Answer / karthik_elec

ther is no primary winding in the ct, the the load current
carrying cable only act as a primary winding

Answer / sanjeev shukla

actually we cant say about the no. of turns of the primary winding of the ct but the rating of the c.t is 800/400/200/1 means what should be the primary current secondary current must be 1 amps

Answer / anonymous

(Secondary Turns)*(Secondary Current)
--------------------------------------
(Primary Current)
