DESCRIPTION

BS EN 62271-207:2012


This standard BS EN 62271-207:2012 High-voltage switchgear and controlgear is classified in these ICS categories:
  • 29.130.10 High voltage switchgear and controlgear
IEC 62271-207:2012 applies to gas-insulated switchgear assemblies for alternating current of rated voltages above 52 kV for indoor and outdoor installations, including their supporting structure. This second edition of IEC 62271-207 cancels and replaces the first edition published in 2007. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- modification of the minimum voltage rating from 72,5 kV to above 52 kV;
- harmonisation of qualification procedures for GIS with IEEE 693:2005 Annex A and P by modifying the response spectra;
- modification of the test procedures;
- addition of criteria of allowed stresses;
- addition of dynamic analysis CQC. The contents of the corrigendum of January 2013 have been included in this copy.
