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) Voc-8000V Vsc-489V loc-0.214A Isc-2.5A Psc-240W Poc 400W Find the impedances of the approximate equivalent circuit referred to the primary side and sketch that circuit.
