SHUNT CAPACITORS FOR AC POWER SYSTEMS
HAVING A RATED VOLTAGE ABOVE 1 000 V –
Part 2: Endurance testing
AMENDMENT 1
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

Amendment 1 to IEC TS 60871-2:2014 has been prepared by IEC technical committee 33:

Add, after Clause 4, the following new text:
5 Element fail safe test for fuseless capacitors
5.1 General

The proof of element fail safe is a design test applicable to fuseless power capacitors, as

defined in IEC 60871-1:2014, Clause E.4.

This proof is obtained by means of two separate tests, the low energy test and the high energy

test.

The low energy test is aimed to demonstrate that a failure of one capacitive element, caused

by a low voltage element failure event at the rated voltage, will result in reliable and secure foil

welding on the failed portion of the element without generation of hot spots and persistent

release of gas.

The high energy test is aimed to demonstrate that a failure of one or more capacitive elements,

caused by the occurrence of an overvoltage on the capacitor bank, will result in reliable and

safe behaviour without container rupture or explosion.

The physical location of the fault on the capacitor element is intended to represent the worst

possible location under the expected low or high energy level tested. A damage to the insulation

of the container is acceptable, provided that it maintains enough insulation in order to remain

in service until replacement.
5.2 Test unit
5.2.1 General

Two set-ups of the test unit are possible, as described in 5.2.2 and 5.2.3; the manufacturer

shall choose the set-up and manufacture the test unit accordingly.
5.2.2 Set-up of the test unit, first method

The test unit shall be a capacitor unit comparable to the units to be manufactured, as described

in Annex A, with the following features:

• The container shall be identical to that used for the units to be manufactured.

• The test unit shall contain a single active element, i.e. electrically connected to the bushings

for power supply; the other elements shall be passive, i.e. not electrically connected neither

to the active element nor to the bushings.
• The unit may be equipped
