PROBLEM
A synchronous generator is connected to an infinite bus through a 138 kV transmission line, as shown in the figure. A three phase fault occurs on the line near the CB1.
Before the short circuit, the receiving-end voltage was 1.0 per unit, unity power factor and the generator was 80 percent loaded, on the basis of its MVA rating. Determine the sub-transient, transient, and synchronous short-circuit currents.
