Answer / mahesh sali

dc supply given to the x'mer , there is no flux produced
into the transformer due to the absence of frequency ,
cause will be damaged of insulation of x'mer and its get
overheated

Answer / naveen

it will lead to burning of transfotmer because there will
not be any secondary emf hence tranformer will work like a
load itself & due to overheating it will burn.

Answer / guest

When DC is supplied to a transformer the windings in the transformer will make it a electro magnet. There will be no
effect on the secondary but when the supply is interrupted a
voltage will be induced in the secondary.

what is a difference berween line voltage and phase voltage?
