FOREWORD
The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
1)
comprising all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards.
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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the
form of standards, technical reports or guides and they are accepted by the National Committees in that
sense.
In order to promote international unification, IEC National Committees undertake to apply IEC International
4)
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the
subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 831-1 has been prepared by IEC technical committee 33:
Power capacitors.
This second edition cancels and replaces the first edition published in 1988, its amend-
ment 1 (1991), and amendment 2 (1993), and constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
33/234/FDIS
33/249/RVD
33/234A/FDIS
Full information on the voting for the approval of this standard can be found in the report
on voting indicated in the above table.
Annexe A forms an integral part of this standard.
Annexe B is for information only.

–
(IEC 871).
Capacitors for inductive heat-generating plants operating at frequencies between
–
40 Hz and 24 000 Hz (IEC 110).

– Coupling capacitors and capacitor dividers (IEC 358).
– Capacitors to be used in power electronic circuits (IEC 1071).
Small a.c. capacitors to be used for fluorescent and discharge lamps (IEC 1048 and
–
IEC 1049).
– 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.
831-1 © IEC:1996 - 11 -
The object of this part of IEC 831 is to:
a) formulate uniform rules regarding performances, testing and rating;
formulate specific safety rules;
b)
c) provide a guide for installation and operation.
