Current Transformer Selection, Operation & Maintenance ... Transformer: For Selection, Operation, and Inspection & Maintenance In general, large currents (hundreds of amperes) cannot be directly input to powermeters for measuring power. Therefore, the current is passed through a CT (current transformer) prior to measurement. The following are some points regarding selection, operation, and maintenance of CTs....
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.
