A 3-phase transmission line operating at 10 kv and having a resistance of 1ω and reactance of 4 ω is connected to the generating station bus-bars through 5 mva step-up transformer having a reactance of 5%. The busbars are supplied by a 10 mva alternator having 10% reactance. Calculate the short-circuit kva fed to symmetrical fault between phases if it occurs w.R.T 10000 kva is base kva. (i) at the load end of transmission line (ii) at the high voltage terminals of the transformer 2.
