規格概要
IEC TR 62271-307:2024 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC TR 62271-307:2024 refers to prefabricated metal-enclosed and solid-insulation enclosed (both hereinafter called enclosed) switchgear and controlgear assemblies for alternating current of rated voltages above 1 kV and up to and including 52 kV as specified in IEC 62271 200 and IEC 62271 201, and to other equipment included in the same enclosure with any possible mutual influence. This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Structure of document updated.
b) Updated references to IEC 62271-200:2021 and IEC 62271-1:2017.
c) Addition of criteria for the extension of validity of type tests from functional unit(s) with a different insulating gas to the functional unit to be validated.
d) Figure 5 for the validation of a design modification was added.
e) Clause B.7 for the extension of validity of type test for a GIS with insulation gas A to insulation gas B was added.
