A 60-Hz, three winding transformer is rated at 2300 volts on the high side with a total of 300 turns. Of the two secondary windings, each designed to handle 200 KVA, one is rated at 575 volts and the other at 230 volts. Determine the primary current when rated current in the 230 volt winding is at unity power factor and the rated current in the 575 volt winding is at .5 pf lagging. Neglect all leakage impedance drops and magnetizing current.
