A single-phаse twо-winding trаnsfоrmer is rаted 20 kVA, 480/120 vоlts, 60 Hz. During a short-circuit test, where rated current at rated frequency is applied to the 480-volt winding (denoted winding 1), with the 120-volt winding (winding 2) shorted, the following readings are obtained: V1=35 volts, P1 = 300 W. During an open-circuit test, where rated voltage is applied to winding 2, with winding 1 open, the following readings are obtained: I2 =12 A, P2 = 200 W. Find the following: a. From the short-circuit test, determine the equivalent series impedance Zeq1 =Req1 + jXeq1 referred to winding 1. Neglect the shunt admittance. b. From the open-circuit test, determine the shunt admittance Ym = Gc jBm referred to winding 1. Neglect the series impedance. Useful formulaes-3.pdf
