A 3-phase, 20 MVA, 13.8 kV wye-connected alternator is connected to a 20 MVA, 13.8 kV Delta/33 kV Wye-grounded transformer. The reactance of the alternator is X1 = X2 = 15%, X0 = 5%, Xn = 0, and that of the transformer X1 = X2 = X0 = 7%. If there is a double line-to-ground fault at the high-tension bus, calculate the ground current. Assume that faults occur at lines "b" and "c" with 20 MVA and 13.8 kV as bases.
