New IEEE Standard – Inactive – Superseded. Information and recommendations for the type testing of thyristor valves for high-voltage directcurrent (HVDC) power transmission systems are provided. These tests cover only the principal tests on the valves and do not include tests of auxiliary equipment associated with the valves.<\/p>\n
