It depends on circuit breaker. If sensing eliment is
installed inside the CB or outside the CB. Like MCCB with
maganetic trip latch will operate. Same way MCB will also
operate as it has short ckt and O/L sensing eliment. But
large circuit breakers have relays outside.

Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.????
