Answer Posted / sagar patel
Flux is produce Due to alternative action of voltage, and
there is no alternative action in dc supply. Hence, There
is no flux produced in DC supply, so current is not
produced. Due to the dc supply winding get very high
temperature, and it may cause of blast. THAT'S WHY WE ARE
NOT USING DC SUPPLY IN TRANSFORMER.
