Analyze three phase power system as shown in figure subject to three phase symmetrical fault occurred at bus 2 and compare voltages at different buses to analyze effects of faults on neighboring buses. Analyze contribution of adjacent buses in terms of fault currents and Compare currents flowing in the lines connecting different buses of three phase power system. Pre fault voltage at each bus is Vr = 1+ 0j = 1 < 0°. Pre fault currents are assumed to be zero. %3D j2 j3 (1) j1 [j1 j1 j1 = 1.67 Zpus j1 j2.55 j1.67
