BUREAU OF INDIAN STANDARDS DRAFT FOR COMMENTS ONLY Draft Indian Standard Doc: ETD 08 (11701) (IS/IEC 62271 104 : 2015) High-voltage switchgear and controlgear - Part 104: Alternating Current Switches for rated voltages higher than 52 kv (first revision) This document was earlier issued in wide circulation on 07 th July 2017. During the 24 th Meeting of High Voltage Switchgear and Controlgear Sectional Committee, ETD 08, it was decided to re-issue the document in wide circulation for a period of 15 days. Accordingly, the document is being circulated again. Last date for receipt of comments is : 24 January 2019 High Voltage Switchgear and Controlgear Sectional Committee, ETD 08 NATIONAL FOREWORD This draft Indian Standard (Part 104) which is identical with IEC 62271-104 : 2015 High-voltage switchgear and controlgear Part 104 Alternating Current Switches for rated voltages higher than 52 kv issued by the International Electrotechnical Commission (IEC) may be adopted by the Bureau of Indian Standards on the recommendation of the High Voltage Switchgear and Controlgear Sectional Committee and approval of the Electrotechnical Division Council. This standard was first published in 2015 and was identical with IEC 62271-104 : 2009. This IEC standard has since been revised as IEC 62271-104:2015. The revision of this standard (Part 104) has been taken up to incorporate the technical modifications and align it with latest IEC standard. The revised draft standard includes the following significant technical changes with respect to the previous version: the title was changed such that the voltage range now is > 52 kv instead of 52 kv; the references have been updated; This standard should be read in conjunction with IS/IEC 62271-1:2007, to which it refers and which is applicable unless otherwise specified. In order to simplify the indication of corresponding requirements, the same numbering of clauses and subclauses is used as in IS/IEC 62271-1. Amendments to these clauses and subclauses are given under the same numbering, whilst additional subclauses, are numbered from 101. The text of IEC Standard may be 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 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 draft adopted standard, reference appears to certain International Standards for which Indian Standards also exist. The corresponding Indian Standards, which may be substituted in their places, are listed below along with their degree of equivalence for the editions indicated: International Standard Corresponding Indian Standard Degree of Equivalence IEC 60050-441:1984 International Electrotechnical Vocabulary Chapter 441: Switchgear, controlgear and fuses IS 1885 (Part 17) : 1979 Electrotechnical vocabulary: Part 17 Switchgear and controlgear (first revision) Technically equivalent to IEC 60050-441 : 1974 IEC 60071-1 : 2006 Insulation coordination Part 1: Definitions, principles and rules IEC 60270 : 2000 High-voltage test techniques Partial discharge measurements IEC 62271-1 : 2007 High-voltage switchgear and controlgear Part 1: Common specifications Amendment 1 (2011) IS 2165 (Part 1) : 1977 Insulation co-ordination : Part 1 Phase to earth insulation co-ordination principles and rules (second revision) IS/IEC 60270 : 2000 High-voltage test techniques Partial discharge measurements IS/IEC 62271 (Part 1 ): 2007 High voltage switchgear and controlgear standards Part 1: Common specification Technically equivalent to IEC 60071-1 : 1976 Identical Identical with IEC 62271-1 : 2007 IEC 62271-100 : 2008 High-voltage switchgear and controlgear Part 100: Alternating-current circuit-breakers Amendment 1 (2012) IS/IEC 62271-100 : 2008 Highvoltage switchgear and controlgear: Part 100 Alternating-current circuit-breakers Identical with IEC 62271-100 : 2008 IEC 62271-102 : 2001 High-voltage switchgear and controlgear Part 102: Alternating current disconnectors and earthing switches Amendment 1 (2011) Amendment 2 (2013) IS/IEC 62271-102 : 2003 Highvoltage switchgear and controlgear: Part 102 Alternating current disconnectors and earthing switches Identical with IEC 62271-102 : 2001 The technical committee responsible for preparation of this draft standard would review the provisions of the following International standards referred in this draft standard and would decide whether they are acceptable for use in conjunction of this standard: International Standard IEC 60071 (all parts) IEC 62271-110 : 2012 Insulation co-ordination Title High-voltage switchgear and controlgear Part 110: Inductive load switching
