Resumen (inglés):

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.
