ABSTRACTThe EPRI Transmission Line Reference Book: Wind-Induced Conductor Motion was published in 1979, and is still a well-used reference today. This book describes the mechanisms and control systems for the different forms of vibration of conductors, including fatigue of conductors, aeolian vibration, wake-induced oscillation, and galloping. Since its publication, there have been considerable developments in both approach and technology in this field. There is also a concern that the book is too academic and cannot easily be put to practical uses. To address these concerns and to meet current needs, the book will be updated. The objective of updating the book is to provide transmission and distribution line designers with the best practical tools to design overhead lines effectively in order to minimize damages to the lines from wind-induced conductor motion, and to provide overhead line maintenance staff tools to analyze vibration problems on existing lines for improvements of their performance related to such motion. Overall, the goal will be to provide the electric power industry with a useful and practical reference guide that will complement the new edition of the Red Bookthe EPRI AC Transmission Line Reference Book: 200 kV and Above. This report describes progress in 2005. Activities included development of a tender document, solicitation of proposals, selection and awarding of contracts to author teams, a kick-off meeting of lead authors to coordinate approaches to all chapters, and initial drafting of most chapters. Drafts of Chapters 2 through 6 were developed in 2005, and are included in this progress report in Appendices C through H. The drafts represent a substantial effort. In most cases, more than 60% of the drafting is complete. The draft chapters provide a clear indication of the direction and breadth of the revision, and of the areas of new information to be included. The drafts are, however, incomplete in some areas, and placeholder heading titles indicate where more information is to come in the future. With these draft chapters, this report provides readers with a preview of the revised edition of the Orange Book, which will be published in final form in 2006. Applets will be developed in 2008, if funding allows. A Readers Survey is provided with this Progress Report on page vii in order to obtain feedback and comment from funders on the draft chapters.

1BACKGROUNDIntroduction EPRI is sponsoring development of a new edition of the Transmission Line Reference Book: Wind-Induced Conductor Motion, commonly known as the Orange Book, which was originally published in 1979. Development of a new edition is being undertaken for several reasons. First, while the book is still a well-used reference for conductor vibrations, it is now almost a quarter of a century old. Since its publication, there have been considerable developments in both approach and technology in this field. Second, there is also a concern that the book is too academic and cannot easily be put to practical uses. To address these concerns, revision of the book will update existing information in the Orange Book to reflect the state-of-the art knowledge in the field of wind-induced conductor motion. The revision process will also add new information to the book to cover topics, interests, and technology that have been developed since the book was last published. In addition, the revision will broaden the scope of the book to acquire global utility experience in conductor motion. As regards practicality, the audience for the book consists of transmission and distribution line designers and staff responsible for maintenance of overhead lines, interpretation of line failures, and correction of poor designs. The objective of this revision project is to provide them with the best practical tool to design overhead lines effectively in order to minimize damages to the lines from wind-induced conductor motion, and to analyze existing lines for improvements of their performance related to such motion. The new edition will include examples to facilitate the understanding of wind-induced conductor motion and the application of the knowledge to practical uses. Usability of the volume will be improved with inclusion of an index, applets (small computer calculation programs), and other suitable electronic media. Overall, the goal will be to provide the electric power industry with a useful and practical reference guide that will complement the new edition of the Red Bookthe EPRI AC Transmission Line Reference Book: 200 kV and Above. This section describes the general approach that is being taken to revise the Orange Book and the implementation plan. Approach The strategy for the revision of the Orange Book has been to assemble a team of world experts to update different chapters of the book or to write new chapters to cover advancements in technology in this field. The overall timeframe for the project will be approximately three years. At the start, a preliminary review of the book was carried out to identify the scope of revisions and to identify potential authors for the revisions. The list of potential authors was further1-1

augmented through personal contacts, referrals, and national and international committees related to the subject. It was decided that work would be divided into chapters, and that the revision of the chapters would be tendered. The identified experts on the prepared list would be invited to submit proposals. The proposals submitted by the bidders would include recommendations for the revisions to be carried out. It was further decided that an expert would be selected through the tender process to be the lead author of each chapter. This author will have overall responsibility for the update or creation of that chapter. Forming a team among experts to complement one anothers skills would also be acceptable. The selection of experts will support a balance between academics and practitioners. To ensure the quality of the finished product, another expert in the same field would be selected to review each chapter for technical accuracy. The draft would also be submitted for peer reviews by representative end-users. An expert would not be assigned to undertake the writing of more than one chapter. However, he or she can be the reviewer of other chapters. In addition, an Editorial Committee was formed to ensure the revised Orange Book will be completed according to the projects goals, to review the technical contents, and to ensure consistency of style and format among different chapters. The Committee consists of four individuals. The Project Manager is John Chan of EPRI. The Technical Assistant is David Havard of Havard Engineering Inc., who has extensive experience in wind-induced conductor motion and is well known in the field. The Technical Consultant is Charles Rawlins, who also has a long background in the field and was one of the authors of the original edition. The Editorial Assistant is Jonas Weisel, who has more than 25 years experience in technical writing and editing, particularly in the electric utility industry.

Implementation Plan Revision of the Orange Book is following the two-phase process outlined below (also see Figures 1-1 and 1-2):

1. Development of Tenders and Awarding of Contracts Initial Scoping and Solicitation of Interest Preparation of Technical Update Report Finalizing of Scope and Authors

2. Production Process Review of Current Edition and Recommendations for Revision Writing and Review Editing and Publication

In 2005, as noted in Section 2, the tender was prepared and issued, and contracts were awarded (Tasks 7 and 8 in Figure 1-1). Also, in 2005, an initial meeting of lead authors was held, and first drafts of most chapters were written (Tasks 1 through 3 in Figure 1-2).

