NATIONAL FOREWORD

This Indian Standard (Part 1) (Second Revision) which is identical to IEC 60831-1 : 2014 'Shunt power capacitors of the self-healing type for a.c. systems having a rated voltage up to and including 1 000 V - Part 1: General - Performance, testing and rating - Safety requirements - Guide for installation and operation' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Power Capacitors Sectional Committee and approval of the Electrotechnical Division Council.

This standard was first published in 1993 and revised in 2012. This revision has been undertaken to harmonize with the latest version of IEC 60831-1 : 2014.

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; and

e) The protection of the environment has been amended with safety concerns and plastic quality requirements.

The text of IEC standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and

b) Comma (,) has been used as a decimal marker, while in Indian Standards the current practice is to use a point (.) as the decimal marker.
