2. (45 Points) A single-phase power system is shown in Figure P2-1. The power source feeds a 50-KVA 10/2.1-kV transformer through a feeder impedance of 38.2 +j140 2. The transformer's equivalent series impedance referred to its low-voltage side is 0.10 +j0.4 2. The load on the transformer is 90 kW at 0.8 PF lagging and 2000 V. (a) What is the voltage at the power source of the system? (b) What is the voltage regulation of the transformer? (c) How efficient is the overall power system? 38.20 1400 w 0.100 0.400 w Load 90 kW 0.80 PF lagging scuro Source Transformer Load Feeder (transmission line)