Overall Scope and Structure of the New Edition The revised edition of the Orange Book will include a re-ordering of the sequence of chapters and two new chapters, as shown in Table 1-1.Table 1-1 Revised Table of Contents Current Edition Chapter No. 1 2 3 4 5 Title Introduction Fatigue of Overhead Conductors Aeolian Vibration Galloping Conductors Wake-Induced Oscillation Chapter No. 1 2 3 4 5 6 7 Title Introduction Aeolian Vibration Fatigue of Overhead Conductors Galloping Conductors Bundle Conductor Motions Overhead Fiber Optic Cables Transient Motions Glossary Index Revised Edition

The re-ordering of Chapters 2 and 3 in the revised edition is intended to explain more about the phenomenon of vibration before discussing the effects of vibration. The new Chapter 6 will provide information on fiber optic cables, which have come into use since the earlier edition. It will include a review of the types of cable construction, attachment hardware, aerodynamic problems that can occur, qualification test procedures, and field experience. The new Chapter 7 will cover transient motions, which include short circuit forces, bundle rolling, ice drop, gust response, and wind action on members. While some of these topics were briefly mentioned in the earlier edition, experience in the intervening years offers new insights on these phenomena. It was also decided to include, where available, case study information on utility field experience. In addition, while the focus of the book will be on overhead transmission lines, discussion will also be included, when relevant, of distribution lines. A glossary and index will also be included in the new edition. There was agreement that applets, or small computer programs, will be incorporated with the new edition of the Orange Book for the purposes of providing users with simple calculation tools needed to assess different aspects of line vibration. The subtitle of the book will be changed to: Transmission Line Reference Book: Vibration and Dynamics of Overhead Conductors. Applets will be developed in 2008, if funding allows.

2ACTIVITIES IN 2005Introduction In 2005, the primary activities included development of a tender document, awarding of contracts to author teams, a kick-off meeting of lead authors to coordinate approaches to all chapters, and initial drafting of chapters. The direction for these activities was provided in two meetings. In February, the Editorial Committee met in Las Vegas, Nevada, to draft a tender document and discuss the process of soliciting bids and awarding contracts. Following issuing of the tender in March and awarding of the contracts in April, a meeting of the lead authors and the Editorial Committee was held in May in Toronto, Canada. This meeting was intended to determine the scope of each chapter and to coordinate writing. Work on the first drafts of chapters was initiated following the May meeting, and the first drafts are incorporated in this progress report as Appendices C through J. Other activities were carried on during the year to solicit further interest in and funding for the project. Section 2 describes activities conducted in 2005 to revise the Orange Book. Development of Tender and Awarding of Contracts It was decided that the authors to revise the Orange Book should be selected through a competitive bidding process. Accordingly, EPRI issued a formal Request for Proposal (RFP) in February 2005 for revision of Chapters 2 though 7 of the Orange Book. (Chapter 1 and the end matter [Glossary and Index] will be prepared by the Editorial Committee.) The RFP, or tender document, was sent to more than 30 individuals with expertise in this area and interest in contributing to the book. (A copy of the tender document is included in this report as Appendix B.) The tender document requested that bidders submit proposals for revising one or more specific chapters. (Bidders could bid on more than one chapter, but only one chapter would be awarded to any bidder.) Bidders were asked to bid as individuals or as part of a team. Team members could include a lead author and one more team members, who could serve as co-authors or resource persons. A statement of qualifications was required for each member of the team. Bidders were also required to comment on the suggested approach to each chapter as reflected in skeleton outlines, which had been prepared by the Editorial Committee. That is, bidders were to indicate what they would do in addition to, or differently from, the skeleton outline. Further, bidders were required to provide a cost estimate for writing the chapter and attending meetings. The deadline for proposals was March 28, 2005. In response to its RFP, EPRI received a number of bids from qualified experts in the field. However, in all but one case, these bids were significantly over the anticipated budget for the

2-1

work. It was possible that the tender document may have unintentionally misled bidders as to the required size of writing teams and thus, the budget available for the project. As a result, in order to develop the revised edition with the available funds, EPRI subsequently assigned fixed-price budgets to the six chapters being revised. These budgets were weighted relative to the expected level of effort, and were consistent with budgets for other EPRI books under revision. Consideration was given to the expected length of each chapter and whether it is new material or an update of existing material. Bidders were asked to notify EPRI by late April 2005 if they were interested in proceeding with revision of the chapters under the fixed-price budgets. An acceptable agreement was made with lead authors for every chapter. Successful candidates were invited to a kick-off planning meeting in May 2005 (see below). Assignments were subsequently made as follows: Chapter Chapter 1, Introduction Chapter 2, Aeolian Vibration Chapter 3, Fatigue of Overhead Conductors Chapter 4, Galloping Chapter 5, Bundle Conductors Chapter 6, Overhead Fiber Optic Cables Chapter 7, Transient Motions Glossary/Index Authors Meetings and Conference Calls Kick-off Meeting A kick-off planning meeting was held in Toronto, Canada, on May 24-25. The meeting brought together lead authors for the chapters and the Editorial Committee. Attending were John Chan, EPRI; Louis Cloutier, University of Sherbrooke; Anand Goel, Hydro One; Dave Havard, Havard Engineering; Jean-Louis Lilien, University of Liege; Craig Pon, Kinectrics; Chuck Rawlins, Consultant; Jeff Wang, ETS; and Jonas Weisel, Jonas Weisel & Associates. The purpose of the meeting was to discuss how the group could work together to revise the Orange Book. The meeting primarily consisted of presentations by each of the lead authors to explain their approach to their respective chapter and areas where their approach might diverge from the approach proposed by the Editorial Committee. Presentations were made on Chapter 2 by Chuck Rawlins (for Giorgio Diana who was unable to attend); Chapter 3 by Louis Cloutier; Chapter 4 by Jean-Louis Lilien; Chapter 6 by Jeff Wang; and Chapter 7 by Anand Goel and Craig Pon. (Following the meeting, Claude Hardy agreed to act as lead author for revision of Chapter 5.) It was agreed that first drafts of the chapters would be completed by October 15, 2005, for inclusion in this progress report. Charleston Meeting A number of members of the Editorial Committee and the authors met in conjunction with the Conductor Dynamics Conference in Charleston, South Carolina on September 22, 2005 to review progress on the book. In discussion, it was decided to provide utility funders of the Orange Book project with a survey form, where they could provide feedback on the revision2-2

draft on issues such as whether the book is covering areas of interest to the users and where more information is needed. Conference Calls Conference calls were held on August 8 and October 25, 2005 to review progress on the book. Minutes are included in Appendix A of this Progress Report. Drafts of Chapters Drafts of Chapters 2 through 7 were developed in 2005 and are included in this progress report in Appendices C through I. More information on the status of the drafts is provided in Section 3 of this progress report. The drafts are intended to represent an initial start. They are incomplete in some areas, and placeholder heading titles indicate where more information is to come in the future. The drafts have not been reviewed by peer reviewers or the Editorial Committee. They have also not been edited or formatted in the form in which they will be published. The chapters are scheduled to be completed, reviewed, edited, and formatted in 2006. Solicitation of Interest A number of activities were undertaken in 2005 to solicit additional interest from utility funders and from potential authors of the book: Magazine Article. An article entitled Shake and Break: Diagnosing and Preventing Damage Caused by Wind-Induced Conductor Motion was written by John Chan and Jonas Weisel for possible publication in a trade press magazine. The article describes the Orange Book and its revision, as well as recent application of the book by two utilities (Bonneville Power Administration and Arizona Public Service). The article was submitted to T&D World Magazine on September 19, 2005. Presentations to Task Force. Presentations on the Orange Book were made to the EPRI Overhead Transmission Inspection & Maintenance Task Force on April 6-8, 2005, in Charlotte, North Carolina, by John Chan and on August 16-18, 2005, in Denver, Colorado, by John Chan and Dave Havard. The presentations described the goals of the revision, the approach, and the progress to date. CIGRE Meeting. On April 27, 2005, in Bilbao, Spain, Dave Havard made a presentation on the Orange Book to a meeting of the CIGRE Working Group 11, Mechanical Behavior of Conductors and Fittings.

