A 30kva, 6000/230v, 50hz single phase transformer has hv and lv winding resistances of 10.2 and 0.016 respectively. the equvalent leakage reactance as referred to hv side is 34 find the voltage to be applied to the hv side in order to circulate the full load current with lv side short circuited. also estimate the full load % regulation of the transformer at 0.8 lagging power factor.
