Q3- three phase step down transformer 1250 KVA, 11000/2200 V, 50 Hz . The resistance /phase and leakage reactance/phase of the primary winding are 0.78 ohm and 4.8 ohm and the corresponding values for the secondary winding are 0.01 ohm and 0.06 ohm respectively if the primary winding is connected in delta and secondary in star calculate: 1) The voltage to be applied at normal frequency to the primary to circulate full-load through it when the secondary is short-circuited ii) The full load copper loss