3PROGRESS AND FUTURE PLANSIntroduction Significant progress was made in 2005with lead authors and writing teams selected, and initial drafts of six chapters written. A complete version of the revised book is planned to be made available by the end of 2006. Progress Drafts of Chapters 2 through 6 were developed in 2005, and are included in this progress report in Appendices C through H. The drafts represent a substantial effort. In most cases, more than 60% of the drafting is complete. The draft chapters provide a clear indication of the direction and breadth of the revision, and of the areas of new information to be included. The drafts are, however, incomplete in some areas, and placeholder heading titles indicate where more information is to come in the future. In addition, the draft chapters have not been reviewed by peer reviewers or the Editorial Committee, and have also not been edited or formatted in the form in which they will be published. As noted below, the chapters are scheduled to be completed, reviewed, edited, and formatted in 2006. Future Plans A meeting of the lead authors and the Editorial Committee will be held January 26-27, 2006, in Albuquerque, New Mexico. The meeting will review the draft chapters, decide on work remaining to be done, and establish a production schedule for the rest of the year. Once the draft chapters are completed, they will proceed through steps 4 though 7 in the production process as outlined in Figure 1-2 of this progress report. The chapters will be reviewed by peer reviewers and the Editorial Committee, and will be copyedited and laid out. Chapter 1, the Glossary, and the Index will be prepared by the Editorial Committee. An electronic version of the revised edition will be available the end of 2006. A hard copy will be published in 2007. Applets will be developed in 2008, if funding allows.

AMINUTES OF MEETINGS, 2005Meeting Minutes Orange Book Editorial Committee Third Meeting February 3-4, 2005 Gold Coast Hotel and Casino Las Vegas, Nevada Attending: John Chan, EPRI Dave Havard, Havard Engineering Chuck Rawlins, Consultant Jonas Weisel, Jonas Weisel & Associates Thursday, February 3, 2005 John opened the meeting and welcomed the members of the Editorial Committee to the Committees third meeting. He noted that they had last met in August of 2004 in Toronto. He said all the groundwork for development of the tender had been completed last year, and summarized in the Technical Update report published in October 2004. The key achievement of this meeting will be to write the tender document. Due to limited funding of the project, it will not be possible to fund completion of the book in 2005. There are several ways to approach the writing. For example, the project could sponsor the writing of just a few chapters this year. However, John said he believes that the better way to proceed is to begin on all chapters this year, even though they will not be completed. In keeping with the Committees pattern of holding alternate meetings in the West and in Toronto, the next meeting will be in Toronto. That meeting could be the first meeting of the authors who have been chosen to write the book. By the time of the next meeting, the authors will have been selected and ready to begin writing. The meeting could be a session for lead authors to present their plans for chapters and to obtain broad consensus for the books direction. John sketched out a preliminary schedule. The tender could be issued by February 21. Bidders would have four to five weeks to reply, so bids would be due by March 28. The Committee would have two weeks to review bids. (The Committee would meet by conference call or webcast.) Winning bids would be announced by mid-April or the end of April. The next meeting could be held May 16-17 or May 24-25. Guests: Mark Orth, Arizona Public Service Anand Goel, Hydro One (Friday only) Craig Pon, Kinectrics (Friday only)

John referred to the meeting agenda (see attached). 1. Outstanding Items from Last Meeting. Jonas made a presentation on three editorial issues raised in the previous meetingobtaining a Word version of the first edition of the Orange Book, developing a magazine article, and revision of the Authors Guide. Word Version. At the previous meeting, the possibility was raised of locating or creating an electronic version of the first edition. The idea was that it might save authors of some chapters the need to re-produce any material that was not necessary to change. It might also be possible to locate some of the original photos. After some research, Jonas found that the publisher of the first edition no longer exists and that EPRI does not have the original files. EPRI does have a pdf file, but not a Word version of the first edition. The cheapest way of generating an electronic version would be to have the book re-keyed. It would cost $6 per page x 240 pages = $1,440. Dave estimated that about 50% of the book was still valid and worthy of being re-keyed. John said it might be easiest, given the cost, just to go ahead and have the whole book re-keyed. Dave asked if it might be possible to use some of the photos from the first edition. Jonas said he could try scanning some of the photos, which was done for the Red Book, and see what the quality is like. Magazine Article. Jonas noted that in the last meeting the Committee had discussed the possibility of having an article about conductor vibration placed in a trade magazine such as T&D Magazine. The article would describe a utility vibration problem (a case study), and would be used to help generate interest in the Orange Book and possibly attract additional funders. The original concept for the article was to describe a case where a utility initially did not know that they had a vibration problem. They were discovering broken strands and replacing conductors, and only later associated it with vibration. Following the Task Force meeting last fall, John and Dave suggested that Jonas start with BPA. Jonas interviewed BPAs Jerry Reding. The main area discussed was a large program to replace two types of failing devices (spring-type spacer dampers and steelcoil twin spacers) (about 100,000 units of each). Jonas pointed out that this is a different concept than the one described above. John said that was OK since the BPA problem is actually typical of many utilities. Mark described a recent vibration problem at APS. On one of the utilitys lines, bolt failures were occurring, causing outages. The line is in wide open terrain, without wind breaks. A root cause analysis showed that the failures were a result of excessive cyclic loading. Previous conductor field tests indicated the loading was about 10 pounds. But lab tests indicated the bolts should handle at least 100 pounds. As a result, the research focus shifted to insulators. Subsequent field tests showed that insulator loading was 50120 pounds. The utility is still investigating why the amplitudes are so great. But the solution was to add dampers. Use of the dampers has stopped the occurrence of outages. Mark said, Without the Orange Book, we would not have known what to do.

