Question: A 24-kV feeder (line) supplies a single-phase load through a step-down transformer. The feeder impedance is 50 j400 , the transformer voltage rating is 24/2.4

A 24-kV feeder (line) supplies a single-phase load through a step-down transformer. The feeder impedance is 50 j400 , the transformer voltage rating is 24/2.4 kV, and the (series) impedance is 0.2 j1.0 referred to the low-voltage side. The feeder sending-end voltage, |Vs|, is adjusted so that at full load, 200 kW at 0.9 power factor lagging is supplied to the load at a voltage |VL|full load = 2300 V. a) Find |Vs|. Hint: Refer the feeder impedance to the secondary side. b) Find |VR|, the feeder receiving-end voltage (voltage at the primary winding). c) Find the overall transmission efficiency (i.e., = Pload/(Pload Plosses))
