limits (change over time), similar in its construction to Table 1.

Discussion & Vote:

T. Prevost: Made a motion to accept the proposal. The motion was seconded.

J. Crouse: Indicated that on individual samples there is variation based on methods of sampling etc and this should be included. C. Beauchemin indicated that he agreed and that this would need to be described.

The purpose of the Guide is to produce a document that can be easily interpreted. What does an experienced person do when he gets a sample that is unusual? He takes another sample. Details of trend analysis need to be included.

The motion was voted on with 1 negative the remainder voted affirmative. The motion passed.

7. This proposal refers to Section 6.5 “Evaluation of transformer condition using individual and TDCG concentrations” and to Section 6.2 “Determining combustible gas generating rate”

It is proposed, that when a valid fault diagnostic is obtained, to suggest adjustments to values in Tables 1, and in the proposed new Table (dissolved gas rate), based on the nature of the fault, its activity or its location (in paper or oil).

Discussion & Vote:

T. Lundquist made a motion for vote on the above proposal. The motion was seconded.

T. Prevost indicated he is opposed to the proposal.

M. Duval explained that the gas limits in Table 1 are average values that don’t take into account the location and duration of a fault. Rick indicated that perhaps an informative annex would be appropriate.

J. Graham: Suggested that there needs to be some logical thought into the location of the fault. He agreed that this would be more appropriate to an informative annex.

A vote was called. There were no votes for the motion. The motion failed.

8. This proposal refers to Section 6.5.1, “Determining the transformer condition and operating procedure utilizing TCG in the gas space” and Table 2 “Action based on TCG”

It is proposed to remove Section 6.5.1 describing interpretation of gas phase analysis results with its associated Table 2 (actions based on TCG). An alternative would be to move it to the Annex (Informative) section.

Discussion & Vote:

A motion was made and seconded as amended below:

It is proposed to remove Section 6.5.1 describing interpretation of gas phase analysis results with its associated Table 2 (actions based on TCG).

Discussions indicated that maybe complete removal should not be done, but that it could be moved to an annex.

A vote was taken as amended with 5 for and 18 against. The motion failed.

A motion was made as follows:

It is proposed to remove Section 6.5.1 describing interpretation of gas phase analysis results with its associated Table 2 (actions based on TCG) and create a section on TCG (head space) interpretation in an Annex.

The vote was unanimous in favor of the amended motion.

The meeting time expired before the remaining proposed motions could be discussed. Additional web based meetings will be looked at as an option to keep the momentum moving forward on the Guide. The remaining proposals are provided below for information purposes only and were not voted on.

9. This proposal refers to Section 6.5.2 “Determining the operation procedure and sampling interval from the TDCG levels and generating rates in the oil” and Table 3 “Action based on TDCG”

It was proposed to recommend the installation of on-line monitoring to replace high frequency sampling (e.g., < weekly) or for transformers considered dangerous (zoned).


It was proposed to add a safety warning for work performed on potentially faulty transformers, as indicated by DGA interpretation.


It was proposed to modify Table 3 (“actions based on TDCG”) to include individual gas rates (as defined in the new Table) and concentrations (from Table 1).

12. This proposal refers to Section 6.6 “Evaluation of possible fault type by the key gas method” and Section 6.7 “Evaluation of possible fault type by analysis of the separate combustible gases generated”

It was proposed to use the following diagnostic methods: Key gas, Rogers, Duval Triangle 1 and IEC 60599 (Section 5.2 and 5.3). All other methods, existing in the guide or proposed, should be in the annex section (Informative) (e.g., Doernenburg, Duval Triangles 4 and 5 for low temperature faults…).

13. This proposal refers to Section 6.6 “Evaluation of possible fault type by the key gas method” and 6.7 “Evaluation of possible fault type by analysis of the separate combustible gases generated”

It was proposed to add a section on the limitations of the various DGA analysis and diagnosis methods.

14. This proposal refers to Section 7 “Instrument for detecting and determining the amount of combustible gas present”

It was proposed to delete the description of gas monitors in Section 7, and to replace the monitor description with information relevant to the interpretation of monitor readings, when this interpretation is different from interpretation of laboratory results. (example: computing rate of change, taking into account detection limits, comparing results from two different sources…).

15. This proposal refers to Annex A “Bibliography”

Two possibilities were proposed for the bibliography. Note: the actual bibliography contains 176 entries, from 1928 to 1989, several of which could no longer be retrieved.

A) Extended bibliography containing all references, historical, up-to-date research and practical application (such as other standard) (probably 150 to 200 entries)

B) Only up-to-date bibliography entries, standard and application oriented references (probably less than 50 entries)

The second meeting was adjourned at 10:55 am.

7.3.3.2. IEEE Trial-Use Guide for the Use of Dissolved Gas Analysis Applied to Factory Temperature Rise Tests for the Evaluation of Oil-Immersed Transformers and Reactors WG Chair Jim Thompson


Chair Jim Thompson presented.

The WG met Tuesday afternoon, October 26. The PAR was approved in June of 2010 and will expire December 31, 2014.

The WG will be starting with the last version of the Guide (draft 18) that the previous WG left off with. Discussions included the limit of the document guidance to one per unit load during factory temperature rise tests, the values in Table 1 for Gas generation rate guidelines, the DGA sample time requirements, the IEC guide 61181, the requirement of no detectable acetylene gas in Table 1, and the bibliography.

The WG is looking for data.

7.3.3.3. IEEE C57.139 IEEE Dissolved Gas Analysis in Load Tap Changers WG Chair Fredi Jacob, Vice-Chair David Wallach, Secretary Sue McNelly


Presented by Dave Wallach.

The WG met Tuesday morning, October 26.

The document was initially balloted in November of 2009 and just recently completed a 3rd recirculation ballot. After this 3rd recirculation ballot, there were 2 negatives with comments and 5 negative ballots without comment. The BRG has reviewed and responded to the comments. The negative ballots were in regard to the inclusion of the safety warning regarding combustible gases in the LTC, not providing generic gas limits to the user, and the limit percentiles that were provided.

The ballot has been submitted to REVCOM for approval as there is presently a lack of sufficient information/data at this time to be able to provide generic limits. A PAR extension request has also been made to NESCOM in the event that further work is required after REVCOM has reviewed the document.

Susan McNelly indicated a special thank you to Matt Ceglia for his help with the ballot preparation and submittal process and to the WG ballot resolution group Fredi Jacob, Dave Wallach, Jim Dukarm, Claude Beauchemin, Shuezen Xu, Rowland James, Norman Field, and Mick Bayer

Presentation - Nomogram for looking at LTC-DGA data (Fredi Jakob and Jim Dukarm)

Fredi presented a nomogram for review that was developed by Jim Dukarm as a method of looking at the gas ratios. A paper that Jim has prepared will be made available on the WG webpage.

Presentation – Choice of percentile points (Jim Dukarm)

Jim Dukarm gave a presentation on the differences between LTC populations. He indicated that further work is needed to provide a basis for publishing numeric limits in the guide. First, the question, can generically usable limits be derived from a large database built from many sources, must be answered. Secondly, formal statistical tests will need to be done to determine if similar models of LTCs can be grouped together and treated as one generic type for purposes of deriving and applying limits.

Gas concentration caution limits, it is known that there is data from faulty LTCs in the database and that some faulty LTCs generate more combustible gas than healthy ones in the same population do. Most of the extremely high gas concentrations belong to faulty or highly stressed LTCS.

Looking at the gas concentration ratios, to calculate gas ratios, only samples where both gases are at least 10 ppm are used. Trace amounts of gas are not interpreted.

A comparison of methane, ethylene, acetylene distributions and ratios for four different utilities was provided with unexplained differences between them. The possibility of coming up with generic limits is not ruled out, but further evaluation would be needed due to the wide differences between these four utilities.

Jim’s presentation will be made available on the WG webpage.

The meeting was adjourned at 12:07pm.

7.3.3.4. WG PC57.637 Guide for the Reclamation of Insulating Oil and Criteria for Its Use WG Chair Jim Thomson, Vice-Chair TV Oommen


The WG met Tuesday morning, October 26 and a quorum was present.

The work on the Guide is progressing. Jim Thompson gave a presentation on the relationship/cross references of this Guide to other existing guides, particularly in regards to percent saturation of water in oil.

There was discussion about the C57.106 history in regards to the inappropriate application of equilibrium curves. There was also a discussion in regards to cold start warnings.

There was also a discussion on whether re-refined oil can be considered as new oil and where this fits within the Guide. The Guide’s scope presently indicates that the guide does not cover the use of oil in new apparatus under warranty.

The Minutes (unapproved) of the WG Meeting as Submitted:

The working group meeting was conducted at 8 am on October 26, 2010 at Toronto Canada with 23 people in attendance with 10 of the 19 current working group members present. This document was reaffirmed in 2007 and the PAR for revision was approved December 10, 2008. Working Group members Jim Thompson (chair) and TV Oommen (vice-chair) conducted the meeting. There was a request for patent declarations regarding the PC57.637 document and none given.