Jonas took a copy of Marks PowerPoint presentation and agreed to interview Mark by telephone later in order to get more details and to develop an article. Dave also suggested that Jonas contact Ed Busse of Consolidated Edison about a galloping issue. Authors Guide. Jonas said he had revised the Authors Guide, based on Daves email of 11/30, primarily to revise the section on SI units to make it more specifically relevant to the Orange Book.

2. Plan for 2005. Funding. John said the available funding for writing in 2005 would be $100K. John suggested that the project aim to do all chapters at once. If the chapters are not complete in two years, the project will be extended to a third year. The contracts issued this year will be contingent on being extended to 2006. John said bids should give the total price that would be spread over two years. Deliverables. Deliverables this year will include Vibration software 3.0, which will be completely re-vamped. Chuck raised the issue of whether it will be compatible with whats in the Orange Book. John said that he would provide information on the algorithm used in Vibration Software 3.0 to Chuck and Dave for their review and comment. The other deliverables this year will be drafts of the chapters. An EPRI draft report is due October 30, 2005. The report will be a progress report on the project. It will include actual drafts of the chapters. The deadline for authors will be October 12, 2005. The chapters may be incomplete, and include chunks of the first edition. Schedule of Activities. John referred to the schedule noted earlier for writing, issuing, and reviewing the tender and awarding the bids. Dave noted that there will be a Cigre meeting in Bilbao, Spain on April 25-27. 3. Tender Document. John led the committee in a drafting of the tender document. John suggested that the cover letter be very brief and just identify the attached documents. Attached documents will include the authors guide, the skeleton outline (both overview and detailed), and a list of technical references. The cover letter should also include directions to the FTP site, where there would be a pdf copy of the first edition. Dave noted that the bidders will have to receive a list of all the other potential bidders, so that interested parties could form teams. Dave asked that a definition of applets be included and that bidders understand that they would not be required to develop applets themselves but would be asked to identify topics for applets. 4. Chapter Drafts. John said that the tender should make clear that only Chapters 2-7 are open for bids. Chapters 1 and 8 will be written by the Committee. Drafts of chapters will be scheduled to be included in the EPRI report to be published in October 2005.

5. Legal Issues. Jonas presented a summary of a meeting held on January 25, 2005 with John and Kevin Chu, one of EPRIs attorneys. The meeting covered copyright and legal issues raised in the August 2004 Editorial Committee meeting. Jonas gave the Committee a transcript of the conversation. The conversation covered: use of copyrighted data in figures, use of informal conference papers, discussion in the Orange Book of manufacturers products, and contractor agreements with the authors. 6. Conflicts of Interest. John discussed the need for the Committee members to sign EPRI forms for conflict of interest.

Friday, February 4, 2005 John recapped what had been discussed the day before, and reviewed the proposed schedule for development and issuance of the RFP. He said the group should aim to complete a draft of the tender by the end of the days meeting. John noted that only lead authors will need to attend the meeting in May in Toronto. He said that it should also be clear the contracts will be held by the lead authors, and that lead authors will be responsible for their teams. John said that, if not enough lead authors bid on the project, the Committee will put together teams. John said that limited funding is available for the project, and the tender should say that cofunding is a factor in selection of bidders. Cofunding could be in the form of reduction in hourly rate, funding from other organizations, or support from external sources. The group worked throughout the morning and early afternoon to complete a first draft of the tender. Jonas said he would take the draft and refine it and have it ready for review by the Committee by February 11. He and John would meet on February 15 in Palo Alto to finalize the tender and arrange for it to be released. John will set up a meeting so that there can be coordination of the development of the software and the Orange Book. It is important that the algorithm used in the software and that found in the text are consistent. The meeting was adjourned in mid-afternoon. Prepared by: Jonas Weisel

Tuesday, May 24, 2005 Project Background: John Chan John welcomed the attendees, and initiated introductions around the room. He said the purpose of the meeting was to discuss how the group could work together to update the book. The key part of the meeting will be presentations by each of the lead authors on their respective chaptersto indicate their planned approach and any deviations from the outline (skeleton) already developed. Lead authors have been identified for nearly all the chapters. For those chapters presently without lead authors, the group will discuss the best way to proceed. As regards the budgets, John said that EPRI funding is purely from its members. Funding for revision of the Orange Book is restricted to those dollars specifically assigned to the book and is very limited. He requested that authors bill half their budgets this yearby early December 2005. Otherwise the budget will be lost. John reviewed the history of the project thus far. He had contacted Dave early on to discuss the best approach to revision, and then met with Chuck and Jonas to form an Editorial Committee. In the first year of the project, they reviewed the first edition and identified sections to be added, removed, and revised. This constituted the skeleton outline for the book and the proposed revision plan. They identified experts in the areas covered by the book, who could be candidates for the updating process. It was decided to go out for bids in order to identify as many experts in the field as possible. Editorial Issues: Jonas Weisel Jonas reviewed the Authors Guide, which is a short guidebook that sets some ground rules for the production process, setting up files, formatting parts of the book, etc. A copy of the Authors Guide will be posted on the FTP site. Key points: Drafts should be reviewed by the technical reviewers, including the teams technical reviewers, outside reviewers, and users before the book is submitted for production. Figures, tables, and equations are numbered by section, not just chapter. E.g., the fifth figure in the fourth section of Chapter 3 is Figure 3.4-5. Reference format is author-date, not numbered footnotes. Authors need to keep a list of text, tables, figures, and photos reproduced from other sources, so that the production team may request copyright permissions. SI units should be used with English measures in parentheses. The production team can assist authors by providing a Word version of the first edition and by re-drawing or improving figures, as needed. Figures will be printed in black and white. Figures (especially graphs) relying on color coding should be avoided. The CD may include color photos.A-7

Dave asked if the differently sized European page would be an issue for production. Jonas said he would check on that. Jean-Louis asked if it would be possible to use material from an upcoming CIGRE brochure. Jonas said that CIGRE had given permission to use their material in the EPRI Red Book, which is being published this year. But he would discuss the issue with the EPRI attorney. Overview on Assigned Chapters: Dave Havard and John Chan Dave made an overview presentation on progress to date on the revision. He proposed a new title Transmission Line Reference Book: Vibration and Dynamics of Overhead Conductors. The group approved this title. Dave reviewed volunteers who have offered to contribute, progress to date, and changes to each chapter. The question was raised about whether station buses would be covered. Two issues are: vibration of tubular bus due to vibration and the forces due to short circuits on twin buses. It was agreed that it might be covered in Chapter 7, Transient Motions, or possibly in an appendix to the book. John reviewed the contracting procedure. He will draft a simple statement of work, and all lead authors will receive a contract with standard terms and conditions. Chapter 4, Galloping: Jean-Louis Lilien The authors in the team will include Dave, Chuck, and Pierre van Dyke. More external reviewers are needed, particularly for Sections 4 and 5possibly someone from the European group or the Japanese. They can be identified next year. Team members may meet in conjunction with the Cable Dynamics Conference in September 2005. Deviations from skeleton outline: Refer to CIGRE activity. Include worldwide data. Add torsional stiffness. Add aerodynamic drag damper. Add galloping parameters. Aerodynamic curves with real ice. New design of clearances. Tension variation. Mode superposition. Test results at test stations.

