In the following 3-phase power system, the voltage at point a is initially 0.95 pu, and the motor is drawing power 0.95 pu with power factor 0.8 lagging. The reactances are X, = Xm = 0.25 and X = 0.15 (all per unit). IL jXt jX" jX" + E, A ground fault occurs along the dotted line. What is the per-unit fault current?
