Abstract

This recommended practice contains information and recommendations for the type testing of thyristor valves for high-voltage direct-current (HVDC) power transmission systems. Other equipment tests, such as development tests, production sample tests, routine tests, tests for the determination of losses, commissioning tests, and site tests are not within the scope of this recommended practice. Furthermore, the tests given here cover the principal tests on the valves only and do not include tests of auxiliary equipment associated with the valves, such as cooling system components. This recommended practice applies to any type of line-commutated indoor thyristor valve, with metal-oxide surge arresters connected between the valve terminals, used in converters for HVDC power transmission systems. Any modifications to these tests and/or additional tests required for outdoor valves are to be considered separately.
