Abstract
What is BS EN 62271-112 – High voltage switchgear and controlgear about?
BS EN 62271-112 is a part of the IEC 62271 series that 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 BS EN 62271-112 are intended to extinguish the secondary arc remaining after clearing faults on transmission lines by the circuit-breakers.
