BS EN IEC 61954:2021

This standard BS EN IEC 61954:2021 Static VAR compensators (SVC). Testing of thyristor valves is classified in these ICS categories:

• 29.240.99 Other equipment related to power transmission and distribution networks
• 31.080.20 Thyristors

This International Standard defines type, production and optional tests on thyristor valves used in thyristor controlled reactors (TCR), thyristor switched reactors (TSR) and thyristor switched capacitors (TSC) forming part of static VAR compensators (SVC) for power system applications. The requirements of the standard apply both to single valve units (one phase) and to multiple valve units (several phases). Clauses 4 to 7 detail the type tests, i.e. tests which are carried out to verify that the valve design meets the requirements specified. Clause 8 covers the production tests, i.e. tests which are carried out to verify proper manufacturing. Clauses 9 and 10 detail optional tests, i.e. tests additional to the type and production tests.
