a single phase 440V 80kW load with a lagging Pf of .8 is supplied through a feeder of .6+j1.6 ohms and a single phase 100 kVA, 220/440 V transformer. the equiv impedance of the transformer referred to the High Voltage side is 1.15+j4.5 ohm.
draw a schematic showing the transformer connection, determine the voltage at the high voltage terminal of the transformer and the voltage at the sending end of the feeder.
