A synchronous generator is connected through a transformer and a transmission line to a synchronous motor. The rated voltage and apparent power of the generator serve as the base quantities for this power system. On the system base, the per unit subtransient reactances of the generator and the motor are 0.15 and 0.40 respectively, the series reactance of the transformer is 0.10, and the series reactance of the transmission line is 0.20. All resistances may be ignored. The generator is supplying rated apparent power and voltage at a power factor of 0.85 lagging, when a three-phase synchronous fault occurs at the terminals of the motor. Find the per-unit subtransient current at the fault, in the generator, and in the motor.
