IS 8792 : 2023/IEC 60353 : 1989 Line Traps for a.c. Power Systems
NATIONAL FOREWORD
This Indian Standard (Second Revision) which is Identical to IEC 60353 : 1989 'Line traps for a.c. power systems' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendations of the Power system control and associated communication sectional committee and approval of the Electronics and Information Technology Division Council.
This Indian Standard was originally published in 1978 and was largely based on IEC 60353 : 1971. The first revision of this standard was published in 1995 and was largely aligned with IEC Publication 353- 1989 (Second Edition) Line Traps for a.c. Power Systems. The second revision of this standard aligns this Indian Standard with IEC 60353 :1989 along with amendment 1 Published in 2002.
Amendment 1 : 2002 is attached at the end of this document.
The text of IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are however not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appears 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.
