IEC62271-1:2017 applies to AC switchgear and controlgear designed for indoor and/or outdoor installation and for operation at service frequencies up to and including 60Hz and having rated voltages above 1000V.This document applies to all high-voltage switchgear and controlgear except as otherwise specified in the relevant IEC standards for the particular type of switchgear and controlgear.This second edition cancels and replaces the first edition published in 2007 and Amendment 1:2011. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:New numbering in accordance with ISO/IECdirectives,Part2 (2016) and IEEE Std.C37.100.1.4.1.2 a) The normal service condition for indoor switchgear is limited to one range of40°C to-5°C.4.1.3 a) The normal service condition for outdoor switchgear is limited to one range of40°C to-25°C.4.2.2: The specifications from IEC60071-2:1996 are adopted for altitude correction factors above1000 m.5.2.2: Range I, the rated voltage of40,5kV is added Series I Table1; Table2 and Table4 are updated on recommendation of the US National Committee.6.8: New subclause added for manual operated actuators consistent with “Man Machine Interface” recommendations of IEC60447 .7.2.6.1:Insert the wording regarding preliminary impulses across open vacuum interrupters according to the result of IEC17/1026/RQ.7.3: Changed the requirement for radio interference voltage to a rated voltage level of 245kV and above, instead of 123kV and above. This change is based on reported positive test and service experience of utility representatives in the maintenance team of this standard.7.5.6, Table14:a. Introduced the distinction of parts in “OG” (oxidizing gas) or in “NOG” (not oxidizing gas) replacing the former “air” and “SF6”;b. Increased the allowable temperature rise for some parts in groups1 and2 of Table14 according to IECTR60943;c. Expanded the definition of allowable temperature rise for categories of accessible surfaces with reference to IECGuide117. See also Point15 in 7.5.6.2.7.5.6.2: Point5 is modified to clarify the introduction of “OG” and “NOG” gas.7.10: Some tests were removed because the relevant test standards of IEC60068 series were modified or withdrawn.7.11.3: The acceptance criteria for X-radiation testing are modified to recognize higher rated vacuum interrupters.Former informative AnnexH: Corrosion is deleted, the content is part ofIECTR62271-306.New AnnexJ(informative): Added informative guidelines for the extension of validity of type testsNew AnnexK(informative): Added informative guidelines about exposure to pollution
