suppose we using 3 phase motor of 440 v means what range
of C.T. is require for measuring current ?
Answer Posted / padmanabha prasad
CT range depends on the fullload current of the motor not
voltage. So first find out the motor FLA and based on that
u can select the range of CT(metering). Range should be 0
to FLA*20%)
