why C.T secondary are rated 5A generally?
Answer Posted / anthony
relays are connected to the sec. of a ct . If a large
rating is proposed for the sec. of the ct then it would
mean that the magnetising current (emag. relays) would be
high too, since on the sec. side you have an inductive
relay. This would actually present itself as a load on the
sec.of the ct .
