IEC TR 62271-307:2024
High-voltage switchgear and controlgear - Part 307: Guidance for the extension of validity of type tests of AC metal and solid-insulation enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV
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.
