A 50 Hz, 110 kVA single phase transformer has a voltage ratio of 11000/440 V. The iron loss measured on open circuit is 1100 W. With the secondary winding short circuited, a voltage of 500 V is applied to the primary to produce full load current, with the wattmeter reading 1000 W. When a current of 250 A at 0.8 lagging power factor is taken by a load connected to the LV terminals with a primary voltage of 11000 V, calculate the following: ) the secondary terminal voltage the voltage regulation the efficiency
