IEC 60700-1 Ed. 1.1 b:2003, Thyristor valves for high voltage direct current (HVDC) power transmission - Part 1: Electrical testing

Applies to thyristor valves with metal oxide surge arresters directly connected between the valve terminals, for use in a line commuted commutated converter for high voltage d.c. power transmission or as part of a back-to-back link. Retricted to electrical type and production tests. Tests are based on air insulated valves.