There was a motion to approve the March 9, 2010 Working Group minutes by Don Cherry and a second by TV Oommen. The approval of the minutes was unanimous. The discussion of the meeting included a review of some of the IEEE C57 guides that have cross references to C57.637. There was discussion about the C57.106 history in regards to inappropriate application of equilibrium curves. There was also and cold start warnings in C57.106 that may be provided in the PC57.637 revision. Another topic discussed was the unresolved status of the “re-refined” transformer oil within the ASTMD27 membership. The chair then noted that the PC57.637 scope states “This guide does not cover the used of oil in new apparatus under warranty.” The Power Point © presentation will be posted on the Insulating Fluids Subcommittee web site.

7.3.3.5. PC57.155 – Guide for Interpretation of Gases Generated in Natural Ester and Synthetic Ester Immersed Transformers Chair Paul Boman, Secretary John Luksich

The TF Report given at the Sub-Committee Meeting:

The WG met Tuesday morning, October 26. Patrick McShane substituted for John Luksich f or taking the minutes. A quorum was not achieved.

This was the first official meeting of the new WG. The WG PAR was approved right after the Spring NESCOM meeting. A presentation on the phenomenon of Natural Ester Fluids (mainly based on the soy bean based natural ester fluid) was presented by Dave Hanson. The presentation also discussed stability or stray gassing. It showed the need to protect the sample after it has been taken from sunlight. Further investigation will be needed on CO2 and H generation. There are two other labs presently working to verify the information prior to putting it into the Guide.

The WG chair thanked Dave Hanson for his excellent presentation. Mentioned UV exposure can create CG so samples should not be exposed. Further investigation is required for ethane, hydrogen, and CO gases. Two other labs are working on reviewing the issue. The Chair will be trimming the roster to help achieve quorum.

Minutes (unapproved) of the WG meeting as submitted:

Meeting was called to order at 9:30.

No Patent Disclosures were reported to Work Group

Attendance: 16 members out of 49 members were in attendance, total attendance was 40 and 5 people requested membership. A quorum was not present.

Duval and Sim reported on Soybean fluid filled transformer rated at 200 MVA. Investigation should be completed by the end of 2010.

Chairman stated that the Working Group roster will be review for member attendance. Inactive members will be removed from the Work Group.


7.3.3.6. TF Guide for Field Application of Natural Esters Chair Jim Graham, Vice-Chair Jerry Murphy

The TF Report Given at the Sub-Committee Meeting:

Jim Graham presented.

The TF has completed its assignment. A PAR was submitted but did not meet with approval from the Administrative SC. A new PAR will be submitted to create a new WG to revise C57.147 instead of creating a new Guide. Patrick McShane and Clair Claiborne volunteered to pick this up as Chair and Vice-Chair respectively and Jim Graham will take on duties as the Secretary.

Minutes (unapproved) of the WG meeting as submitted:

Fall 2010 Report

The task force for field applications of natural ester fluids has completed its assignment and did not meet. An application for a PAR to develop a new guide was prepared and submitted, but the PAR request was denied by the administrative subcommittee. Instead, there was support to incorporate the field applications material into C57.147, the natural esters fluids guide.

This task force will disband, and be replaced by a working group charged with revising C57.147 to include the field applications material.

Respectfully submitted,

James W. Graham Task Force Chair – Guide for Field Application of Natural Ester Fluids

7.3.3.7. TF on Particle Count Limits in Mineral Oil - Chair: Mark Scarborough

Mark Scarborough– Chair, T.V. Oommen- Vice-Chair , Paul Boman - Secretary

The Report given at the Sub-Committee Meeting:

Mark Scarborough presented.

This Task Force was established after the spring 2008 meeting to investigate the issue and determine if there is a need to develop a standard or guidelines for particulate limits for new fluid, as received in new equipment, and continued use.

There were presentations on the TF history and methods of testing and differences in measurements done today as compared to in the past.

The TF will continue to work on developing a scope statement so that as it progresses they can ensure that they are staying within the scope of their task.

A web based survey was sent out to the Transformer Committee in an attempt to collect information on what others are doing in industry and the test methods and limits they use. The survey will remain open until December 31st of this year.

TF meeting minutes (unapproved) as received:

Meeting Date: 10/25/2010 Time: 1:45 – 3:00 PM

Attendance: 17 members out of 29 members were in attendance, total attendance was 54 and 7 people requested membership.

The meeting was called to order at 1:45 PM. Attendance rosters where circulated.

The following agenda was followed:

1. Introductions & Roster 2. Patent Disclosure 3. Origins 4. Activities to Date 5. Member List / Quorum 6. Purpose / Scope 7. Mini-Tutorial 8. Survey / Survey Results 9. Back to Purpose / Scope 10. Next Steps / Discussion 11. Adjournment

The IEEE Patent Disclosure policy was reviewed. No patents were disclosed.

Attendee introductions were made by group.

Quorum was established as the TF membership role call was performed.

A motion was made and seconded to approve the Spring 2010 TF Meeting Minutes as written. The motion was passed unanimously.

A review of Task Force history was provided.

T.V. Oommen presented the background and history of particle counts and the available particle count references. The presentation will be made available on the IEEE website. T.V. made a proposal for limits based on his research.

Dave Hanson provided samples of ACFTD and MTD used to calibrate particle counting equipment. He also provided slides with 2.5mg of the each material. This represents 2,250 particles / ml between 2-5 µm.

Comments on presentation:

• Jin Sim Comment: Additional references given; F.M. Clark and R.T. Harold. Jin Sim will provide technical papers to Chairman. Also, Jin Sim asked that the TF consider a minimum particle count limit.

• Elgar Trummer Comment: D-1816 dielectric strength uses very small gaps, when gaps increase to a practical size found in transformers, >5 μm particles have a large affect on dielectric breakdowns. Practical gaps are 20, 50 and 100 μm wide.

• Yang Baltun in favor of clean transformers but not cleanliness limitation.

Chairman did a quick review of survey results from the Particle Count Survey #1 sent out October 18, 2010 via the IEEE Transformer Committee e-mail distribution system.. The results will not be posted on the IEEE Transformer Committee web site at this time. The TF needs to review and “normalize” the responses provided. As of October 25, 2010, 63 respondents have completed the survey.

Chairman presented a Purpose / Scope statement for the TF. No motion to approve it was provided. It was agreed to send the Purpose / Scope around for comment to the TF members for a vote.

Chairman reviewed next steps for Task Force.

At 3:00PM a meeting adjournment was motioned and seconded by group.

The presentation used for the meeting will be posted on the IEEE Transformers Committee web site.

7.3.3.8. TF on Moisture in Oil - Chair: Bob Rasor

The TF Report given at the Sub-Committee Meeting:

Sue McNelly presented for the TF.

The TF presented data to demonstrate the many trends that can be seen with moisture and how all data parameters may need to be considered. Data was presented from online monitors and Karl Fischer testing. The data presented and the comments following involved interest in how there were noticeable variations in the water content and saturation based on temperature.

The TF Meeting Minutes (unapproved) as Received:

TF on Moisture in Oil Monday, October 25th, 2010 3:15 pm Toronto, Ontario Canada

The meeting was called to order by Chair Bob Rasor at 3:20 pm. There were 118 attendees. 17 of the 31 members were present. And 14 requested membership.

Members attending were: Bob Rasor Hali Moleski Dave Hanson Oleg Roizman Claude Beauchemin Juan Castellanos Jim Thompson Paul Boman Dinesh Chhajer Valery Davydov Don Cherry Jin Sim Mark Scarborough Don Platts Tom Prevost Mark Tostrud Shuzhen Xu

Attendees requesting membership were: Tom Melle Brian Sparling Tim Raymond Stephanie Denzer Gary Hoffman Bob Ganser Jr. Rowland James Luiz Cheim Larry Weathington James McIver Barry Ward David Woodcock Poorvi Patel Terry Martin

Agenda 1. Roster was sent 2. No patents were disclosed 3. Introductions were given 4. Reviewed scope 5. Dates of recent 5 conference calls were given 6. Presentation was given that included

i. Brief description of nomenclature and equations ii. Summary of moisture in standards/guides

iii. Data examples from both online monitors and Karl Fischer results were presented by Oleg Roizman and Claude Beauchemin

In summary, the TF presented data to demonstrate the many trends that can be seen with moisture and how all data parameters may need to be considered. Data was presented from online monitors and Karl Fischer testing. It was noted that top oil relative saturation can be much different than bottom oil relative saturation. Data examples also demonstrated that moisture content (ppm) responds to temperature and that that season affects moisture data. Relative saturation was shown to stay relatively stable as compared to moisture content on these graphs. Data also supported that relative saturation could be high (greater than 20 percent) when compared to the water content (ppm) at low temperatures. When oil temperature increased, water content also increased dramatically, often shifting between acceptable and unacceptable levels within days.

7. Discussion and questions followed 8. Meeting was adjourned at 4:30pm

Comments provided at the end of the meeting regarding the presentation include the following:

• Paper affects the correlation between temperature and relative saturation

• Failures have been seen due to moisture. Field dry-outs reduced the ppm of the oil drastically, however, after many years the moisture came back. The critical question is what is wet and what is dry.

• The shifts in calculated ppm vs. relative saturation appear to be different in the presented graphs. This is possible due to the time period of data, a larger time period graph will look different.

• The importance of online monitors and relative saturation was stated

• Also, online monitors actually measure relative saturation and therefore do not introduce the error in calculation.

• Industry mainly uses Karl Fischer and many conversions are used to calculate relative saturation from ppm. If we keep using KF, the important question will be to define the key levels.

• Transformer specifics such as load and design must also be considered.