A-8

Jean-Louis raised concern over the ability to obtain permission to use CIGRE material. The Orange Book and an upcoming CIGRE brochure will be complementary. The need to obtain permission needs to be discussed at top levels. Dave will give Jonas name(s) of contact persons at CIGRE. Norman Bell is head of the committee (Committee B2- Publication &Tutorial Advisory Group [bell.normand@hydro.qc.ca]). Jean-Louis said he could provide a video of galloping to be included in the CD accompanying the book. Issue was raised about how much to say about hardware. It was agreed that it is OK to say that if you use this type of device, you will have this effect. OK to describe applications that have been made, tests that have been done. Give references. Should we discuss why were NOT using some devices? No. Authors can list devices from CIGRE survey. Authors should also flag areas that may be sensitive, so that the Editorial Committee can look at them and make determination. Craig asked if we should provide procedures that users could apply. John showed the group a format in the new EPRI Red Book, where an author had included detailed procedures. This would be OK. Jean-Louis asked if there can be blocks of text set aside for detail. Jonas suggested that the format incorporate sidebars. Chapter 3, Fatigue of Overhead Conductors: Louis Cloutier The authors will include Alain Cardou and Sylvain Goudreau. Louis said that the chapter will indicate that fatigue mechanisms could take into consideration the geometry of the conductor. His team is starting to do tests on conductors with different geometries to see if geometry has an effect. They will not have results for two years. For this book, they will provide preliminary results. Deviations from skeleton outline: Include fatigue of conductor clamp systems. More importance to Yb as a practical indicator of fatigue performance. Include fatigue measurement test methods. Include several test performed to establish the relative performance of different systems.

Issue raised about how to resolve differences of opinion that may arise between authors and reviewers. John said Editorial Committee will resolve. Issues raised about several contractual Terms and Conditions: 2.02 ix. Can we use proprietary material if we get permission? (Jonas will ask attorney.) 7.08. Export laws (Probably OK. Jonas will ask attorney.) 7.06. Insurance. (EPRI will waive this.)

A-9

Chapter 6, Overhead Fiber Optic Cables: Jeff Wang The authors will include Craig Pon and Tony Gillespie. Deviations from skeleton outline: Add hardware of fiber optic cables. Combine 6.2, Dampers and 6.5 Damper Types. Discuss damper installation locations.

In discussion the point was made that there is no agreement in the industry on damper installation locations. CIGRE has done a survey that could be used. But it was suggested that the authors do their own questionnaire and survey of utilities and manufacturers, using a targeted mailing list. It is not necessary to obtain results by October 2005. Wednesday, May 25, 2005 Chapter 2, Aeolian Vibration: Giorgio Diana Chuck Rawlins presented this presentation for Giorgio Diana, who was unable to attend the meeting. The authors will include Umberto Cosmai, David Hearnshaw, Andre Laneville, Alessandra Manenti, and Konstantin Papailiou. (Giorgio Diana will coordinate the chapters. David Hearnshaw will check the English usage.) In discussion, the need was expressed for utility reviewers. Possible reviewers include Tony Gillespie, Andre LeBlond, Jim Duxbury, Bruce Freimark, Robert Kluge, Jerry Reding, and Ming Lu. Anand will contact Jim Duxbury. Craig will contact Jerry Reding. Deviations from skeleton outline: Add concepts of modes of vortex shedding. Add mechanics of bundle conductor motions. Add data relevant to vortex shedding from dynamic bundles. Add new data on wind power input. Add section on modeling. Maintain discussion on spacer-damper requirements. Add new CIGRE recommendations on safe tensions for damped and undamped bundles. Add a short section on the expanded bundles vibration problems.

Chapter 7, Transient Motions: Anand Goel Anand will be the lead author for this chapter, with assistance from Craig Pon and Masoud Farzaneh. Areas: Short-Circuit ForcesCraig, Jean-Louis, Anand Bundle RollingJeff, Dave Gust ResponseJapanese researchers, Giorgio, Southwire Book (Dale Douglass) Wind Action on MembersManitoba Hydro, Louis, ITC, Dave Noise from WindJeff, Manitoba Hydro EarthquakesLouis Corona induced vibration Masoud Station BusAnand, Dave; Chuck will review CIGRE papers.

Anand, Craig, and Dave will discuss cases of member failures. Can collect data on this. Anand also has data on bus vibration. Chapter 5, Bundle Conductors: (To Be Determined) John will contact Claude Hardy to see if he will participate in the revision. Chapter 1, Introduction: Editorial Committee Work will begin on this chapter this year, time permitting. Miscellaneous Problems. Dave requests that members of the group send him photos or videos of problems that he can show to the EPRI Task Force in August to spur interest in the revision of the Orange Book. FTP Site. John asks Jonas to arrange for setting up the FTP site. New chapter numbers will be used. Folders will be set up for each chapter. Filenames will have this format: Section number, authors last name, month and day. For example: Section 3.3 Havard June 26. Classification of Information. Chuck suggests that the authors develop a system of classification of information in the book with regard to levels of accessibility, accuracy, and usefulness. All chapters will use the same terms and possibly have a box or italic text to designate it. Chuck will develop a memo for review by the Editorial Committee. (Subsequent to the meeting, a draft memo was received by the Editorial Committee.) PowerPoint. Craig asks Jonas to prepare a PowerPoint presentation on the Orange book revision for presentation at a June IEEE meeting in San Francisco.

