Unreliability Demonstration Procedure

7. General

Since there are only a few Mobile Substations according to Annexure C in this tender, it is

not practical to apply a standard – classic reliability demonstration plan (i.e. IEC-60605, or

IEC-61124). This fact is due to the long calendar test time expected in such a

demonstration. For this reason an “unreliability demonstration” was designed for this

tender, and I.E.C will prepare a UDP, based on the following principals.

In the UDP the UPPER limit for the MTBF, rather than the lower limit, will be calculated

from demonstration results, with given confidence level. Thus, this test will verify if the

demonstrated MTBF is WORSE than a certain value (close to the required MTBF).

The purchased MOBILE SUBSTATION will be participating in an Unreliability

Demonstration Procedure (UDP) after their installation, in order to verify in case they do

not comply with their specified reliability (Failure Rate/MTBF). The UDP will be started

right after the installation, and operation of the MOBILE SUBSTATION, and will be

performed by I.E.C crew. Final parameters for the UDP will be discussed at contract

phase.

7.1 Reliability Requirements

The maximum acceptable failures rate, or minimum MTBFs are as follows:

(1) 0.01/Yr for Major failures (MTBF, = 100 Yrs).

(2) 0/04/Yr for Minor failures (MTBF, = 25 Yrs).

7.2 Plan Parameters

(1)Test Time

The Test Time is the operating time summation of all tested units. It is measured in

Units*Years and depended on agreed contractor risks. In the further it was calculated for

contractor risks only. The more of units the less of years (calendar time) since the Test

Time it is fixed. In case of a failure, the faulty MOBILE SUBSTATION will be repaired and

replaced as soon as possible otherwise; the calendar time will be lengthening, to keep

Test Time to agreed Units*Years demonstration.


App B2/9

(2) Maximum Number of Failures

Using equations: (1), and (2) in the following Par. 7.3, the maximum number of failures

allowable is determined to be as follows:

- 1 minor failure.

- 0 (zero) major failures.

Description Minor Failures Major Failures

Test Time*Units [Unit*Years] Ta=15 Ta=15

calendar time of test [years] t=1.5 t=1.5

Reject if faults number are r = 2 1

Probability of rejection 0.122 0.139

U [Yrs] with CL=80% 28 142

Where:

r - Number of relevant failures.

- Contractor’s risk.

U - Upper limit for the MTBF

CL - Confidence level

7.3 Rational

If the number of occurring failures in t years is X, and the maximum failures allowed in that

period is k, then the probability of not passing the demonstration is, when there will be

more than k failures in t years. The probability is actually identical to Contractor’s risk ().

This risk is given by the following Poisson distribution formula:

k

App B2/10

7.4 Failure Policy and Consideration

(1) I.E.C will implement a Failure Reporting, and Analysis System.

(2) All kinds of failures will be registered by the Failure Detector, in a Failure Report Form

(FRF) including those occurring during the Warranty Period. However, only the

relevant ones will be considered and counted for Accept/Reject criterion. The FRF will

include all failure information.

(3) In case of Systematic Failure the manufacturer will repair all the MOBILE

SUBSTATION, and perform a Corrective Action (preventive measures) to all the

MOBILE SUBSTATION including which already installed, to I.E.C satisfaction. In this

case, the Failure Review Board (as detailed in aragraph 7.5) may decide, depends

upon the failure severity, to reset the accumulated test time, and to restart the RFD

from the beginning,

(4) In all other failures (Minor or Major failures) the time test measurement will be

resumed after the repair.

(5) Parts replacement due to and during preventive maintenance action will not be

considered as a failure.

7.5 Failure Review Board

The FRF will be presented to a Failure Review Board (FRB) for reviewing, discussing and

deciding. The FRB will be headed by an I.E.Co engineer, and composed of I.E.Co and

Contractor members. Only the FRB is entitled to decide any decision about a failure

(classification, repair, corrective action, etc.) after failure analysis and investigation. The

conclusions of the FRB discussion will be registered in a Reliability Demonstration

Logbook (RDL).

7.6 Penalties

(1) After and only after expiration of the Warranty Period even in the course of the UPD,

I.E.Co. will assume full responsibility for all repair/replace costs. Anyway, during

Warranty Period the Contractor will assume full responsibility for all repair/replace

costs.

(2) If the UDP is terminated in “Accept” decision, responsibility remains as stated in the

previous paragraph (para. 1).


App B2/11

(3) If the UDP is terminated in “Reject” decision due to Major Failures, The Contractor will

retroactively assume responsibility for all repair/replace cost and will extend his

Warranty for Major Failures only to additional period of ten (10) years.