• Karl Fischer method measures total water content. However, only need to know how much water is free to move as some water binds with compounds.

7.3.4. Old Business:

None

7.3.5. New Business:

C57.146-2005 - Guide for Interpretation of Gasses Generated in Silicone-Immersed Transformers – This standard was set to expire at the end of the year. A request for reaffirmation was made. Jerry Murphy has agreed to head up this reaffirmation process.

Patrick McShane is reviewing TC Standards and Guides for the various nomenclatures used for transformer dielectric coolants with the intent to create uniformity, obvious omissions of various alternative fluids in existing C57 standard, and areas where revisions may be necessary in existing standards based on the suitability, or unsuitability, of alternative fluids based on typical property differences with the standard mineral oil.

Insulation Life Subcommittee - Unapproved Meeting Minutes October 27, 2010 – Toronto, Canada

8.4 Insulation Life Subcommittee – Bruce Forsyth, Chairman The Insulation Life Subcommittee met in Toronto, Canada on October 27, 2010 at 8:00 AM. The minutes of our meeting in Lombard, IL on October 28, 2009 were approved as written. The minutes of our meeting in Houston, TX on March 10, 2010 were approved with the following correction. The date on the meeting minutes will be changed from 2009 to 2010. A roll call of the members revealed that a quorum was present. The attendance roosters show that the meeting was attended by 184 people, 54 of 75 members and 130 guests. 26 guests requested membership. 8.4.1 Chair’s Report The Spring 2011 IEEE Transformers Committee Meeting will be held in San Diego, CA in March. The Fall 2011 meeting location has not been announced. All of the Working Groups and Task Force Chairs are encouraged to utilize the following Attendance/Membership process. The membership should be open for the first two meetings. After that time, membership should be at the discretion of the Chair. If a member does not attend for two consecutive meetings, they should be removed as a member. The IEEE patent disclosure policy was discussed. None of the members or guests present identified any patents associated with the work of the Subcommittee. 8.4.2 Project Status Reports 8.4.2.1 C57.91 Loading Guide C57.91 is currently in ballot. The PAR was modified so it matched the document being balloted. In addition to the modification, a PAR extension has been requested to allow for the resolution of any ballot comments. 8.4.2.2 C57.100 Thermal Evaluation Guide C57.100 has been balloted. Currently, comments are being resolved. A PAR extension has been requested to allow for the resolution of these comments.

8.4.2.3 1538 Guide for the Determination of Maximum Winding Temperature Rise in Liquid Filled Transformer

1538 expires at the end of 2010. We have three options for this standard. We can let the standard expire, we can re-affirm it or we can revise it. At this time, a re-affirmation ballot for 1538 has been initiated. A one year extension of the standard has been requested to allow for the re-affirmation ballot. During the last re-affirmation ballot several comments were received. Bill Chiu will help review these comments to determine if any are significant. If we have significant comments, a PAR to revise it will be submitted. In this case the standard will be valid for an additional four years. 8.4.3 Working Group and Task Force Reports 8.4.3.1 Working Group for the Revision to C57.91 Loading Guide – Don Duckett The working group was called to order by Chair Don Duckett at 9:35 am. Vice Chair Carlo Arpino and Secretary Susan McNelly were also present.

There were 26 of 55 members present (quorum was not achieved). New requests for membership will not be entertained due to the Guide having gone to ballot.

Agenda: 1. Roll Call/Introductions 2. Patent disclosure announcement 3. Previous meeting minutes approval 4. Status of the present Guide 5. Adjournment

A roll call of members present and introductions of members and guests were made.


Approval of minutes from the Spring 2009 meeting in Houston, Texas was not done due to a lack of quorum.

Status of the present Loading Guide:

The Guide was set to expire and be withdrawn at the end of this year. A PAR extension was requested before the October deadline for the December NESCOM meeting.

Updates to the guide were made and the document is presently out for ballot. The ballot will close October 30th. Minimal modification were done to insert the voltage regulation section,

3

items such as gas bubble generation, and incorporation of the corrigenda and errata documents. In addition, the Guide was brought up to present IEEE requirements regarding style, metrification, equation presentation, etc.

Don indicated that the next step will be to form a ballot resolution group to review the comments that are received during the ballot process. A request for a ballot resolution group was made at the Spring 2010 meeting and the following had volunteered: Dave Wallach, Juan Castellanos, Don Platts, Tom Prevost, and Roger Verdolin. Tim Raymond volunteered to also help with the ballot resolution.

One of the comments was that even though the guide supposedly indicated that voltage regulators was added, there was no actual content added regarding voltage regulators. Tim Raymond commented that there was an old document that covered voltage regulators that has been retired. This was the reason behind adding voltage regulators into the C57.91 Guide. Robert Tillman indicated that he had written some sections covering voltage regulators a couple years ago and will reprovide that information to Don Duckett for possible addition for the recirculation ballot that will need to be submitted.

Transformers (C57.100) – Roger Wicks 8.4.3.2.1 Introduction and Rosters and Quorum Call The working group met on Monday, October 25, 2010 at 11:00 AM with 16 members and 41 guests attending, with 5 guests requesting membership. As we are currently in the IEEE Balloting process for this document (ballot resolution stage), we are not adding any new members at this time. As there were only 16 members of the 34 on our roster, we could not conduct official business during this meeting. 8.4.3.2.2 Approval of minutes from March 8, 2010 meeting

4

The minutes of the March 8, 2010 meeting in Houston, Texas had no issues, but could not be formally approved due to the lack of a quorum. They will be circulated to the working group electronically for approval. 8.4.3.2.3 Patent Disclosure The chairman asked if anyone knew of any patents that could pertain to this project. There were none. 8.4.3.2.4 Discussion As a result of discussion of our working group minutes at the Insulation Life Subcommittee meeting, a straw ballot of the working group was conducted prior to balloting our document in the my-ballot system. During the working group survey ballot as well, questions were asked of the working group key questions for which the chair anticipated negative ballots. As a result of the working group survey ballot and the questionnaire, a Draft 3 was developed and used for the official IEEE ballot. This Draft 3 document provided a successful ballot, and negative comments are in the process of being resolved, using the ballot resolution group identified at our last working group meeting. Once the ballot resolution group has completed their work, the document will be recirculated to allow completion of the revision work. A PAR Extension has been requested as we have missed the opportunity to have a completed document submitted to the IEEE Standards board by mid-October. 8.4.3.2.5 The meeting adjourned at 11:15 AM. 8.4.3.3 Task Force on High Temperature Liquid-Immersed Transformers (PC54.154) –

Richard Marek The fifth meeting took place on Monday, October 25, 2010 in the Jackson/Carmichael Meeting Room at 1:45 pm, at the Hilton Downtown Toronto Hotel, Toronto, Ontario, Canada. Introductions were made and attendance sheets were circulated. The IEEE patent policy was discussed and there were no concerns regarding patents. At 36 members, a quorum was established with 22 members and 56 guests present. The minutes from the Houston meeting were approved as submitted. A series of comments to draft 4 were continued from the previous meeting and the first comment concerned Fig.3. The chair noted that he had discovered an error in the curves where the labels for the axes were reversed. The floor was then given to Ziomek and Krishnamurthy who presented an alternative set of curves to illustrate the temperature distribution for different materials used in three of the insulation systems. The chair stated that the new curves would not match the text, but a search could not determine the reference. A task force was then formed to determine the need for the original curves and also to

5

determine if the three new curves were needed for clarification. The members of the task force are: Ziomek, Szewczyk, Vijayan, Lopez-Fernandez, Sauzay and Jaroszewski. The next comment was submitted by Nordman and concerned Table 1 and the average winding temperature rise for the hybrid insulation system which is shown as a range of 70-95°C with 5°C increments in draft 4. However, he stated that draft 5 satisfied his concerns by showing only the maximum temperature. Nordman then requested an additonal column to this table to establish a higher temperature limit for celulose when used in ester liquid. The chair declined this addition, expressing his opinion that establishing the temperature limits of a specific material or combination of materials in liquids was beyond the scope of this working group. He also stated that while he could imagine that insulation in different liquids could improve the thermal capability, there is no accepted test procedure available to define such capability. This is in contrast to the many different thermal classes available for dry-type insulations. The chair suggested the Transformers Committee should be surveyed to determine the concensus opinion and asked Bruce Forsyth, chair of the Insulation Life SC if this working group could do this. He thought the group could not, but they could request the SC to make a proposal to the Committee. However, Asano protested that most would just vote “no” since they had no interest and were not participating in this working group. It was proposed that many in the industry were looking to the standards to provide guidance. And who should define these limits? This was countered by the statement that this made it even more important to make sure the standards were developed on a strong technical base. The chair then stated that acceptability was often determined by customer acceptance and then eventually this acceptance becomes a part of the standard. But how long should this process take? The chair then challenged the proponents to develop an annex that presents a convincing technical argument to support the higher temperature limits proposed. This annex would be included in the document even if a Committee survey did not support the proposal. The members of the task force are: Asano, Corkran and Cherry. The next comment concerned a request by Jaroszewski to require a temperature rise test as a routine test for units that are rated as only OD or OF to prevent catastrophic damage to the transformer. Krishnamurthy commented that collection of DGA data should also be required, not just desirable. He proposed a minimum duration of the temperature rise test such as 12 hours to make sure enough time elapsed to capture gas from abnormal heating. However, a show of hands did not support this motion. The meeting adjourned at 3:05 pm.

