Given: 150kVA 2400V/240V 60 Hz transformer. Open circuit test on the 240V winding of the transformer gives: o VocO= 240V loc = 16.75A Poc=580 Watts Short circuit test was done with the low voltage winding short circuited. Vsc= 63V Isc= 62.5A Psc = 1600 Watts Exciting admittance, conductance, and susceptance. Equivalent primary impedance, reactance, and resistance. For efficiency of the transformer at the rated load at 0.8 lagging power factor.
