Background

In an electric power system, a "short circuit" refers to a connection between a phase and a phase or between a phase and ground (or neutral) other than a normal operation condition of the electric power system. The basic form of short-circuiting in three-phase systems is: three-phase short circuit, two-phase short circuit, single-phase ground short circuit, two-phase ground short circuit. A very large current flows when an abnormal connection (i.e., short circuit) occurs between the phases or between the phases and the ground (or neutral line). The current value is much greater than the rated current and depends on the electrical distance of the short-circuit point from the power supply. The short circuit is a low-resistance short circuit between conductive parts with different potentials, and is equivalent to that a power supply is directly connected into a closed loop through a wire without passing through a load.