8.4.3.4 Working Group for Temperature Rise Test Procedures Section 11 of C57.12.90 - Paulette Powell

The Working Group met at 11:00 AM October 26, 2010 in Toronto III room of the Hilton Downtown Toronto Canada. A roll call of members was done. In attendance there were 14 members and 62 guests, 5 members requested in advanced and were granted to be excused for their absence. Total membership stands at 31, therefore and considering excused members we had a quorum. Four guests requested membership. All the participants introduced themselves. There were no patents disclosures. The minutes from the previous meeting March 9, 2010 from Houston Texas were distributed prior the meeting, posted on the SC website and also displayed at the meeting. The minutes were approved as written. Projects The discussion was centered on revision of a proposal made by the TF –Sub-clause 11.2.2e addressing scenarios wherein hot-resistance time data not being suited to fit an exponential decay curve. Marcel Fortin proposal for distribution transformers modified the sub-clauses as follows:

• Add to 11.2.2.c - At least one resistance measurement shall be taken on all terminal pairs within a time less than half the coils shortest time constant after shutdown.

• Add to 11.2.2d: Alternate 1 - A series of at least 10 resistance measurements shall be made on one terminal pair corresponding to a phase of a winding in less than 10% of the bulk oil time constant. Alternate 2 - At least 10 resistance measurements shall be made on one terminal pair corresponding to a phase of a winding. All resistance data points shall be recorded at no longer than 30 second intervals and no less than 10 second intervals.

• 11.2.2f: Modify to agree with timeframe specified in 11.2.2c. The first point was compared to what it is now in the last WG approved document, that calls for the first resistance data point to be taken as quick as possible and no later than 4 minutes after shutdown. There was concern over the lack of definition to distinguish distribution from power transformers or whether the same rules would apply to both types. There was a clarification made that the difference between power and distribution transformers is not by KVA or voltage, but by application as described per C57.12.80. Also, there were comments that the proposal would need of a standard calculation method for thermal time constants of distribution transformers. The group concurred there is not an easy single method of calculation.

7

A motion was passed to consult the distribution subcommittee on acceptance of the proposal, and get comments from them. Another motion was passed and voted on by the working group in order to accept the proposal as presented. The WG passed the motion by 5 positive to 1 negative votes. The proposal will be sent to the Insulation Life SC for circulation among members. Unfinished Business There was no unfinished business discussed New Business There was no new business discussed Due to lack of time for another activity, the meeting adjourned at 12:03 PM. Respectfully Submitted, Juan Castellanos, Vice-chair Marnie Roussell, Acting Secretary 8.4.3.5 Task Force on Furan Testing – Shuzhen Xu

Attendance: 22 members, total attendance was 52 and 3 requested membership (1) Reviewed the status of the position paper. 6 webinars since last meeting with task force subset group. The draft paper is completed with the contribution from 4 major participants: Shuzhen XU, Luiz Chin, Tom Prevot, Don Platt. (2) Discussed how we want to publish the paper Difference options to publish the paper were discussed: including publish it in serial papers in IEEE transaction, or insulation magazine. (3) Discussed future plan for the task force Based on the discussion, the task force decided the following two actions:

• Recommend to gather data for meaningful statistic analysis • The task force will wait the user’s comments and feedback on the paper to decide

whether there is need to develop a guide. (4) Discussions and questions session Various issues on how to use the furan analysis were raised by the participants: for example: what is the effect of oil processing on furan level, what is limit of furan? All the issues are covered in the position paper. So the answer from the task force is highly recommending participants read the paper and providing your comments to the task force. The task force group plans to review the received comments around in the end of Nov.

Recommendation No. 1

Revised wording to paragraph 5.11.1.3 of C57.12.00 Current wording: 5.11.1.3 Rises of metallic parts other than windings Metallic parts in contact with current-carrying conductor insulation shall not attain a temperature rise in excess of the winding hottest-spot temperature rise. Metallic parts other than those described above shall not attain excessive temperature rises at maximum rated load. Proposed revised wording: 5.11.1.3 Rises ….. Metallic parts other than those described above shall not attain excessive temperature rises at maximum rated load. Excessive temperature rise shall be interpreted to mean a temperature rise that results in an operating temperature that would exceed the temperature limits of the insulation material that is in contact with the metallic part.

9.11.4.2 PCS WG on “Test Code C57.12.90” – Mark Perkins, Chairman; Kirk Robbins,Secretary

1. Introduction of members and guests2. Patents3. Approval of minutes of the Houston Meeting (not official, as only 29% of the WG

membership was in attendance.) Motion and second, minutes approved unanimously, but since we did not have a

quorum the approval will need to take place at a future WG meeting.4. Old Business

New C57.12.90-2010 was published on October 15, 2010, including the newresistance measurement section and updates on zero sequence test.

Revision of Section 6 & 7. Polarity and Phase Relation Tests and Ratio tests – Weneed to discuss the latest proposal before sending for survey again. It was sent forsurvey in April 2009, with some (limited) comments received. Most replies seemedfavorable. From the limited replies there is concern that the document may nothave been reviewed in depth by the membership.o Ratio and polarity test observations:

Ratio and Polarity test is a single phase test done on either single ormultiphase transformers

Historically, separate tests for ratio and polarity were needed due to testequipment limitations

Today, equipment is available to test both simultaneously Some users still due separate ratio and polarity tests The term “Ratio Test” now often means both ratio and polarity Ratio test is actually a voltage ratio test, not a turns ratio test Effective ratio “Effective” Turns ratio “Nameplate” Voltage ratio

The ratio test allows field test results to be compared to factory baselineo A significant discussion took place on the information (actual turns or required

voltage) that’s provided on the nameplate. Mark requested that the WorkingGroup responsible for C57.12.00 provide some guidance on this question ofterminology.

o Mark noted the following purposed of Ratio and Polarity tests: Make sure transformer voltage ratio matches nameplate voltage ratio



Verify that the transformer is connected properly according to thenameplate vector drawing

Used to check for shorted turns or open turns Often first test done after a transformer incident to check for a failure Verify the tap changer position after changing taps

o The types of transformers tested include: Transformers with all winding terminals brought out to bushings that can

be tested directly on the terminals Transformers with some terminals not brought ought that must be tested

from the other terminals while shorting out one or more legs of the core Transformers with interconnected windings that can be tested with the

available terminals by some special procedure. Transformers with buried or interconnected windings that can only be

tested during the assembly process when internal connections areaccessible

o WG agreed to look at Ratio and Polarity sections at Fall 2007 mtg. inMinneapolis 9 pages of C57.12.90 for sections 6 and 7 Hadn’t been reviewed/revised for decades Modern methods were missing

o WG discussed and prepared a draft of suggested changes in 2008/2009o Surveyed first draft of Changes one year agoo 20 people returned surveyo 5 people submitted commentso The comments have been includedo As we move ahead, questions include:

What should we do now? Is there something missing? Should Sections 6 and 7 be combined?

A suggestion was made to including them before section 5 (a sequencereorder, not necessarily a combination) Do we need to expand purposes and background information? Do we need to reduce the sections? Should we just keep going with the proposed changes?

Steve Antosz suggested that we not go looking for new work, but simplysend the suggested changes (voltage ratio vs. turns ratio) to the group sothat we can get a feel for how everyone views these. C57.12.80 refers towhat we’ve been calling “Voltage Ratio” as the “True Ratio.”

The most recent revision removed Figures 2 & 3 – showing subtractive and additivepolarity. A comment was received that they had value from a learning/academicperspective. No one suggested brining those figures back into the standard.

It was suggested that we remove the first clause in 6.2.2 and in 6.3.2.1 that refersto a “ratio of 30 to 1 or less.”

Wye-zigzag connection was added to Figure 5. Mark noted that these figures arenot all inclusive, but representative of various configurations.

A comment was received that we remove section 6.3.3. No dissention was notedduring the meeting

Changes will be made in section 7 in line with better defining effective turns. A review of possible new wording was conducted for Transformers with

Inaccessible Neutrals (or inaccessible terminals).



A suggestion was made that Figures 2 & 3 be brought back in to aid users. It wasnoted that those figures were redundant with information already contained in thestandard. This question will also include this question – retain, move to annex, ordrop altogether.

The question of testing buried tertiary windings was reviewed. The group agreedthat this question should be included on the survey to be sent to the working group.

5. New Business A proposal was made to provide a section on ratio measurement using a

capacitance bridge. However, no details were offered at the meeting. This processmay be considered if details are received in the future.

6. Motion for and unanimous agreement for adjournment of this unofficial meeting tookplace at 9:45am.

9.11.4.3 PCS WG on “Guide for the Application and Interpretation of Frequency ResponseAnalysis for Oil Immersed Transformers”, PC57.149 –– Chairman; Charles Sweetser

There were 63 people in attendance, and a quorum was established. The first order ofbusiness was to show the slides regarding patents, assurances and inappropriatebehavior. The minutes from the Houston, TX 2010 meeting were not approved. This willbe addressed at the next meeting.

