A 30000 kVA, 13.8 kV generator with is connected to a bus which supplies two identical motors as shown in the Figure 2.The subtransient reactance of each motor is 25 % on a base of 6000 kVA, 7 kV. The bus voltage at the motors is 7 kV when a three phase fault occurs at the point P. For the fault specified, determine (a) the subtransient current in the fault (b) the subtransient current in breaker A and (c) the symmetrical short circuit interrupting current in the fault and in breaker A.
