Hi Pot Test of metalclad switchgear
Hi Pot Test of metalclad switchgear
(OP)
Dear All,
I have seen during hi pot test of switchgear, PT takes out of circuit. So PT won't subjected to Hi potential test.
But in actual sevice condition, PT will be in circuit and exposed to hi voltage like other component during abnormal condition.
Please reply.

If the PT isn't rated for the test voltage you are using for the switchgear, then test it at a suitably reduced voltage that it is rated for.

I got answer.
Hope same time of help in future.

This is often not convenient and hence PTs are tested separately.