Working Group Chair UpdateDraft 8 was circulated within the subcommittee on August 10, 2010. Comments werecollected and are ready for discussion, and are summarized as follows:

1. It was recommended that DETC be spelled out in the instance of first time use; De-Energized Tap Changer.

2. In Clause 3.2 FRA baseline measurement, lines 26 & 27, it was recommend adding afew clarifying words to the second and third items in the list: Insert "Prior to" in front of"Short-circuit testing"; Insert "Required by" in front of "Customer Specification"

3. In Clause 4.5 Test Leads, line 23. The reference to 'Clause 4.5' for self-checking leadintegrity needs to be removed, since this reference is already in Clause 4.5.

4. Clause 4.7 LTC and DETC positions, line 10. The phrase "the previous tap position"should be restated more clearly. 'Previous' depends on the direction the tap changerhas moved, and is not clear. Matt Kennedy will provide new text for clarification.

5. Clause 4 did not include information regarding 'shipping configuration'. The informationalready exists in the transportation guide and will be provided by Matt Kennedy andGreg Anderson.

6. The Clause 1.2 "Purpose" states that FRA is ideally a comparative type test andreferences the term "previous measurement." However, FRA has value where nocomparison is available.

The new Purpose reads as follows and will be submitted for change during the ballotrequest process:

The FRA measurement is a comparative type test, where a transfer functionmeasurement from one winding circuit arrangement is compared to a previousmeasurement, a similar transformer, or between phases of the same windingarrangement. This trial use guide will aid the user in the process to produce uniformand repeatable results that can be successfully used and archived for analysispurposes for decades into the future.



7. The use of "Short Circuit Test" will be changed to Short Circuit Measurement in thedocument.

8. In Clause 3.4, there is nothing about the frequency interval at which the FRA tests aremade, and a sufficiently small interval should be made in order to capture all series andparallel resonances. A statement will be added that requires a minimum sample rate of200 measurements per decade either spaced linearly or logarithmically.

9. In all tables in Section 4, with respect to the Transfer Admittance (TA) measurements,there needs to be a better description of which terminals are grounded. A footnote willbe added to better clarify which terminals should be grounded.

10. In Table 5 and Table 6 in Section 4, there is reference to "Tertiary". Since these tablesrefer to three-winding transformers, Tertiary will be replaced by Low Voltage (Y).

A vote, under quorum conditions, was performed approving the ballot process. The ballotprocess will be initiated once the changes are made.

9.11.4.4 PCS WG on “General Requirements C57.12.00” – Steve Snyder, Chairman; EnriqueBetancourt, Secretary

The Working Group met at 3:15 PM on Monday, October 25, 2010 with 31 members and63 guests present. After review and clean up of the Working Group roster, the currentWorking Group membership stands at 57 members ; therefore we did have a quorum atthe meeting. The following six (6) guests requested membership, that will become effectiveonly after confirmation of attendance to two (2) consecutive meetings:

Peter Balma Peter M. Balma Engr. ConsultingWillie Mangum Niagara Transformer Corp.Richard von Gemmingen DOMINIONSanjib Som Virginia Transformer Corp.Jose Izquierdo Siemens Guanajuato, MexicoJavier Arteaga ABB South Boston

Three (3) new members will become active for the next meeting:Jose Gamboa SiemensKrishnamurthy Vijayan CG Power System CanadaSteve Schroeder ABB

Following introductions, the minutes of the March 8, 2010 Houston were approved.Working Group members were then asked if anyone was aware of any applicable patentactivity that might impact our work. No patent issues were disclosed by anyone.

The chairman provided an update on the status of C57.12.00. After several recirculations,the document was finally approved and officially published on Sept 10, 2010.

The meeting began with Old Business, WG item 82 :

WG Item 82, Clause 7.1.4.4 Stabilizing WindingsAddresses an issue raised in an earlier ballot of standard C57.12.00 which requested :

(a) Recommendations for guidelines to determine MVA rating of buried tertiary windings,(b) To define the conditions under which this MVA is applicable, and(c) Determine the tests or calculations necessary to prove the tertiary MVA rating.



The meeting of the Task Force on Stabilizing Windings took place on Monday October 25,with 19 of 30 members present. Chairman Enrique Betancourt presented a summary of theprogress accomplished by the group. The text proposed for a new clause withinC57.12.00, that would address the thermal rating of stabilizing windings, was circulatedamong the members of the Performance Characteristics and Insulation LifeSubcommittees. The comments from 23 respondents were reviewed and extensivelydiscussed. Main items still under discussion include a validation of a proposed 20% as aminimum-sufficient rating for stabilizing windings of autotransformers, and the appropriatetemperature limits for transient loading of stabilizing windings.

Active participation of Mr. V. Sankar helped to reinforce the need for a thermal rating forstabilizing windings, independent of their short circuit strength. An additional contributionfrom Mr. K.Viyajian helped clarify the meaning of the minimum rating proposed by defaultfor stabilizing windings, in the case where the users’ specs leave this item open.

The task force chairman will prepare a new version of the proposed text for inclusion inC57.12.00 that first will be reviewed among the task force membership, and then sent foranother survey within the PC SC and IL SC.

The Task Force received a report on the status of their application to begin working on thedevelopment of a “Guide for The Application of Tertiary and Stabilizing Windings”. A Title,Scope and Purpose for the document have to be agreed within the members of the groupbefore the task force can begin this work – hopefully before the next meeting in San Diego.

Before closing the meeting, Xose-Lopez from the University of Vigo (Spain) gave a shortpresentation on his paper related to hot spot calculations for Y-Y transformers w/ostabilizing windings.

WG Item 87, Table 18 Short-circuit apparent power of the systemThis item is based on a comment (negative ballot from 2006) that the system short circuitcurrent levels listed in Table 18 are unrealistically high, leading to designs that may beuneconomical. The suggestion was to limit these assumed fault current levels to 63 kAand lower.

Pierre Riffon explained the background of his comment, and the chairman opened the floorfor discussion. Loren Waagenar explained that the table was derived in the 70’s, projectinghigh future system fault levels. The chairman explained that other committees within IEEEwere addressed with the question, with very few responses. IEC standards were reviewedand lower values found for system fault currents. After considerable discussion, a motionwas made and seconded, to form a new task force with the objective to review this issue.Bruce Forsyth volunteered to lead the new task force.

Under New Business, the discussion began with WG item 91 :

WG Item 91, Discussion on Core Loss Measurement Before/After Impulse TestThis Item was a referral from PCS Chairman Stephen Antosz.

Requested Change : Discuss the merits of specifying the sequence in which the core lossmeasurement is performed relative to the impulse test. Presently the standards do notspecify, but it has been suggested that the impulse test may influence the core lossmeasurement.



It was explained that some users currently specify test sequences that deviate from thesequence in C57.12.90, and that in some cases it is specified that the core lossguarantees be met by testing immediately after dielectric tests. After a series of commentson historical data and references to other standard bodies, a motion for “do nothing, basedon no technical sense perceived” was approved by 27 in favor vs. 3 opposed. Item 91 isconsidered closed.

WG Item 92, Add to Nameplate, Oil Volumes from 25C and 65C to Low Alarm

Change Requested by : Malcolm Thaden – C57.12.00 - 2009 Ballot Comment

Requested Change : There is an interest in knowing how much oil would be spilled beforethe liquid level gauge would reach the low level and alarm. Add liquid level volumes from25°C and 65°C levels to low oil liquid gauge level.

After initial discussions, the Working Group felt that a better understanding of Mr. Thaden’sconcern was necessary before trying to resolve his comment. As Mr. Thaden was notpresent at the meeting, the chairman of the WG will get in contact with him to gather moreinformation about his comment, before the next meeting.

The chairman then asked if there was any new business, with none received from theattendees.

9.2.4.4.1 Task Force on Tertiary/Stabilizing Windings Enrique Betancourt

The Working Group met at 8:00 AM on Monday, October 25, 2010 with 19 members and83 guests present. The current Working Group membership stands at 30 members;therefore we did have a quorum at the meeting. Six (6) guests requested membership that,by current rules, will become effective after attendance to two (2) consecutive meetings:

Ajit Varghese Waukesha ElectricBogdan Ionescu Pennsylvania TransformerDoug McCullough Maxima / HyundaiJavier Arteaga ABB South BostonMarshal Stewart EFACECRobert F.Tillman Southern Co. Services

According to IEEE TC attendance rules for membership, after this meeting two (2) newmembers become now active for the next meeting:

Bogdan Ionescu Pennsylvania TransformerJennifer Yu Pacific Gas & Electric

Following introductions, the minutes of the March 9, 2010 Houston meeting wereapproved. Working Group members were then asked if anyone was aware of anyapplicable patent activity that might impact our work; no patent issues were disclosed byanyone.



Old BusinessOur work addresses an issue raised in an earlier ballot of C57.12.00 that requested:

(a) Recommendations for guidelines to determine MVA rating of buried tertiary windings(“Stabilizing Windings”, as defined in C57.12.80)

(b) To define the conditions under which this MVA is applicable, and(c) Determine tests or calculations necessary to prove the (buried) tertiary MVA rating.

The chairman presented a summary of the progress accomplished by the group inprevious discussions. It was agreed that the short circuit capability of Stabilizing Windingsis properly addressed within C57.12.00 (Clause 7.1.4.4.), and that a new paragraph wasrequired to accomplish our TF objective.

The text proposed by this Group for a new Clause 5.11.1.2 within C57.12.00, to addressthe thermal rating of stabilizing windings, was circulated among the members of PC SCand IL SC in August of this year.

