High-voltage switchgear and controlgear - Part 112: Alternating current high-speed earthing switches for secondary arc extinction on transmission lines

active, Most Current
Organization: CENELEC
Publication Date: 1 October 2013
Status: active
Page Count: 30
ICS Code (High voltage switchgear and controlgear): 29.130.10
ICS Code (Other switchgear and controlgear): 29.130.99
scope:

This part of IEC 62271 applies to a.c. high-speed earthing switches designed for indoor and outdoor installation and for operation at service frequencies of 50 Hz and 60 Hz on systems having voltages of 550 kV and above.

High-speed earthing switches described in this standard are intended to extinguish the secondary arc remaining after clearing faults on transmission lines by the circuit-breakers.
