In an electric power system, a fault or fault current is any abnormal electric types of faults in power system pdf. For example, a short circuit is a fault in which current bypasses the normal load.


An open-circuit fault occurs if a circuit is interrupted by some failure. In three-phase systems, a fault may involve one or more phases and ground, or may occur only between phases. In a “ground fault” or “earth fault”, current flows into the earth. The prospective short-circuit current of a predictable fault can be calculated for most situations.
