Answer / dinesh lokhande

Actually above answer is not correct as it is the full load
current.No load current is approximately 4 to 5 % of rated
full load current. hence considering the terminals (i.e HV
side or LV side) the current drawn from source will be 4 to
5 % of respective side rated current.

Answer / satya

the charging current is about 6 times the full load current
about 2000 amps but that will be for mill seconds

Answer / gunasekaran

for good transformer it should be 0.5%of full load current
for normal it may be upto 1%

Answer / pulkit

max current when on load wil be 390 amp drawn by the Hv wdg
of t/f and when on no load the transformer primary losses
occur on the basis of elctic flux principle in which when evr
the current flows in a loop,there is loss in the form of
magnetic field energy that is created arround the primary
coil.it is 1 % of the hv wdg current.

max. current drawn is 606.1 amps
