A 75 KVA, 24000/480 V, 3-phase transformer is connected in 4-Y. The open-circuit test was performed on its low-voltage side and the following data were recorded. V Line.oc=480 V, Line.oc=4.0 A, P3.oc = 825 W Find the per-phase value of the impedance in Ohms on the LVS. Answers The Core Resistance is: Ohms. The Magnetizing Reactance is: Ohms.
