IS 17575 : 2024/IEC/TR 62681 : 2022 Electromagnetic Performance of High-Voltage Direct-Current (HVDC) Overhead Transmission Lines
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to IEC TR 62681 : 2022 'Electromagnetic performance of high voltage direct current (HVDC) overhead transmission lines' 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 standard was first published in 2021 and was identical to IEC TR 62681 : 2014. This revision has been undertaken to take into consideration the developments that have taken place subsequently and also to align the standard with the latest version of IEC TR 62681 : 2022.
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.
