Fault on mv cable and the flag down .when operator patrole the feeder he can konws the fault pass throughen this circuit .
My ques

When i open the ct secondary terminals is there any mistake ?
And is there any current inside the ct at the normal condition?

Thanx alot .

RE: EFU ct's

Definitely don't open the CT secondary terminals while the cable is energised. Probably don't mess around with CT circuits if you don't have any experience with them, they can be quite dangerous.
