Answer Posted / rvg
The current at 200v side will be more than what designed
for the transformer and core loss will be more. So
ultimately,transformer will be heated up more faster than
ordinary condition. Depends upon the insulation used for
core construction, and how long u are connected the supply,
there r chances of insulation failiure.
