Question: Q5. a) A 6 kV RMS three-phase power supply is applied to a balanced Y-connected three-phase load consisting of three identical (same) impedances of 48236.870 0. Taking the phase to neutral voltage Van as a reference, calculate; (i) The phasor currents in each line. (ii) The total active and reactive power supplied to the load. b) Repeat the problem with the same three-phase impedances arranged in a Delta connection. Take Vab as a reference. -Free Course Hero Question Answer.

Question: A 500 V/230 V single-phase transformer is rated at 30 kVA. The open-circuit test results, with the instruments connected to the high voltage winding, are 300 W, 3.5 A at 500 V, 50 Hz. The short circuit test results, 230 V winding short-circuited, and with the instruments still connected to the 500 V winding, are 1500 W, full load current at 30V. (a) Calculate the approximate equivalent circuit values. (b) Draw the approximate equivalent circuit with the appropriate values referred to the high voltage winding. (c) Draw the approximate equivalent circuit with the appropriate values when referred to the low voltage winding. -Free Course Hero Question Answer.
