For the determination of one phase parameters of 20kVA 20000 / 480V, 60Hz transformer Data were obtained by performing the following experiments. Blank running test: Vb: 480V Ib: 1.51A Pb: 271W Short circuit test: Vk: 1130V Ik: 1A Pk: 480W a) Find the approximate equivalent circuit parameters with respect to the primary. b) When connected to the transformer to a load with a power factor of 0.8, it draws 42A at 480V. It Calculate the yield in the conditions.
