IS 18597 : Part 3 : 2024/IEC 60700-3 : 2022 Thyristor Valves for High-Voltage Direct-Current (HVDC) Power Transmission - Part 3 Essential Rating (Limiting Values) and Characteristics

NATIONAL FOREWORD

This Indian Standard (Part 3) which is identical to IEC 60700-3 : 2022 'Thyristor valves for high voltage direct current (HVDC) power transmission - Part 3: Essential ratings (limiting values) and characteristics' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the HVDC Power Systems Sectional Committee 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 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.
