compute the fault currents and voltages at the fault for: (a) a bolted single line-to-ground fault at bus 3, (b) a bolted line-to-line fault at bus 3, (c) a bolted double line-to-ground fault at bus 3. Also, for the single line-to-ground fault at bus 3, determine the currents and voltages at the terminals of generators G1 and G2. Consider the effect of A-Y transformer phase shifts.