Introduction John opened the conference call and reviewed the agenda, including status of contracts, progress of work to date, contents of the progress report, and invoicing practices. He said he would summarize the invoicing procedure in an email, as well. He reminded authors that the purpose of this revision is not only to update the book, but also to provide a practical tool that is useful to design engineers, with relevant examples. Contracts Diana. Contract emailed August 5. Has been received. But it is in the name of Giorgio Diana, and should be assigned to Politecnico di Milano, Departimento di Meccanica. (Subsequent to the conference call, John forwarded a revised contract the week of August 8.) Laval University (Louis). Contract faxed July 29. Everything is in place and ready to go. Okay to send invoice for the first $10K. Jean-Louis Lilien. Contract emailed August 5. Looks OK. Claude Hardy. Signed and returned contract July 8. Requested a return confirmation from Kristine Dulay at EPRI. Has not received it. (Subsequent to the conference call, John arranged for Ms. Dulay to send confirmation to Claude.) Jeff Wang. Received contract last week of July Signed and returned to EPRI. Anand Goel. Will have contract next year. Writers have volunteered to write sections. John said there is a small amount of money available for Chapter 7 this year, and he will discuss this off-line with Anand. Louis found a writer who will write one section. John suggested that Louiss writer contact Anand to see how much is available for this. Kinectrics. A contract will be issued next year. Progress Report John and Jonas will write this report, and have started working on it already. The report will give some background on the project and what work has been done this year. The chapter authors should just submit whatever they have written for their chapters by October 15. It is not necessary to send any information on their progress or budget. The drafts may be partial drafts. If you have not included or completed a section, just identify the heading title and say, To Be Completed. Status of Work Chapter 3 (Louis Cloutier). Each of the three authors is working on his own, re-reading the existing chapter. When Louis returns from holidays, they will meet and review what they have to do. Will decide issues, such as whether they continue to use fymax or yb. Will work on it later in August. They need to determine where the new data arefor example, Dave Sunkle on special support. But they expect no problems. It will go rapidly once they resolve a few issues. Expect to have no difficulty in meeting the deadline. Chapter 2 (Giorgio Diana). The authors have already met and decided how many paragraphs in each section and the contents of the sections. Expect to be able to meet the October deadline. Chapter 4 (Jean-Louis Lilien). Have three authorswaiting news from the other two (Dave and Pierre). They have revised the introduction and started the overview. Sees no problem in

A-15

getting a first draft by mid-October. But Jean-Louis is very concerned about copyright issues concerning information that overlaps with an upcoming CIGRE brochure that is being written by Pierre Van Dyke. They need agreement as soon as possible. Jonas said he has contacted the EPRI lawyer who recommended that we apply to CIGRE for permission for this specific case (even though CIGRE gave EPRI blanket permission to use their documents in the EPRI Red Book). Jonas will submit request to Catherine Ott at CIGRE. Chapter 5 (Claude Hardy). They did a lot of preparatory work while working out the proposal. Have also done a good proportion of the reduction work. Have drafted two sections and one subsection. With confirmation of the contract, they will launch the rest of the work. Claude asked for a clarification concerning spacer damper requirements, as noted in the minutes of the May meeting in Toronto. He said that he assumes that spacer damper requirements will be covered in Chapter 5, and that spacer dampers will only be covered in Chapter 2 from an Aeolian vibration perspective. John suggests that Claude confirm this with Giorgio. Chapter 6 (Jeff Wang). Jeff said that they have already started work on the hardware. Have contacted the hardware manufacturers to get the updated information regarding the fiber optic cable hardware, especially on the damper installations locations. There is no industry standard. Tony has some input on this, and they will include that. By October 15, they should be able to finish a partial first draft. Craig said the outline for this chapter developed by Dave and Chuck is a good start, but the scope may extend beyond that. Before they get into the details of writing, they will need to clarify the scope. When Jeff returns from China, he will put together a new table of contents and discuss with Craig and Tony. Chapter 7 (Anand Goel). They have received input from the contributors of what will be in the various sections. Anand sent an email showing the contents for each of the nine sections. They expect to have two sections by October. For those sections that are incomplete, will just put in headings. Jean-Louis asked if the bundle rolling section was on dynamics or torsional stiffness. Jeff said it will basically be on dynamics, but in order to describe the mechanics, they will need to introduce the torsional stiffness theory of the bundle. Chuck said it should also include static considerations. Jean-Louis said he will cross-reference Chapter 7 to refer to torsional stiffness, but not include a lot of detail, which will be in Chapter 7. Jeff will write the section in Chapter 7.

Miscellaneous Word Versions of Chapters. Jonas said that Word versions were developed of the chapters in the existing edition. These were sent to the authors and posted on the FTP site in early June. If anyone has any questions, they should contact Jonas. FTP Site. Jonas said an FTP site was set up. It requires no username or password. It can be used to upload or download files. When authors complete their drafts, they can upload them to the FTP site. European Page Size. Jonas said that, at the Toronto meeting, Jean-Louis asked if this is a problem. Jonas said he checked on this, and EPRI Publications said that this is not a problem. Availability to Students. Jean-Louis asked if the completed book would be available to students. John said it would be available at a nominal price.

Minutes of Orange Book Conference Call October 25, 2005 Attending: John Chan, EPRI Louis Cloutier, University of Sherbrooke Giorgio Diana, Politecnico di Milano Masoud Farzaneh, University of Quebec, Chicoutimi Anand Goel, Hydro One Sylvain Goudreau, Laval University Claude Hardy, Claude Hardy International Dave Havard, Havard Engineering Jean-Louis Lilien, University of Liege Craig Pon, Kinectrics Chuck Rawlins, Consultant Jeff Wang, ETS Jonas Weisel, Jonas Weisel & Associates

Summary of Main Points Next Meeting. The next meeting will be held in Albuquerque, New Mexico, on Thursday and Friday, January 26 and 27, 2006, to follow the IEEE meeting being held earlier that week. The meeting will be two full days. Schedule. The schedule for delivery of final drafts is as follows: February 28, 2006 Chapter 2 March 15, 2006 Chapter 3 March 31, 2006 Chapter 5 April 15, 2006 Chapter 1 April 30, 2006 Chapters 4, 7 May 15, 2006 Chapter 6 May 31, 2006 Chapter 8 (Index)

Introduction John opened the conference call. He said the purpose of the call is to review what we have to do before we meet in Albuquerque to go over the draft thoroughly. Contracts All the contracts are in place except for Craig Pon (Kinectrics) and Anands group. John will put that in place later this year or early next. Invoices John asked if there were any problems. He said it should take about two weeks to get paid. John asked Claude to tell him if he does not receive payment in a week. The fastest way to invoice is electronically. John will send an email to the whole team to identify the correct email address. John reminded the team to be sure to send final 2005 invoices by December 1, 2005.

