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 a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
