    Three-generators are interconnected through three transformers and two transmission lines as shown in the figure below. The rated MVA, voltage rating and percentage reactance of the generators and transformers are depicted in the figure. The reactance of the transmission lines shown in the figure are in Ω. Considering the pre-fault voltage as 1 p.u, compute the fault current, if a 3-phase bolted fault occurs at bus 2.

    [IMAGE: Figure from the original question paper with labels: G₁ 50 MVA 11 kV 10%; T₁ 100 MVA 11/132 kV 5%; j25Ω; j10Ω; T₂ 50 MVA 132/6.6 kV 4%; G₂ 50 MVA 6.6 kV 6%; T₃ 50 MVA 132/6 kV 4%; G₃ 50 MVA 6 kV 5%; buses 1, 2, 3]
