The synchronous generator in Figure is operating at rated MVA, 0.9 p.f. lagging and at $2\%$ above rated voltage when a bolted three-phase short circuit occurs at bus 1. Calculate the per-unit values of (a) subtransient fault current; (b) subtransient generator and motor currents neglecting prefault current; and (c) subtransient generator and motor currents including prefault current. Note: take the lecture example as a reference.