A-17

Status of Chapters Jonas reviewed the status of chapters downloaded to the FTP site. Chapter 2 (Aeolian Vibration). One file is on the site. It looks very complete. Chapter 3 (Fatigue). Two files are thereone with text, the other with new figures. Jonas will insert the new figures into the text. Jonas requested a table of contents. Chapter 4 (Galloping). Fifteen files are on the site. Jonas will combine the sections and renumber the figures. He requested a table of contents. Chapter 5 (Bundle Conductors). Seven files are on the site. Jonas will combine the sections. Chapter 6 (Fiber Optic). One file and two case studies are on the site. Jonas requested a table of contents. Chapter 7 (Transient Motion). Jonas will include Anands outline. Spacer Dampers Claude asked where spacer dampers will be discussed. He said he assumed that they will be covered in Chapter 5, except as they concern Aeolian vibration. Giorgio said spacer dampers could be described in Chapter 5. However, he said the dynamics of the spacer would be covered in Chapter 2 on Aeolian vibration. Also some experiments related to Aeolian vibration would also be covered in Chapter 2. So Claude and Giorgio agreed that there is no disagreement about what each of their teams is covering. Chapters 1 and 8 Dave pointed out that the Progress Report should include at least a list of contents for those two chapters. Jonas said he would do this. Progress Report Jonas noted that he would include the current drafts of the chapters in the Progress Report. At this point he will NOT do any editing, other than to verify that the numbering of sections, figures, tables, and equations is correct. The Report will indicate that this version is a draft. Jonas will do this renumbering in the next week or so and re-post the files on the FTP site for review by the authors. If the authors wish to proceed with writing, they can use this latest version. If authors wish to make any changes for the draft included in this Progress Report, they should post a new file by November 1. Reviewers Giorgio asked who the reviewers will be. John said the first round will be internal review within the team itself. Users will review drafts after the Albuquerque meeting, once the drafts are more complete. Funders who review the Progress Report, once it is published in December, can also send comments to John. (This would be a preliminary user review.) Torsional Stiffness of Bundles Jean-Louis raised an issue concerning the torsional stiffness of bundles. He refers to it briefly in the galloping chapter, but he does not plan to cover it in that chapter. Is it appropriate in Chapter 5 or 7? Jeff and Claude agree that it should go in Chapter 7, but there can be references in Chapters 4 and 5.

A-18

Appendices Louis asked if lab test results should go in appendices within each chapter. John and Chuck said yes. Editing Jean-Louis asked if Jonas will take care of re-numbering of figures and introduce automatic numbering so that the authors can use it for future drafts. Jonas said he would prefer not to use automatic numbering, and that he will take responsibility for checking and re-doing numbering of figures, tables, etc. He said he would also take responsibility for putting references in the correct format to save authors time. Dave asked how many numbers are allowed in headings. Jonas said the maximum is three. After that, headings are boldface-italic and then just italic. But for now, it is acceptable to have different heading styles and numbering as long as it is consistent within the chapter. Charleston Meeting Several of the authors met on September 22 in Charleston. Topics discussed included: Author Bios. One topic discussed was the decision to use small author bios at the front of each chapter. Jonas will send a sample of the bios used in the Red Book. Bios and photos will be included of the key authors and co-authors. Referencing Format. Another topic was the new method of formatting references, which uses author and date, not numbers. Jonas said that he would make this change for authors if they did not want to take the time to do it. Surveys. It was suggested that there be a survey to users to obtain feedback on the plan for revision and the draft chapters. John and Jonas will develop a survey form to solicit specific responses, and this form will be included in the Progress Reportwith feedback on each chapter, on the format of the book, whats included and not included, and suggestions for applets. A boldface note could be included on the first page of the Progress Report to say that this is a draft only and that a survey form is included. Next Meeting The next meeting will be January 26-27, 2006 in Albuquerque, New Mexico, just after the IEEE meeting. These dates are confirmed so travel plans can be made. Dave has the hotel information and will send it to team members. Craig will send an email to John with the name of a person who can help John reserve a conference room. The meeting will be two full daysrunning until 5 pm on Friday. Craig will send an agenda of the IEEE meetings to all team members. John said the lead authors should just prepare a few slides on what has been done in each chapter, any coordination issues with other chapters, and any new theories or ideas that will be included in this edition.

A-19

Schedule Discussion was held to determine the deadlines for delivery of a complete (un-edited) draft of each chapter. Thorough review of the draft will take place at the Albuquerque meeting on January 26-27, 2006. The final draft will be re-submitted for user review by May 31, 2006. Final (electronic) publication is August 31. Chapters will be delivered to Jonas for editing on the following staggered schedule: February 28, 2006 Chapter 2 March 15, 2006 Chapter 3 March 31, 2006 Chapter 5 April 15, 2006 Chapter 1 April 30, 2006 Chapters 4, 7 May 15, 2006 Chapter 6 May 31, 2006 Chapter 8 (Index) After these dates, authors may add or revise, if necessary. After May 31, the chapters will be submitted for Editorial Committee review and user review. Conference calls will be held over the summer to discuss results of user review. Color Figures Jean-Louis asked if color figures would be allowed. Jonas said color would appear in the electronic version of the book, but that the hardcopy bound version would only be black-andwhite. Jonas will convert figures from color to black-and-white for authors. Copyright The issue of copyright permissions for borrowed material was raised. Jonas said that he would arrange for seeking copyright permissions.