Text submitted for comments:

5.11.1.2 Stabilizing WindingsStabilizing windings shall be designed to withstand the thermal duty of the circulatingcurrent resulting from temporary load and or voltage unbalance on the main windings, asspecified by the user. The main windings' unbalanced load currents and or supply voltagesshould be specified in magnitude, angle, and duration, by the user, to allow verification ofcompliance with maximum allowable temperatures according to Section 5 of the presentstandard.

In the event no continuous thermal duty for the stabilizing winding can be established fromthe user’s specification, the manufacturer shall design the stabilizing winding consideringthe circulating current resulting from a full single phase load in the largest main secondarywinding (for more than one secondary winding), and infinite bus supply on the primarywinding. This is taken to be 33.3% of the transformer rating. For autotransformers, seeNote 1 below.

The manufacturer shall verify transient and continuous loading calculations for stabilizingwindings temperatures in order to demonstrate adequacy to the requirements establishedin the foregoing clauses. Initial conditions for those calculations will be considered as thetransformer or autotransformer operating at its maximum continuous rating, beforeswitching to the single phase loading conditions specified. The manufacturer is to providethe user calculated values of hotspot and average temperatures for the stabilizing windingto demonstrate that they comply with maximum allowable temperatures.

Note 1: For the particular case of Autotransformers, manufacturers have been usingdifferent criteria for dimensioning of the stabilizing windings: for example, “33% (1/3) of thehighest calculated base kVA of the series or common winding (base currents forautotransformers defined by Clause 7.3.3)”, or as another example, “33% of thetransformation capacity of the autotransformer”. Here the approach is different: themagnitud of the circulating current has to be determined from the autotransformer’simpedance network, as proposed by the manufacturer.

End of submitted text –



The comments from 23 respondents were reviewed and discussed during the session.There were eleven (11) “Approval”, eleven (11) “Approval with comments”, and one (1)“Not Approved” responses. Main concerns were overdimensioning of SWs, and SWspecific reduced capacity requirements for Autotransformers.

Active participation of Mr.V. Sankar contributed to resolve the recurrent question of theneed for a thermal rating for Stabilizing Windings, independent of their short circuitstrength. New material provided by Mr. K.Vijayan was introduced, describing approximaterating for SWs, as calculated by the methodology proposed in the new clause. Accordingto Mr. Vijaian’s calculations, 20% of the equivalent transformer rating seems adequate fora wide range of sizes of Autotransformers and Transformers. The material is yet to befurther deployed and distributed for discussion among the TF Members.

The chairman will prepare a new version of the proposed text for inclusion in C57.12.00, tobe reviewed among the TF membership, and, after that, a recirculation of the text will becarried out within the PC SC and IL SC.

The comments received form the survey that were identified to fall within the scope of afuture Application Guide for Tertiary and Stabilizing Windings were segregated for futurework of the Group.

The TF got report on the status of its application for working on the development of a NewGuide for Application of Tertiary and Stabilizing Windings. A Title, Scope and Purpose forthe document have to be agreed within the members of the group before the next meetingin San Diego.

Main items still under discussion are: validation of a proposed 20% as a minimum-sufficientrating for SWs of autotransformers, and the temperature limits for transient loading ofSWs.

The next item in the Agenda was a short presentation from Xose-Lopez from the Universityof Vigo (Spain) on his paper related to hot spot calculations for Y-Y transformers w/ostabilizing windings.

New BusinessThe chairman asked for any New Business, with no input from the attendees.


9.11.4.5 WG on “IEEE Standard Requirements, Terminology, and Test Procedures for NeutralGrounding Devices”, PC57.32 – Steve Schappell, Chairman; Peter Balma, Vice-Chair

The Neutral Grounding Devices working group was called to order at 9:32 AM on October26, 2010. There were 19 attendees: 9 members and 7 guests, with 3 requestingmembership. Copies of the previous minutes and Draft 9 of the standard were distributed.

1. IEEE patent policy was reviewed and the group was asked if there were anydisclosures. There were none.

2. It was determined that a quorum of was present.



3. The minutes from the Houston, Texas meeting on March 9, 2010 were approved.

4. The PAR for the working group is valid until the end of 2011. The input received fromworking group members was reviewed and acknowledged, and copyright permission toutilize IEC standard material on ground fault neutralizers.

5. The working group then proceeded to discuss Draft 9 of the document. Clauses 4 and 5 combined into service conditions, it was suggested to rename

Clause 4.2.1 to “External insulation.” There was a discussion of Tables 9 and 10 and of their origin and use. Grounding

transformer suppliers indicated they still used the Tables. Sheldon Kennedyindicated he had been researching the values, and believes they come from severalpapers written in the 1950’s. It was also suggested that Westinghouse T&D bookmight contain some additional information.

An extensive discussion of a 4 second rated device as outlined in Table 4 andseveral other clauses then followed. The discussion considered user requests,typical applications, and industry experience as far as the types of devicesrequested. A motion was made and seconded to remove the 4 second rating fromthe Table 4, after discussion, a vote was taken and the motion was rejected.

The discussion continued on rated times and considered adding a separate columnto Table 4 to cover resistors. Moreover, the impacts of Table 4 on transformer andreactor design were also discussed. In addition, there were some discussion ofsystem design and breaker and relaying considerations. There was a motion and asecond to maintain the 4 second value in Table 4 and to add a new row in theTable for less than 4 second ratings. A vote was taken and the motion rejected. Inadditional discussion, Mike Sharp offered for the group’s consideration a table oftypical grounding reactors. The table illustrated the various time requirements thathad been requested by users. After further discussion, another motion and secondwas made to revise Table 4 to indicate a rated time of 10 seconds or less and wasapprove by vote on same.

A discussion of Table 1, insulating material, determined it needs to be reviewedrelative to all neutral grounding devices, and perhaps should consider oil-filleddevices.

Clause 13.3 Temperature coefficient of resistance was reviewed with the help of anexample. The example demonstrated the impact of the change of resistance andcurrent as a result of the large temperature change in neutral grounding resistorsduring normal operation. The group needs to continue its work in this area anddetermine how to best present this material in this standard.

It was indicated that the group had agreed on a 40°C maximum ambienttemperature, but that the document still needed to be updated to reflect this.

Other general updates and revisions to Draft 9 were also reviewed.

6. A suggestion was made to look at the title of document and consider its impact orclarity relative to grounding transformers, or as alternative to provide additionalbackground to neutral grounding devices in the beginning of the document.

7. The meeting adjourned at 10:52 am.



9.11.4.6 TF on “Semi–Conductor Rectifier Transformers”, C57.18.10 – Sheldon Kennedy,Chairman

The Working Group met on Tuesday, October 26, 2010 at 3:15 PM with 7 members and 7guests present. Sheldon Kennedy chaired the meeting. We did not have a quorum.

The IEEE disclosure statement was discussed. There were no patents pertaining to thisstandards work for which any members had awareness.

The minutes of the March 9, 2010 meeting in Lombard, Illinois were read but could not beapproved due to the lack of a quorum.

This Task Force is to work on a few special items while we still have the group together.

The chair made a proposal for a clause on electrostatic ground shields. After muchdiscussion, Dhiru Patel and Subhas Sarkar had volunteered to offer some revisions to thisproposal at the last meeting in Houston and submit them before the Toronto meeting. Thiswas not received. Dhiru Patel offered that he would have his comments in a week or two.Don Ayers offered some comments that will be included, as well.

Phase shifted secondary windings with multi-pulse secondary windings such as 18 pulse,24 pulse, 36 pulse, 48 pulse and 54 pulse are becoming a great part of the motor drivetransformer applications, as well as higher current rectifier transformers. There is nodiscussion about these in the present C57.18.10 and this will need some work. We beganto discuss how we would incorporate these circuits into C57.18.10 since this is all relativelynew work since the document was originally published in 1998. Numerating additionalrectifier and transformer circuits was discussed. At our meeting in Lombard, Dhiru Patelinformed us that there were patents on a lot of the methods of phase shifting windings bythe drive and rectifier companies. Not wishing to have a problem with patents, the TaskForce decided to just propose general discussions of phase shifting windings and not giveany of the exact phase shifts that are being used in industry. This seemed the best way toaccomplish this. The Chair submitted a proposal of a general discussion of the topic for theTask Force to consider. It was well received but needs some additional comments bymembers. Members will give comments to the chair and a more complete proposal will besubmitted by the next meeting.

There was a discussion about determining the losses in specific regions due to harmonics.IEC has tackled this subject already in an Annex and this should be done in our nextrevision, as well. An example of the response of the windings to the 5

th, 7

th, 11

th, and 13

th

harmonic, for instance, is much different than the fundamental current when we examinethe leakage fields and loss densities with finite element methods.

There was a discussion about the standards being written in the Vehicular TransportationSociety of IEEE. A traction rectifier transformer standard, rectifier standard and many C37switchgear standards are being revised by this organization with emphasis on the needs ofthe transit and rail industry. Concerns about duplication of standards and conflicts in thestandards were raised. This standard has been withdrawn and nobody is aware of itsfuture direction.

The chair announced that the IEC Converter Transformers for Industrial Applications IEC61378-1 standard is under revision again. The chair discussed some of the highlights oftheir latest draft. We will ask IEEE to request a copy of their work for harmonization with



our document. To date, I have not been able to get approval to share the information. Afterthe meeting the chair again discussed this with IEEE and may be able to get this beforethe next meeting.

