High-voltage switchgear and controlgear – Part 203: AC gas-insulated metal-enclosed switchgear for rated voltages above 52 kV (Commented Version)

active, Most Current
Organization: IEC
Publication Date: 1 May 2022
Status: active
Page Count: 266
ICS Code (High voltage switchgear and controlgear): 29.130.10
scope:

Commented versions are a valuable improvement upon the conventional IEC Redline Version (RLV). These versions are designed to facilitate a clearer understanding of the revisions made between the prior and current editions of a publication. This enhanced product package incorporates both the most recent edition of the document and the annotated redline version. This combined offering provides users with an easily accessible means to track and comprehend the alterations and additions that have been made, thereby enhancing the utility and effectiveness of the publication for its intended audience.

This part of IEC 62271 specifies requirements for gas-insulated metal-enclosed switchgear in which the insulation is obtained, at least partly, by an insulating gas or gas mixture other than air at atmospheric pressure, for alternating current of rated voltages above 52 kV, for indoor and outdoor installation, and for service frequencies up to and including 60 Hz.

For the purpose of this document, the terms "GIS" and "switchgear" are used for "gas-insulated metal-enclosed switchgear".

The gas-insulated metal-enclosed switchgear covered by this document consists of individual components intended to be directly connected together and able to operate only in this manner.

This document completes and amends, if applicable, the various relevant standards applying to the individual components constituting GIS.
