what is the purpose of CT,PT..

Answer / praveen kumar gupta

CT is a current instrment Transformer. It is used to
linearly step down the primary current as per the rated
current of controlling device attached with. It is used as
current sensor.

PT is a potential instrument transformer . It is used to
linearly step down the primary voltage as per the rated
voltage of controlling device attached with. It is used as
voltage sensor.