There were no further comments. Since we didn’t have a quorum, we couldn’t make amotion to adjourn, so we all just faded away at 4:00 PM.

7.6 POWER TRANSFORMERS – TOM LUNDQUIST, CHAIRMAN

The Power Transformers Subcommittee met on Wednesday, Wednesday, October 27th

2010 at 1:30 p.m. A quorum was present with 65 members and 120 guests.

The minutes from the spring 2010 meeting in Houston, Texas were approved with nochanges.

The chairman asked if anyone was aware of any patent conflicts, none were voiced.

7.6.1 WORKING GROUP AND TASK FORCE REPORTS

7.6.1.1 TASK FORCE FOR REVISION OF C57.17, REQUIREMENTS FOR ARCFURNACE TRANSFORMERS – Domenico Corsi, Chairman

Bob Ganser will take over as the Chair for this WG. Editorial changes recommended byIEEE will be made to the document and the Standard will be issued for balloting in thenear future. This work needs to be completed by October 2011.

7.6.1.2 WORKING GROUP FOR DEVELOPMENT OF PC57.143, GUIDE FORAPPLICATION OF MONITORING TO LIQUID IMMERSED TRANSFORMERSAND COMPONENTS – Donald Chu and Andre Lux, Co-Chairmen

The document has been balloted and comment resolution is in process.

7.6.1.3 WORKING GROUP FOR DEVELOPMENT OF PC57.148, STANDARD FORCONTROL CABINETS FOR TRANSFORMERS – Joe Watson, Chairman

The WG did not meet. The document is under revision in response to commentsreceived during balloting. The revised draft should be re-balloted in early 2011.

7.6.1.4 WORKING GROUP FOR DEVELOPMENT OF PC57.131, STANDARDREQUIREMENTS FOR TAP CHANGERS - William Henning, Chairman

The Working Group on Tap Changer Performance met on Monday, October 25, 2010 at1:45 pm with 9 members and 28 guests present. At the beginning of the meeting, justafter introductions and a call for patents, a quorum check indicated no quorum.However, by the end of the meeting we did have a quorum with nine members.

The working group is in the middle of the comment resolution process on its ballot ofDraft 1.5 of C57.131, Requirements for Tap Changers. The comment resolutioncommittee reviewed the comments, via email, before the meeting. Of 130 comments,seven were identified as needing further discussion. Most of the meeting time wasdevoted to discussion of the seven topics.

9.12Power Transformers Subcommittee

Also discussed was the need to regenerate artwork for the Appendix. These figuresconsist mostly of phasor diagrams, circuit diagrams, and other simple line drawings. Inthe draft used for balloting purposes, the diagrams were cut from the PDF file of thecurrent version of C57.131 and pasted directly into the Word document. This processwas considered expedient for balloting but not adequate for final publishing. The figureswill be redone prior to REVCOM submission.

1. The comment resolution committee will review and finalize the working groupresponses.

2. Along with this, we will revise the document as response to some of thecomments.

3. We will upload the responses and conduct a recirculation.

The meeting was adjourned at 2:50 pm.

7.6.1.5 WORKING GROUP FOR DEVELOPMENT OF PC57.150, GUIDE FOR THETRANSPORTATION OF TRANSFORMERS AND REACTORS RATED 10,000KVA OR LARGER –Greg Anderson, Chairman

The WG did not meet. The document is nearly complete and a straw ballot of the WGwill be held before the end of this year. A one-year extension to the PAR will also berequested.

7.6.1.6 TASK FORCE FOR FUNCTIONAL LIFE TESTS OF DE-ENERGIZED TAPCHANGERS – Phil Hopkinson, Chairman

The Task Force on Life Tests, De-energized Tap Changers was called to order at 9:35AM on October 26, 2010. There were 40 attendees, 16 members, and 24 guests with3requesting membership. A quorum was not present. This TF has been in existence fora number of years. According to the roster there are 113 members. Regularattendance at meetings has been much lower – approx 25 members and 25 guests. Anopen action item from the last meeting is to send a message to the members using thelistserv to confirm membership on the TF. There are no formal procedures to confirmTF membership and it was suggested to look at the attendance from the last 2 meetingsand reset the membership. There were no patents to disclose. Reviewed the Agendafor the meeting, and the Minutes from the March 9, 2010, meeting in Houston, Texas,were approved.

1. The updated Dix slides on Test issues and results

Jeremy Sewell reviewed the updated Larry Dix presentation on Functional LifeTest. Extended discussion on the test and latest test results.

2. New Business


The meeting adjourned at 10:50 AM.

7.6.1.7 WORKING GROUP FOR REVISION OF C57.135, GUIDE FOR THEAPPLICATION, SPECIFICATION AND TESTING OF PHASE-SHIFTINGTRANSFORMERS – Jin Sim, Chairman

The Working Group met on Tuesday, March 9th, 2010 with a total of 13 in attendance.The group’s membership is 31 so a quorum was not reached. The latest draft had beendistributed to the group for a straw ballot and to the IEEE for editorial review and thecomments from those reviews were discussed. The group discussed all of the IEEErecommendations and as many of the technical comments as possible during themeeting time and the consensus opinions of those discussions will be submitted to thefull group via e-mail within the next couple of weeks for official resolution.

There were no objections to implementing all of the IEEE editorial review commentswhich covered standard formatting, the inclusion of an Abstract and Key Words,normative references and reference citations. All referenced citations will remain, butthe reference to IEEE 100 will be deleted and the other references that are to cited inthe body of the document will be moved from the Normative reference section to theBibliography. The discussions also led to a recommendation to include dual IEEE/IECstandard references for all reference citations in the text and to include the IECstandards in the Normative reference section as well.

Several graphical formatting issues and some figure numbering errors were pointed outby the straw ballot review and the group recommended their corrections. The use of theterms “primary” and “secondary” were questioned in the comments from the review andthe group recommended that the document be reviewed to be consistent in using “S”and “L” to describe the PST terminals and to only use “primary” or “secondary” wherethey do not refer to the PST terminals (such as “CT secondary wiring…”).

The discussions of the technical comments from the straw ballot review focused on theneed to include a requirement for the specifier to include any requirements that theymay have for phase angle shift under load. Further discussions showed that thespecification of phase shifting transformers has other criteria to consider as well,

particularly if the phase shifter is required to match the operating properties of otherPST’s for applications like parallel operation or replacement of existing units. Mr.Sanjay Patel volunteered to draft a paragraph to include under Section 4.8.1 and as abrief tutorial under Section 12.3 to cover the details.

Jin Sim, Sanjay Patel, Joe Watson and Tom Lundquist will discuss the few remainingtechnical comments within the next week via conference call and include furtherrecommendation for their resolution in the e-mail ballot.

Minutes TC-14 TAG Mar 10.doc

5. REVIEW AND UPDATE OF USNC ROSTERS FOR TC 14

Circulation of documents – there is limited circulation of documents beyond the official TAG members. This is to promote official membership in the TAG and there are copyright issues with the documents. There is a need to get the expertise beyond the official TAG members for some documents. Resource expert – the TAG has the ability to appoint 1 member as a RE. This is an expert whose expertise is essential for the TAG and is unable to pay the TAG fee. There is no RE currently appointed for TC14. Category D Liaison – there is an opportunity to establish Cat D Liaison between IEEE and specific IEC WGs/MTs. A request would be submitted by IEEE to IEC for approval. This is for active participation in an IEC WG/MT. Cat A Liaison – this liaison is for IEC and IEEE to share information only. It was noted that participating as a corresponding members on IEC Working Groups does not give any advantage for the work being done in the IEC. It is the same as a National Committee submitting comments but not attending the WG/MT meeting. One should to attend the Working Group meetings to influence the work.

6. 2010 PLENARY MEETING

The next meeting of TC14 will be held November 18-19, 2010 in Beijing, China.

14_659e_DA.pdf

A liaison in IEC may need to be established with TC9 for traction transformers. TC9 is revising a standard that may be of interest to TC14. Plenary 2011 – To be discussed in Beijing, but there will likely be a meeting in 2011. IEC General Meeting is scheduled for Melbourne, but there may be funding issues to travel for the officers/members. US may offer to host in Waukesha/Milwaukee.

7. STANDARDS ACTIVITIES

7.1 IEC 60076-1 Ed. 3.0 - Power transformers - Part 1: General (MT5 Convenor: P. Hopkinson)

There were some comments from IEC Central Office that were missed. Draft was updated and are waiting for French version of the document before it will be circulated as FDIS.

7.2 IEC 60076-2 Ed. 3.0 - Power transformers - Part 2: Temperature rise for oil-immersed transformers (MT6 Convenor: A. Bossi) There were some comments from IEC Central Office that were missed. Draft is being with the convenor for updating and will need the French version before it will be circulated as FDIS.

7.3 IEC 60076-3: Power transformers - Part 3: Insulation levels, dielectric tests and external clearances in air: (MT 60076-3 Convenor: Yukiyasu Shirasaka) Mr. Raj Ahuja is the US expert. 14/643/CD was circulated, next meeting will be in November in Beijing. It will likely take more than 1 meeting to address all of the comments.

