Shunt power capacitors of the self-healing type for a.c. systems having a rated voltage up to and including 1000 V - Part 1: General - Performance, testing and rating - Safety requirements - Guide for installation and operation

This part of the IEC 60831 series is applicable to both capacitor units and capacitor banks
intended to be used, particularly, for power-factor correction of a.c. power systems having a
rated voltage up to and including 1 000 V and frequencies of 15 Hz to 60 Hz.
This part of IEC 60831 also applies to capacitors intended for use in power filter circuits.
Additional definitions, requirements, and tests for power filter capacitors are given in Annex A.
The following capacitors are excluded from this part of IEC 60831:
– Shunt power capacitors of the non-self-healing type for a.c. systems having a rated
voltage up to and including 1 000 V (IEC 60931-, -2 and -3).
– Shunt capacitors for a.c. power systems having a rated voltage above 1 000 V
(IEC 60871-1, -2, -3 and -4).

IEC 61049).
– Capacitors for suppression of radio interference (under consideration).
– Capacitors intended to be used in various types of electrical equipment, and thus
considered as components.
– Capacitors intended for use with d.c. voltage superimposed on the a.c. voltage.
Accessories such as insulators, switches, instrument transformers, fuses, etc., should be in
accordance with the relevant IEC standards and are not covered by the scope of this part of
IEC 60831.
The object of this part of IEC 60831 is to:
a) formulate uniform rules regarding performances, testing and rating;
b) formulate specific safety rules;
c) provide a guide for installation and operation.

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.
International Standard IEC 60831-1 has been prepared by IEC technical committee 33: Power
capacitors and their applications.
This third edition cancels and replaces the second edition published in 1996 and Amendment
1:2002. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Updating of the normative references;
b) Test conditions have been clarified;
c) Thermal stability test has been clarified;
d) Maximum permissible voltage and current have been clarified;

e) The protection of the environment has been amended with safety concerns and plastic
quality requirements.
The text of this standard is based on the following documents:
FDIS Report on voting
33/543/FDIS 33/550/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60831 series, published under the general title Shunt power
capacitors of the self-healing type for a.c. systems having a rated voltage up to and including,
1 000 V can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
The contents of the corrigendum of May 2014 have been included in this copy.

rated voltage up to and including 1 000 V and frequencies of 15 Hz to 60 Hz.
This part of IEC 60831 also applies to capacitors intended for use in power filter circuits.
Additional definitions, requirements, and tests for power filter capacitors are given in Annex A.
The following capacitors are excluded from this part of IEC 60831:
– Shunt power capacitors of the non-self-healing type for a.c. systems having a rated
voltage up to and including 1 000 V (IEC 60931-, -2 and -3).
– Shunt capacitors for a.c. power systems having a rated voltage above 1 000 V
(IEC 60871-1, -2, -3 and -4).
– Capacitors for inductive heat-generating plants operating at frequencies between 40 Hz
and 24 000 Hz (IEC 60110-1 and -2)
– Series capacitors (IEC60143-1, -2, -3 and -4)
– AC motor capacitors (IEC 60252-1 and -2)
– Coupling capacitors and capacitor dividers (IEC 60358-1)
– Capacitors for power electronic circuits (IEC 61071).
– Small a.c. capacitors to be used for fluorescent and discharge lamps (IEC 61048 and
IEC 61049).
– Capacitors for suppression of radio interference (under consideration).
– Capacitors intended to be used in various types of electrical equipment, and thus
considered as components.
– Capacitors intended for use with d.c. voltage superimposed on the a.c. voltage.
Accessories such as insulators, switches, instrument transformers, fuses, etc., should be in
accordance with the relevant IEC standards and are not covered by the scope of this part of
IEC 60831.
The object of this part of IEC 60831 is to:
a) formulate uniform rules regarding performances, testing and rating;
b) formulate specific safety rules;
c) provide a guide for installation and operation.
