IS 12729:2004IEC 60694(2002)High-Voltage Switchgear and Controlgear Sectional Committee, ET 08NATIONAL FOREWORDThis Indian Standard (First Revision) which is identical with IEC 60694 (2002) ‘Common specificationsfor high-voltage switchgear and controlgear standards’ issued by the International EiectrotechnicalCommission (lEC) was adopted by the Bureau of Indian Standards on the recommendations of theHigh-Voltage Switchgear and Controlgear Sectional Committee and approval of the ElectrotechnicalDivision Council.The text of IEC Standard has been approved as suitable for publication as an Indian Standard withoutdeviations. 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 beread as ‘Indian Standard’; andb)Comma (,) has been used as a decimal marker while in Indian Standards, the current practiceis to use a point (.) as the decimal marker.Amendment No. 1 and 2 issued by IEC in 2000 and 2001 have been incorporated.Only the English text in the IEC Publication has been retained while adopting it in this IndianStandard, and as such the page numbers have been given afresh here since they are not the sameas in tEC Publication.CROSS REFERENCESIn this adopted Standard, reference appears to certain International Standards for which IndianStandards also exist. The corresponding tnd”km Standards which are to be substituted in theirrespective places are listed below along with their degree of equivalence for the editions indicated:/nternationa/StandardCorrespondingDegree ofEquivalenceIndian StandardIEC 60034-1 (1996) Rotating electricalmachines — Part 1 : Rating andperformanceI-S 7132: 1973 Guidesynchronous machinesfortestingIEC 60050-131(1 978)InternationalElectrotechnical Vocabulary(IEV) —Chapter 131 Electric and magneticcircuitsIS 1885 (Part 57) : 1993 Electrotechnicalvocabulary: Part 57 Electric and magneticcircuits (first revision)IdenticalIEC 60050-151(1978)InternationalElectrotechnical Vocabulary(IEV) —Chapter 151 Electrical and magneticdevicesIS 1885 (Part 74) : 1993 Electrotechnicalvocabulary: Part 74 Electric and magneticdevicesdoIEC -60050-301(1983)InternatiorwdElectrotechnical Vocabulary(1EV) —Chapter301Generaltermsonmeasurements in electricityIS 1885 (Part 80) : 1994 Electrotechnicalvocabulary: Part 80 General terms onmeasurements in electricitydoIEC 60050-351(4998)InternationalElectrotechnical Vocabulary(IEV) —Chapter 351 Automatic controlIS 1885 (Part 75) : 1993 Electrotechnicalvocabulary: Part 75 Automatic controlTechnicallyequivalentTechnicallyequivalent
