FIGURE Q2 shows a four bus three phase power system. The generators, transformers and transmission line per unit reactance are given as follows: Generator G1, G2: XG= 0.05 pu Transformers T1, T2: Xt= 0.13 pu Transmission Line 2 – 3: XL = 0.50 pu Bus 1 Bus 2 Bus 3 Bus 4 Line G? FAULT FIGURE Q2 Evaluate the per unit fault current, fault MVA and voltage at all buses if a three phase bolted fault occurs at Bus 2.
