The equivalent circuit impedances of a 20-kVA, 8000/240-V, 60-Hz transformer are to be determined. The open-circuit test and the short- circuit test were performed on the primary side of the transformer, and the following data were taken: Open-circuit test (on primary) Short-circuit test (on primary) = 8000 V V- 489 V 0.214 A -2.5 A P- 400 W P=240 W Find the impedances of the approximate equivalent circuit referred to the primary side, and sketch the circuit.
