Question: A 1 0 kVA, 1 0 0 0 V / 2 0 0 V , 5 0 Hz , single phase transformer has HV and

A 10 kVA, 1000 V /200 V,50 Hz, single phase transformer has HV and LV side winding
resistances as 1.1 and 0.05 respectively. The leakage reactance of HV and LV sides are
respectively 5.2 and 0.15 respectively. Calculate [i] the voltage to be applied to the HV side
in order to circulate rated current with LV side shorted, [ii] Also calculate the power factor under
this condition.
