A transformer rated 30 MVA, 33/230 kV and having a reactance of 0.05 pu is connected to the bus-bars of a transfomer which is supplied through two 33 kV feeder cables each having an impedance of 1 + j2 Ω. One of the feeders is connected to a generating station with plant rated at 60 MVA with reactance of 0.10 pu and the other feeder to a station with 80 MVA of generating plant with reactance of 0.15 pu. Calculate the fault current (kA) in the event of a short circuit occuring between the secondary terminals of the transformer. Apply Thevenin's approach