7.4 IEC 60076-10 Ed. 2.0 - Power transformers - Part 10: Determination of sound levels (MT 60076-10 Convenor: Dr. C. Ploetner) IEC is addressing similar issues as IEEE. A report will be given at Ramsis Girgis’ meeting. European sound levels are generally lower than US. Noise abatement is an issue especially when transformers are installed in residential areas. At the Beijing meeting, discussion on guidelines for low noise transformers may need to be discussed. Low noise transformers are not required for all applications. There are no US experts for this MT. Ramsis Girgis and Jeewan Puri are experts for the TAG.

7.5 IEC/TS 60076-14 Ed.1.0 - Power transformers - Part 14: Design and application of liquid-immersed power transformers using high-temperature insulation materials (MT4 Convenor R. Marek) Upgrade the document from TS to IS. CD scheduled for January 2011, and the target date for publication as a standard is January 2013. First MT meeting was recently held, next meeting scheduled for mid 2011. This is similar to IEEE PC57.154, though there will be differences between both documents.

7.6 IEC 60076-16 Ed. 1.0 - Power transformers - Part 16: Transformers for wind turbines

applications (WG31 Convenor M. Sacotte)

WG recently met to complete addressing comments from CDV. If completed, next step will be to circulate as FDIS. No US expert identified. Document of interest to IEEE TF Wind Power Transformers.

7.9 IEC 60076-19 TS Ed.1.0 - Rules for the determinations of uncertainties in the measurement

of losses in power transformers (PT 60076-19 Convenor A. Bossi)

New project, gathering members. It is based on a CENELEC document and Mr. Jarman reports that it is difficult for manufacturers to comply. No US expert identified. Ramsis Girgis and Jin Sim should consider participating.

7.10 IEC 60214-1 Ed.2.0 - Tap changers - Part 1: Performance requirements and test methods

(MT 60214-1 Convenor A. Kraemer) Revision of document. 1st meeting on revision was in September. Main topic of discussion is resistor-type tap-changers. Next meeting will be December in Tokyo. Craig Colopy is the US expert.

7.11 IEC 61378-1 Ed. 2.0 - Convertor transformers - Part 1: Transformers for industrial applications (MT7 Convenor U. Piovan) Waiting for circulation as FDIS. Sheldon Kennedy is the US expert.

7.12 Future IEC 60076-XX: Power transformers - Part XX: Energy efficiency for distribution transformers

New project. Based on a CENELEC document, which includes efficiency tables. Not desired to have efficiency for US and the rest of the world, but need to make sure that the correct figures/parameters from the NCs are included. C57.12.90 has and Appendix with conversion parameters from 50 Hz to 60 Hz No US expert identified.

7.13 Other proposed standards

7.13.1 Proposal to adopt all parts of European Standard series EN 50216 - Power transformer and reactor fittings The Chairman suggested that either all parts of the EN 50216 series or none of the parts should be adopted. Most comments within 14/615/INF show that the majority of members are in favor of the adoption. All 16 parts of the EN 50216 series have been circulated to NCs asking for comments and a proposal for a Project Leader. It appears that these documents were fairly well received by the NCs and there will be further discussion in Beijing. These documents are old, but will be relatively unchanged if adopted by the IEC.

To be discussed in Beijing in November. Jin Sim agreed to convene the joint group, and USNC will need to formally nominate him as an expert. Most of the IEC members are also members of the IEEE Working Group involved in the revision process, so there will not be much work needed within IEC.

8. OTHER ISSUES

8.1 Scope change for TC14 and 60076-1 A proposed scope change is included in 14/662/INF. This will be discussed in Beijing in November. This is to clear up any confusion on certain issues on

8.2 IEEE C57.15-2009 - IEEE Standard Requirements, Terminology, and Test Code for Step-Voltage Regulators


7

Final IEEE standard was published in 2009 and was circulated to the NCs. 14/637/DC was circulated. 14/642/INF is the compilation of comments received. Further discussion will be held in Beijing in November. It was well received and will likely move forward within TC14. Need to confer with Jodi Haasz/Matt Ceglia.

8.3 SC 17C MT 27 of IEC 62271-211, "High-voltage switchgear and control gear – Part 211: Direct connection between power transformers and gas-insulated metal-enclosed switchgear for rated voltages above 52 kV"

The MT 27 of SC 17C has started the revision of IEC 62271-211 "High-voltage switchgear and control gear – Part 211: Direct connection between power transformers and gas-insulated metal-enclosed switchgear for rated voltages above 52 kV". There is no expert from TC 14 nominated to MT 27. It would be helpful if TC 14 could nominate an expert. At the first meeting the discussion found that besides single phase direct connecting from GIS to transformers today also three phase are used. In Asia there are newly on the market transformers with SF6 insulation. To cover this topic correctly TC14 is kindly asking for a transformer expert from MT 27. The question to TC 14 is if three phase transformer connections and SF6 transformers shall be covered in this standard.

8.4 Establishment for Category D liaison with IEEE

It was requested that a category D liaison be established with IEEE – Power and Energy Society Transformers Committee – with several WGs/MTs of IEC/TC 14. The meaning of Category D liaison is described in the ISO/IEC Directives Part 1 (1.18.3.1). IEEE will need to send a letter to IEC/TC 14 (Secretary/Chairman) requesting the liaison and giving reasons for this liaison. The IEC SMB would need to vote on the liaison. Delegates present were unanimously in favor of establishing this liaison. IEEE needs to identify the people who will serve as the Cat D Liaison before moving forward. The people will need to be willing to travel to the meetings.

8.5 JWG between IEC/TC 10 (Fluids for electrotechnical applications) and IEC/TC 14 to revise

IEC 61181 (Mineral oil-filled electrical equipment - Application of dissolved gas analysis (DGA) to factory tests on electrical equipment) and IEC 60076-2 (Power transformers, Part 2 Temperature rise for liquid-immersed transformers)

It was agreed to invite IEC/TC 10 to revise IEC 61181. A joint working group would need to be created and the US (Tom Prevost) will offer to lead this project or to assist in the development of the work. US to propose the revision.

9. NEW BUSINESS There was no new business.

9. DATE AND PLACE OF THE NEXT MEETING

The next meeting will be held in April, 2011, in San Diego, CA during the IEEE Transformer committee meetings.

9. ADJOURN

Meeting adjourned at 10:20 am.

Reported By: S. Choinski October 25, 2010

12.3. Cigré liaison Last Cigré session was held in Paris on the 25th of August with more than 300 attendees, which makes the transformer session one of the most popular in the event. A poster session was also part of the event with 29 selected papers in two time slots.

12.3.1. Paris session Discussion meeting summary • PS1 Transformer incidents in service

o Keynote speech by Mr. Fate (Ca) 50 % of fire caused by HV bushings Pressure relief device are of limited efficiency Mitigation measures includes tank designed for energy containment.

Nowadays tank can withstand up to 8 MJ, but considerable improvement can be made by enhanced tank design

o Discussions Other sources of critical incidents are reported as smoke, debris, fire

fighting water, oil spills and porcelain fragments, static electrification, seismic forces and resonance between cables and transformers.

France showed a fire rated of less than 0.015 % in the past 30 years due to transformer tank explosion. An extensive work with the manufacturer have allowed to correlate the arc energy and the tank pressure withstand supporting the work of HQ. Existing transformer being able of withstanding up to 2 bars and arc energy can be such as it develops 3 bars and more.

Were displayed as effective measure to reduce the fire risk, the use of RIP bushings, monitoring of tap changer, monitoring of moisture in the bushings

The advantage of high fire point liquid was highlighted as reducing the risk of explosion of pole type transformer, reducing the risk of fire in tap changers

• PS2 Transformer Life

o Keynote speech by Mr. P Jarman (UK) Assessment of remaining life is important for investment planning Unfortunately the current diagnostics methods give only a short notice

before failure. We still need a good aging indicator.

o Discussions Chemical indicator of ageing shall be carefully selected and their long-term

stability as well as the validation of the laboratory must be evaluated. The current DGA does not take into account the difference between free

breathing and seal type transformers. The Irgamet passivator seems to reduce by a factor 10 the amount of furan

dissolved in oil To estimate the remaining life the statistical approach is considered as a

valid way, as well as health index and risk index. Furan are not reported as a very accurate indicator but can be used to determine which units needs to be more carefully monitored. Methanol seems to be a promising new aging indicator.

• PS3 Transformer Modeling

o Keynote speech by Mr. Tenhbolen (D) 3 active areas of transformer modeling, Windings, 3D electromagnetic field

and CFD for hydraulic behavior. Nevertheless validation of such detailed model is absolutely necessary.

12.3.2. Next meetings

11th to 16th of September 2011 in Kyoto Japan • Preferential Subjects

PS1: Transformer Maintenance, monitoring, diagnostics and related testing o New approaches for maintenance, monitoring and diagnostics, development of

health index o Advanced monitoring technology and algorithms, example of early detection,

criteria o Low maintenance transformers, transformer improvements, etc.…

PS2: New material o New materials-compatibility, technical performance, economic value. o Ageing o Dielectric performances under unconventional stresses

PS3: Transient phenomena and testing

o In service experience, measurements, failures, lessons learned o Critical configurations, simulations, very fast transients, disconnector switching o Experience with transformer testing, improvements

Paris Session 2012

• Draft proposal of Preferential Subjects PS1: Transformer For the future network

o Monitoring, dynamic overloading, impact of harmonics

PS2: Eco design Eco use o Low noise, low losses, high temperature material, recycling, environmental
