The International Electrotechnical Commission (IEC) has released IEC 62501:2009+A1:2014+A2:2017 CSV. This consolidated version of the standard and amendments applies to voltage sourced converter (VSC) valves for high-voltage direct current (HVDC) power transmission – Electrical testing, and is now available on the IEC webstore.
Description: “IEC 62501:2009+A1:2014+A2:2017 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.”