RFP&Q 057308-01 BACKGROUND AND INSTRUCTIONS Introduction EPRI is sponsoring development of a new edition of the Transmission Line Reference Book: Wind-Induced Conductor Motion, commonly known as the Orange Book, which was originally published in 1979. This book covers the following topics: Aeolian Vibration Fatigue of Overhead Conductors Galloping Conductors Bundle Conductor Motions It is also planned to add material on Overhead Fiber Optic Cables and Transient and Other Motions. Development of a new edition is being undertaken for several reasons. First, while the book is still a well-used reference for conductor vibrations, it is now almost a quarter of a century old. Since its publication, there have been considerable developments in both approach and technology in this field. Second, there is also a concern that the book is too academic and cannot easily be put to practical uses. To address these concerns, revision of the book will update existing information in the Orange Book to reflect the state-of-the art knowledge in the field of wind-induced conductor motion. The revision process will also add new information to the book to cover topics, interests, and technology that have been developed since the book was last published. In addition, the revision will broaden the scope of the book to acquire global utility experience in conductor motion. As regards practicality, the audience for the book consists of transmission and distribution line designers and staff responsible for maintenance of overhead lines, interpretation of line failures, and correction of poor designs. The objective of this revision project is to provide them with the best practical tool to design overhead lines effectively in order to minimize damages to the lines from wind-induced conductor motion, and to analyze existing lines for improvements of their performance related to such motion. The new edition will include examples to facilitate the understanding of wind-induced conductor motion and the application of the knowledge to practical uses. Usability of the volume will be improved with inclusion of an index and other suitable electronic media. Overall, the goal will be to provide the electric power industry with a useful and practical reference guide that will complement the new edition of the Red Bookthe EPRI AC Transmission Line Reference Book: 200 kV and Above. Approach The strategy for the revision of the Orange Book is to assemble a group of world experts to update different chapters of the book or to write new chapters to cover advancements in technology in this field. These experts will be selected on the basis of the following RFP. In 2003, as part of the initial planning for the revision of the Orange Book, an Editorial Committee was formed to ensure that the book would be revised according to the projects goals. The Editorial Committee developed an initial revision plan for each chapter in the revised edition. These plans are captured in the skeleton outlines, which are included here as Attachments A and B, and described further below. The Editorial Committee also developed a list of possible interested participants, and outlined a production process for the book. The production process will be as follows: Once contracts have been awarded, lead authors will meet in May 2005 in Toronto to clarify objectives and review plans for revision. Authors and author-teams will write first drafts. There will be regular progress reports and conference calls, as frequently as progress merits. Drafts will be reviewed by the Editorial Committee, technical reviewers, and end-users. Initial drafts will be published in an EPRI report in October 2005. After drafts have been approved through technical review, chapters will be copyedited and laid out, and the book will be published. The production process is expected to last two years2005 and 2006. Bidders may participate in the revision of the book in several roles:

B-3

Lead Author/Manager. An expert will be selected to be the lead author/manager of each chapter. This author will have overall responsibility for the update or creation of that chapter, will be the single point-of-contact with the Editorial Committee, and will be accountable for deliverables. Lead authors will be required to attend the initial authors meeting. Lead authors heading up a team will be awarded a contract for the team. Bidders may bid to be the lead author of more than one chapter; however, a bidder will not be assigned to be the lead author of more than one chapter. Co-author. An expert may bid, and be selected, to write a portion of a chapter, and to participate with a team in developing a chapter. Resource Person. An expert may bid or volunteer to serve as an information resource for a team. This individual may suggest relevant references and approaches to material. Technical Reviewer. The Editorial Committee will hire technical experts to review each chapter for technical accuracy. In addition, authors may volunteer to review chapters other than their own. The draft will also be submitted for peer reviews by representative end-users.

Note: There will be an expert and/or team for each chapter. Forming a team among experts to complement one anothers skills is encouraged. Attachment C provides a list of interested participants with their contact information to enable bidders to solicit team members. Persons not on this list may also be contacted to participate as team members. The team is envisaged to include a lead author, coauthors, and resource people. Teams will be expected to cover all parts of a chapter. There is only one lead author/manager for each chapter. The Editorial Committee will assemble teams, where necessary. Scope of Work Bids are being accepted for revision of six chapters, as follows: Chapter 2: Aeolian Vibration Chapter 3: Fatigue of Overhead Conductors Chapter 4: Galloping conductors Chapter 5: Bundle Conductor Motions Chapter 6: Overhead Fiber Optic Cables Chapter 7: Transient and Other Motions Chapter 1 (Introduction) and Chapter 8 (Index, Glossary) will be developed by the Editorial Committee. The revision plan for the Orange Book is captured in a series of skeleton outlines. Attachment A is a summary version of these skeleton outlines. Attachment B is a more detailed version of the outlines. The outlines indicate proposals for: the scope of information to be included in each chapter, material from the previous edition that is to be reduced or moved, new areas of information to be added, possible examples, and references. Please consult these outlines before completing the Bidding Form. However, please note that these outlines are intended to be initial positions. Bidders are encouraged to indicate in the Bidding Form what they would do in addition to, or differently from, the proposed revision. Authors will also be responsible for suggesting the development of software applets to accompany the text. Applets are small, Java-based, stand-alone calculation modules. The applets provide users with sample problems and results to illustrate concepts in the text. The applets are interactive and allow users to input parameters and calculate results. Applets will be developed by programmers, but authors will need to work with the programmers to suggest areas of calculation and parameters. Chapters will be written according to an Authors Guide, which is included as Attachment E. For material from the current edition that is to be included unchanged in the revised edition, a Microsoft Word version of the first edition will be made available to authors. Note: Limited funding is available for this project. Cofunding will be a factor in the selection process. Cofunding may be in the form of unbilled hours, reduction in hourly rate, funding from other organizations, or support from other external sources.

INTRODUCTION

Aeolian vibration is one of the most important problems in transmission lines because it represents the major cause of fatigue failure of conductor strands or of items associated with the support, use, and protection of the conductor. In this phenomenon, conductor strand fatigue failures occur at the suspension clamps or at the clamps of the other devices installed on the conductor such as spacers, spacer dampers, dampers and other devices. Forces induced by vortex shedding are the cause of this type of vibration. From an aerodynamic and aeroelastic point of view, the problem is very complex as will be clearly explained in the following paragraphs. In addition, some differences arise in the mechanics of the phenomenon depending on whether single or bundled conductors are being considered. The response of the conductor to vortex shedding excitation is strongly non linear in terms of the vibration amplitude. This non-linearity is related to both the conductor parameters and the characteristics of the wind blowing across the conductor. From an engineering point of view, it is important to have a relatively simple approach to predict the conductor or bundle response to vortex shedding. The most common approach relies on the Energy Balance Principle (EBP) in which the steady state amplitude of vibration of the conductor or bundle due to aeolian vibration is that for which the energy dissipated by the conductor and other devices used for its support and protection equals the energy input from the wind. In this phenomenon, maximum vibration amplitudes can be as low as one conductor diameter where they can cause fatigue of the conductor strands due to bending. The problem may be defined as controlling the conductor vibration amplitude in order to maintain the stress in the conductor strands below the fatigue endurance limit. Adequate control can be achieved if the correct amount of damping is present in the system and if necessary, additional damping can be introduced in the form of damping devices such as dampers and space