(4) If the UDP is terminated in “Reject” decision due to Minor Failures, The Contractor will

retroactively assume responsibility for all repair/replace cost and will extend his

Warranty for Minor Failures only to additional period of ten (10) years.

8. Terms and Definitions

(1) Failure

A failure is any event where a MOBILE SUBSTATION stops functioning, or functions

outside of its specification limits, and requires a repair/replacement. The failures can

be divided into two groups, Relevant and Non-relevant failures.

(2) Non Relevant Failure

A Non Relevant Failure is a failure that was caused by one of the following events:

Incorrect installation, or not in accordance with Contractor’s instruction.

Misuse, or not in accordance with Contractor’s instruction.

Caused by test equipment.

External cause, “Force Major” etc. (i.e. lightning).

Secondary Failure.

(3) Relevant Failure

A Relevant Failure is a failure that could happen in real life, and was not defined as

“Non Relevant”. Also, a Relevant Failure is a failure that causes a MOBILE

SUBSTATION malfunction or undesirable operation (Including repair/replace, and

logistic times).

(4) Systematic Failure

A Systematic Failure is a Relevant Failure that happens two times or more, and

therefore it required a Corrective Action. A systematic failure can be eliminated only by

a modification of the design, manufacturing process, or operational procedures. A

systematic failure can be induced at will by simulating the failure cause, and it is called

also Reproducible Failure (Systematic Failures group is sub group contained in

Relevant Failures group).

(5) Random Failure

A Random Failure is a failure that its root cause is of a “random nature”, and cannot be

defined as “Systematic Failure”.


App B2/12

(6)Major Failure

A “Major Failure” is a failure that causes a forced MOBILE SUBSTATION stop

functioning.

(7)Minor Failure

A “Minor Failure” is a failure that causes a MOBILE SUBSTATION functions outside of

its specification and may generate undesirable action (Including repair/replace, and

logistic times).

(8) Secondary Failure

A “Secondary Failure” is a failure that was caused by another failure.

(9) Test Time

“Test Time” is the cumulative summation of operating time of all MOBILE

SUBSTATION participating in this demonstration.

(10)Failure Review Board

A Failure Review Board (FRB) is the body entitled to decide about failure matters. The

main task of the FRB is to analyze the failures, and especially to decide as to failure

classification, and Corrective Actions. The FRB made up from Contractor and I.E.Co.

representatives.

(11)Failure Rate

The failure rate, of a MOBILE SUBSTATION is the number of failures per operating

time unit.

(12)MTBF

MTBF is the mean operating time between failures of a MOBILE SUBSTATION. MTBF

= 1/.

Reliability

Reliability is a design characteristic defining the ability of a MOBILE SUBSTATION to

perform satisfactorily. Therefore, the MOBILE SUBSTATION reliability is the probability

that the MOBILE SUBSTATION will perform without failures, for a pre-defined period of

time, when used under stated conditions (in I.E.Co.’s customer site). MTBF is a

reliability parameter.

(13)Life Length

The life length of a MOBILE SUBSTATION is the time until the accumulated repair cost

sum up to the half of the price of a new one.

(14) Maintenance


App B2/13

Maintenance is any action taken by technical staff to:

Restore a faulty item to its operable condition after a failure, or:

Preserve the operable, or safety condition of a good item, or:

Test the operable condition of an item.

(15)Preventive Maintenance

Preventive Maintenance (PM) is the maintenance actions carried out on a good unit, at

predetermined intervals, or in accordance with prescribed criteria, and intended to

reduce the MOBILE SUBSTATION probability of a future failure, or degradation of the

functioning of the item.

(16)MTTR

MTTR is the mean time required to perform a repair (including checks) or replace of a

MOBILE SUBSTATION.

(17)Maintainability

Maintainability is a design characteristic defining the ability of a MOBILE SUBSTATION

to be restored quickly to its operable condition after a failure. Therefore, a MOBILE

SUBSTATION maintainability is the probability that a failed MOBILE SUBSTATION is

restored to its functioning condition, within specified period of time, under stated

condition, using stated procedures (defined by the Contractor), and resources (defined

by the I.E.Co.). MTTR is a maintainability parameter.

CONTRACTOR’S TECHNICAL PERFORMANCE GUARANTEES

When during testing it is shown that the losses exceed the guaranteed level plus

tolerances on the principal, minimum and maximum taps as stated in this

Specification, the Contractor shall pay the I.E.Co. liquidated damages as follows:

1. For each transformer unit that the losses exceed the guaranteed level plus

tolerances on the principal, minimum and maximum taps, the Contractor shall

pay for each kW of losses in excess of the declared values (subcl. 10.3.21.4)

, without tolerances, liquidated damages as prescribed hereunder:

1.1. No-load losses - US$ 6050

1.2. Short-circuit losses - US$ 1850

1.3. Auxiliary power - US$ 2800

The liquidated damages are a genuine estimate of the direct damages foreseen

and are not to be regarded as penalty. They shall be calculated separately for

each type of losses indicated above and shall be cumulative.

