what happens when the transformer is connected to DC supply?

Answer Posted / shyamkr

when dc supply is given to the transformer,since dc can't
produce fluctuating flux ,it will not induce e.m.f in the
primary winding of the transformer.when this counter emf is
not induced in the primary ,the almost full applied
voltage(except little voltage drop in the primary winding
resistance and leakage reactance) is forced in the primary
winding and it may burn.
as far as secondary is concerned ,no emf is induced in it
because emf doesn't vary in case of dc current.

In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
