CURRENT TRANSFORMER

 

Current Transformer

A current transformer is a device which is used for the transformation of current at a higher value to a lower value with respect to the earth potential. It is used with the AC instruments for measuring the high value of current.

The line current is too high, and it is very difficult to measure them directly. Thus, the current transformer is used which decrease the high value of current into a fractional value which is easy to measure by the instrument.
