IS 16071 : Part 1 : 2024/IEC/TR 62001-1 : 2021 High-Voltage Direct-Current (HVDC) Systems - Guidance to the Specification and Design Evaluation of a.c. Filters - Part 1 Overview
(Superseding IS 16071 : 2013)
NATIONAL FOREWORD
This Indian Standard (Part 1) (Second Revision) which is identical to IEC TR 62001-1 : 2021 'Highvoltage direct current (HVDC) systems - Guidance to the specification and design evaluation of a.c. filters - Part 1: Overview' 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.
This standard was first published in 2013 as IS 16071 : 2013 was identical to IEC/TR 62001 : 2003 and was revised in 2021 as IS 16071 (Part 1) : 2021 was identical to IEC TR 62001-1 : 2016. 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 62001-1 : 2021.
This Indian Standard is published in four parts. The other parts of this series are given below:
Part 2 Performance
Part 3 Modelling
Part 4 Equipment
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.
