This paper demonstrates the classical short circuit (SC) test of a synchronous machine. This simulation gives a full analysis of a sudden symmetrical short-circuit of an unloaded synchronous generator. The intention is to check the transient characteristics by short-circuiting the three terminals of an unloaded synchronous generator, and the solution is then extended in so that it can be applied to a loaded machine as well. The system is assumed to be unloaded before the fault occurs and that the magnitude and phase angles of all the generator internal emfs are the same. Although, the majority of the faults occurring in practice on a power system are unsymmetrical between the phases, the symmetrical fault is important because, although rarer, it is more severe.
