IS 2165 : Part 5 : 2005 /IEC 60071-5 : 2002 Insulation Co-Ordination - Part 5 : Procedures for High-Voltage Direct Current (HVDC) Converter Stations

National Foreword

This Indian Standard which is identical with IEC 60071-5 : 2002 ?Insulation co-ordination - Part 5: Procedures for high-voltage direct current ( HVDC ) converter stations? issued by the International Electrotechnical Commission ( IEC ) was adopted by the Bureau of Indian Standards on the recommendations of the HVDC Power Systems Sectional Committee ( ET 40 ) and approval of the Electrotechnical Division Council.

The text of the 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.

In this adopted standard, reference appears to certain International Standards for which Indian Standards also exist. The corresponding Indian Standards which are to be substituted in their respective places are listed below along with their degree of equivalence for the editions indicated:
