The following data were obtained when a 25 kVA, 2300/460 V, 50 Hz transformer was subjected to open- circuit test: Eoc = 460 V, Ioc = 1.48 A and Poc = 460 W. Determine the (a) resistance representing the core loss, (b) magnetizing reactance of the core and (c) magnetizing current. Subject: Electrical Apparatus and Devices
