would simultaneously reduce the highly desirable water holding capacity of the
soil.

For the balanced, three phase network shown below assume that all data is per unit on a 100 MVA base except for the transmission line reactance. Assume a 13.8 kV voltage base for the generator and motor, and a 138 kV voltage base for the transmission line.
a) If the system is initially operating unloaded with all voltages at 1.0 per unit, what is the magnitude of the fault current (in amps) if a balanced, three phase fault occurs on the terminal of the motor. You should neglect the dc offset current. b) During the fault from part a, what is the per unit voltage magnitude on the terminal of the generator?
