High-voltage switchgear and controlgear - Part 207: Seismic qualification for gas-insulated switchgear assemblies, metal enclosed and solid-insulation enclosed switchgear for rated voltages above 1 kV
IEC 62271-207:2023 applies to- gas-insulated switchgear (GIS) assemblies- for alternating current of rated voltages above 52 kV complying with IEC 62271-203, and- for direct current of rated voltages including and above 100 kV,- for indoor and outdoor installations, including their supporting structures,- AC metal-enclosed switchgear and controlgear assemblies for rated voltages above 1 kV and up to and including 52 kV complying with IEC 62271-200, ground or floor mounted, intended to be used under seismic conditions, and- AC solid-insulation enclosed switchgear and controlgear assemblies for rated voltages above 1 kV and up to and including 52 kV complying with IEC 62271-201, ground or floor mounted, intended to be used under seismic conditions.This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. It also cancels and replaces, through merging, the first edition of IEC TS 62271-210 published in 2013.This edition includes the following significant technical changes with respect to the previous edition:a) modification of the minimum voltage rating from 52 kV to above 1 kV in order to include medium voltage equipment previously being within IEC TS 62271-210 scope;b) further harmonisation of qualification procedures with the revised IEEE Std 693-2018 [1], Annex A and Annex P, including1) matching this document's required response spectra with IEEE Std 693-2018 performance level spectra and IEC TS 62271-210 spectra,2) addition of a step-by-step procedure assisting the user of this document to select an appropriate seismic qualification level combining seismic integrity with cost-effective design,3) addition of analytical earthquake component combination techniques, and4) reference to publicly available accelerograms specially developed to match the IEEE Std 693-2018 spectra for testing and analysis purposes, since this document and IEC TS 62271-210 spectra are identical in shape with IEEE Std 693 spectra.c) various enhancements of test procedures;d) addition of minimum contents for seismic qualification reports;e) scope extended to cover DC GIS including and above 100 kV.
