engineering recuitment GATE EE 2023-24 Test Series Power Systems Fault Analysis Line To Line To Ground Fault
The reactance data for a power system is shown in the figure in per unit on a common base is as follows.
G1: X1 = X2 = j0.1, X0 = j0.05
G2: X1 = X2 = j0.1, X0 = j0.05
T1: X1 = X2 = j0.25, X0 = j0.25
T2: X1 = X2 = j0.25, X0 = j0.25
Line: X1 = X2 = j0.3, X0 = j0.5
