Fig. 1: IEEE 14-bus system with three phase faults at bus 2.
Fig. 2: Bus voltages at each bus when faults occurred at different buses. The voltages are obtained from
PowerWorld for three phase faults occurred at from bus 1 to bus 14 independently. The values are
for phase A, because of balanced fault, the value of voltages is same for all three phases.
