A synchronous generator and motor are rated 30MVA, 13.2 kV, and both have subtransient reactances of 20%. The line connecting them has a reactance of 10% on the base of the machine ratings. The motor is drawing 20MW at 0.8 power-factor leading and a terminal voltage of 12.8 kV when a symmetrical 3-phase fault occurs at the motor terminals. Use superposition concepts to find the fault current in amperes
