IEEE 857 1996 Edition, December 10, 1996 Recommended Practice for Test Procedures for High-Voltage Direct- Current Thyristor Valves
More info
Description / 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.
