A single-phase load is fed through a 66-kV feeder whose impedance is 120+j 400 Q and a 66/6.6 kV transformer whose equivalent impedance (referred to LV) is 0.4 + 1.5 . The load is 250 kW at 0.8 leading power factor and 6 kV. (a) Compute the voltage at the sending-end of the feeder. (b) Compute the voltage at the primary terminals of the transformer (c) Compute the complex power input at the sending-end of the feeder
