A 12kVA, 300V/150V transformer has been tested to determine its equivalent circuit. The open circuit test data when high voltage side is open: loc=1.8A, Poc=100W. The short circuit test data when low voltage side is short circuited: Vsc=40V, Psc=115W. Use approximate equivalent circuit. Calculate the full load output power at 0.85 pf leading.
