NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with IEC 61954 (2013) ‘Static var compensators (SVC) - Testing of thyristor valves’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the HVDC Power Systems Sectional Committee and approval of the Electrotechnical Division Council.

This standard was first published in 2005 in dual number identical to IEC 61954 : 2003. This revision has been undertaken to keep pace with the revision of corresponding IEC standard.

The text of IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminology 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’.

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.
