What is BS EN IEC 61954 about?
BS EN IEC 61954 defines the 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 BS EN IEC 61954 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 added to the type and production tests.
Who is BS EN IEC 61954 for?
BS EN IEC 61954 on static VAR compensators (SVC) is useful for:
- Electricians and line workers
- Quality assurance team
- Organizations that provide or install SVCs
Why should you use BS EN IEC 61954?
A static VAR compensator is a parallel combination of a controlled reactor and fixed shunt capacitor. Thyristor valves are an important component of SVCs that convert AC to DC and ensure equal distribution of power between individual stations.
BS EN IEC 61954 provides a series of test methods for thyristor valves, like dielectric tests, operational tests, electromagnetic tests and production tests. These test methods focus on different components and functions of the thyristor valves.
These test methods provided in BS EN IEC 61954 can help you evaluate the operation quality and the build quality of the thyristor valves. This will ensure that your SVCs function as intended once installed.
