The main factorsthatdetermine the magnitude,andotherimportant characteristics of a short circuit current are, among others, the energy capacity of the source of current, the impedance of the power source,the characteristics of the portion of the circuit that is located betweenthe source and the point of the fault, andthe characteristics of the rotating machines thatare connected to the system at the time of the short circuit. The machines, whether a synchronous generatoror either an induction or a synchronous motor, are all sources of power during a short circuit condition.
