2. The sequence reactances of a three phase alternator are X1 = x2 = 0.15 and Xo = 0.05 pu, based on the machine rating of 30MVA and 13.2 kV. The alternator is connected to a transmission line having X1 = X2 = 0.1 pu and Xo = 0.4 pu. A line to line fault occurs on the line at the receiving end. Draw the sequence networks for the faulted system and calculate the fault current.
