As mentioned open circuit test there would be zero current , and when frequency is doubled it also does not cause any change in current and P.F.
there may cause a little more eddy current in winding, This may cause any trouble in transformer though this test is being done for check winding insulation bearing capacity.
if this answ. is found any mistake or wrong concept kindly text msg in your ans.
