IEC？62271-1:2017 applies to AC switchgear and controlgear designed for indoor and/or outdoor installation and for operation at service frequencies up to and including 60？Hz and having rated voltages above 1？000？V.
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/IEC？directives,？Part？2 (2016) and IEEE Std.？C37.100.1.
4.1.2 a) The normal service condition for indoor switchgear is limited to one range of？40？°C to？-5？°C.
4.1.3 a) The normal service condition for outdoor switchgear is limited to one range of？40？°C to？-25？°C.
4.2.2:？The specifications from IEC？60071-2:1996 are adopted for altitude correction factors above？1？000 m.
5.2.2:？Range I, the rated voltage of？40,5？kV is added Series I Table？1; Table？2 and Table？4 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 IEC？60447.
7.2.6.1:Insert the wording regarding preliminary impulses across open vacuum interrupters according to the result of IEC？17/1026/RQ.
7.3:？Changed the requirement for radio interference voltage to a rated voltage level of 245？kV and above, instead of 123？kV 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, Table？14:
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 groups？1 and？2 of Table？14 according to IEC？TR？60943;
c. Expanded the definition of allowable temperature rise for categories of accessible surfaces with reference to IEC？Guide？117. See also Point？15 in 7.5.6.2.
7.5.6.2: Point？5 is modified to clarify the introduction of “OG” and “NOG” gas.
7.10:？Some tests were removed because the relevant test standards of IEC？60068 series were modified or withdrawn.
7.11.3:？The acceptance criteria for X-radiation testing are modified to recognize higher rated vacuum interrupters.
