Question

A 10 MVA, 6·6 kV, 3-phase star-connected alternator having a reactance of 20% is connected through a 5 MVA, 6·6 kV/33 kV transformer of 10% reactance to a transmission line having a resistance and reactance per conductor per kilometre of 0·2 Ω and 1 Ω respectively. Fifty kilometres along the line, a short circuit occurs between the three conductors. Find the current fed to the fault by the alternator.​
