A single phase, 50 kVA, 2400/240 v, 60Hz, distribution transformer is used as a step down transformer at the load end of a 2400 v feeder whose series impedance is (1.0 +j2.0) ohms. The equivalent series impedance of the transformer is (1.0 +j2.5) ohms referred to the high side. The transformer is delivering rated load at 0.8 power factor leading and at rated secondary voltage. Neglecting the transformer exciting current. Determine following:
1. The voltage at the transformer primary terminals
2. the voltage at the sending end of the feeder
3. the real and reactive power delivered to the sending end of the feeder
