Current Transformer 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. Selecting a CT Check the voltage of the ...
