A single-phase 100-kVA, 2400/240-volt, 60-Hz distribution transformer is used as a step-down transformer. The load, which is connected to the 240 volt secondary winding, absorbs 83 kVA at 0.79 power factor lagging and is at 215 volts. Assume an ideal transformer. (Assume the phase angle of the secondary winding voltage is 0°.) (a) Calculate the primary voltage. (Enter the magnitude in V.) V (b) Calculate the load impedance (in ?). (Enter your answer in polar form. Enter the phase angle in degrees.) ? ° ? (c) Calculate the load impedance referred to the primary (in ?). (Enter your answer in polar form. Enter the phase angle in degrees.) ? ° ? (d) Calculate the real power (in kW) and the reactive power (in kvar) supplied to the primary winding. (Use the load convention.) real power kWreactive power kvar
