Overview

EN 60831-2:2014 (IEC 60831-2:2014) specifies the ageing test, self‑healing test and destruction test for shunt power capacitors of the self‑healing type intended for a.c. systems with a rated voltage up to and including 1 000 V. Published by CLC/CENELEC as the European adoption of IEC 60831-2 (third edition), this part complements IEC 60831-1 (general performance, testing, rating and safety). The 2014 edition is a technical revision that updates normative references and introduces important changes to test procedures and acceptance criteria.

Key topics and technical requirements

• Scope and linkage: Applies to capacitors manufactured and assessed under IEC 60831-1; defines detailed test requirements for durability and safety.
• Ageing test: Conditioning and three‑part test sequence including long‑term energization at elevated voltage, discharge cycles and final verification. Test setups may use forced‑air circulation or a liquid bath to maintain case temperature; capacitance is measured before testing.
• Discharge cycles: The standard requires controlled discharge cycling (updated so some discharge cycles before ageing may be at ambient temperature). Discharge circuits use an inductance sized according to the measured capacitance (see standard for the formula and permissible tolerances).
• Self‑healing test: Procedures to verify the capacitor’s ability to isolate and recover from dielectric breakdowns. The 2014 edition adds an alternative self‑healing test at d.c. voltage and revises acceptance conditions after self‑healing.
• Destruction test: Defines sequence and pass/fail criteria for end‑of‑life/destruction testing; the 2014 version includes modifications to these test requirements and the associated circuit arrangements.
• Test equipment and annexes: Annex A gives informative examples of self‑healing breakdown detection equipment and practical circuit arrangements for testing.

Applications and users

• Manufacturers of self‑healing shunt power capacitors use EN 60831-2 for type testing, R&D validation and quality control.
• Independent test laboratories and certification bodies apply these procedures when issuing conformity or safety reports.
• Specifiers, procurement and utilities reference the standard to ensure components meet durability, safety and self‑healing performance requirements for low‑voltage a.c. systems (≤ 1 000 V).
• Design and safety engineers use the standard to define acceptance criteria, verify lifetime behaviour and assess failure modes for capacitor banks.

Related standards

• IEC 60831-1 / EN 60831-1 – General requirements, performance, testing and guide for installation and operation (normative reference).
• Other parts of the IEC 60831 series covering additional aspects of shunt power capacitors.

Keywords: EN 60831-2:2014, IEC 60831-2, IEC 60831-1, ageing test, self‑healing test, destruction test, shunt power capacitors, rated voltage 1000 V.

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 60831-2 has been prepared by IEC technical committee 33: Power
capacitors and their applications.
This third edition cancels and replaces the second edition published in 1995. 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) Discharge cycles before ageing test carried out at ambient temperature;
c) Alternative Self-healing test at d.c. voltage;
d) Modified acceptance conditions after Self-healing test;
e) Modifications to Destruction test.