2. For each type of transformer delivered according to this Specification the

average tolerances of no-load and short-circuit losses shall not exceed zero.

For each one percent which the average tolerance exceeds the guaranteed

value the Contractor will pay the I.E.Co. a compensation of one percent of the

Contract value.

The reference temperature for the losses considered in the calculation of the

above indicated damages shall be the standard reference temperature.

The calculation of exceeded losses will be performed separately for each type of

transformer and separately for no-load and short-circuit losses as well as for the

losses on the principal, minimum and maximum transformer taps.

PROCEDURE

FOR

HANDLING OF NON-CONFORMANCES


App B10/2

It is the obligation of the Contactor to inform Israel Electric Corp. Ltd. (I.E.Co.) about

any deviation from the contract technical specifications, which occurs on any

action/item of the contract realization, such as design, raw materials, manufacturing

testing and inspection and so on. The deviations will be classified into the following

three (3) non conformance levels:

1. NON CONFORMANCE LEVELS

1.1. Non conformance (NC) of Level 1:

1.1.1. NC which do not affect the compliance to the contract technical specifications and the contract value.

1.1.2. NC which leads to slight modification into the contract technical specifications, but has certainly no effects on performance, neither on the short term nor on the long term, as well as not on the contract value.

1.2. Non-conformance of Level 2:

1.2.1. NC which do not affect the contract value but leads to modification of one or more the contract technical specifications, which has slight effects on secondary performances.

1.2.2. Scrapping parts with influence on the delivery time.

1.3. Non-conformance of Level 3:

1.3.1. Any other NC which is not included in the previous levels (For instance such a NC which can affect even uncertainly mandatory requirement or contract value).


App B10/3

HANDLING OF NON CONFORMANCE

Contractor reporting duty according to each non conformance levels below:

1.4. Level 1: No duty of notification.

1.5. Level 2: Duty of notification.

Within one (1) week the Non Conformity Report will be delivered to I.E.Co. Project Manager.

A Corrective Action (CA) Report is required, including the influence on time schedule, or other relevant contract issue, if any.

I.E.Co. has the right to send their remarks to the reports, including discuss the NC level classification.

1.6. Level 3: Duty of notification and approval by IECo necessary.

1. The Contactor shall stop the manufacturing immediately.

2. The Contactor will deliver a NC Report to I.E.Co. Project Manager within one (1) week.

3. When the disposition is to repair a detailed repair procedure must be presented to I.E.Co for approval immediately upon its issuing including a CA.

4. I.E.Co. will send its approval or rejection for the disposition within one (1) week. Any and only supplementary day will not be accounted as contactor delay.

5. Only after I.E.Co.’s approval the Contractor can resume manufacturing.

6. The NC equipment may be rejected in case of unsuitable implementation of the repair procedure and/or the CA taken.

7. Successful completion of the repair procedure and the CA should be reported to I.E.Co.

APPENDIX D2

Time Synchronization

AUGUST 2016


App D2/2

1. TIME-SYNCHRONIZATION

1.1. General description

IEC's (Israel electric company) specifications for digital relays and digital

systems for substations include requirements for time-synchronization, by a

GPS system, located in the substation.

Two methods of time-synchronization for digital relays and digital systems are

possible (see Drawing TS-1):

1. Direct synchronization link between a digital relay or system and a

GPS system in the substation.

2. Time synchronization of digital relays and systems through the LAN

(Local Area Network) of the central control system of the substation.

1.2. General requirements

For both methods, the IEC had made a set of the following minimum

requirements:

1. The time resolution in the log (event/fault recorder) of the time-

synchronized relays/systems will be 1 (one) millisecond or a fraction of a

millisecond.

2. The time difference between the log of time-synchronized digital

relays/systems in a given substation (∆T1), will not be more than 5 (five)

millisecond.

3. The time difference between the log of digital relays which comprise one

organic system (e.g. decentralized fault-recorder, protection or control

system) (∆T2), will not be more than 1 (one) millisecond (see Drawing TS-

2).

4. The time difference between the log of a REFERENCE GPS system, and

the log of each of the time-synchronized digital relays/systems in the

substation (∆T3), will not be more than 10 (ten) millisecond (see Drawing

TS-3).


App D2/3

1.3. Method of testing

(Drawing TS-3).

A GPS system with an internal log and a discrete input will serve as a

REFERENCE GPS.

One pulse at a time will be sent to a discrete input of each of the tested relays
