Voltage sourced converter (VSC) valves for high-voltage direct current (HVDC) power transmission. Electrical testing1 Scope This International Standard applies to self commutated converter valves, for use in a three phase bridge voltage sourced converter (VSC) for high voltage d. c. power transmission or as part of a back to back link. It is restricted to electrical type and production tests. The scope of this standard includes the electrical type and production tests of dynamic braking valves which may be used in some HVDC schemes for d. c. overvoltage limitation.
