A single phase power system is defined as follows; A 25KVA 5000°V generator is connected to a low voltage side of an ideal source transformer which have a turn ratio 1:4. The feeder line is connected between the high voltage side of the source transformer with impedance of 4= 25+ j550 and high voltage side of the load transformer. An ideal load transformer which has 8:1 turn ratio is connected to a load wich have an impedance of Z = 4Z0°n a) Draw the system schematically b) Find the base values of the currents, voltages and the power at generator, feeder line, and the load side. c) Convert the current voltages impedances and the power in per unit values.
