HVDC converter station - Wikipedia· The converter is usually installed in a building called the valve hall.Early HVDC systems used mercury-arc valves, but since the mid-1970s, solid state devices such as thyristors have been used. Converters using thyristors or mercury-arc valves are known as line commutated converters.In thyristor-based converters, many thyristors are connected in series to form a thyristor valve, and each ...

Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
Current Transformer Specification Grounding Transformer with built in local power supply can be used as a local transformer. When the relay is located some distance from the CT, the burden is increased by the resistance of the pilot wires. ) The metering CTs shall be suitable for 11 KV, 50Hz, effectively earthed neutral system. 13 (ANSI) Burden of current transformer.
