A synchronous generator rated 500kVA,440V with a sub-transient reactance of 0.25 p.u. is supplying a static load of 400kW at 0.8 p.f. lagging at rated terminal voltage. A three phase fault occurs at the generator terminals. Determine:
(i) e.m.f. behind transient reactance
(ii) symmetrical short circuit current during subtransient stage
