A 3-phase, 5 MVA, 6.6 kV alternator with reactance of 8% is connected to a feeder of series impedance of 0.12 + j0.48 2/ph/km through a transformer rated at 3 MVA, 6.6 kV/33 kV and has a reactance of 5%. Determine the fault current supplied by the generator operating under no-load with a voltage of 6.9 kV, when a 3-phase fault occurs at a point 15 km along the feeder. Ans: 465.22-87.6° A
