Question
A 3-ph transmission line operating at 10 kV and having a resistance of 1 ohm and a reactance of 4 ohms is connected to the generating station bus-bars through a 5 MVA step-up transformer having a reactance of 5%. The busbars are supplied by a 10-MVA alternator having 10% reactance. Calculate the symmetrical short-circuit current if it occurs (a) at the receiving end of the line and (b) at the HV terminals of the transformer. Please use Thevenin and Superposition techniques.
