Part 112: Alternating current high-speed earthing switches for secondary arc extinction on transmission lines

(IEC 62271-112:2021); German version EN IEC 62271-112:2021
Class/Status: Standard, valid
Released: 2023-01
VDE Art. No.: 0600403

This part of IEC 62271 applies to AC 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.
