Fault current calculations can be done for first‐cycle current magnitude or interrupting current magnitude. The theory of symmetrical components and the synthesis of sequence networks for three‐phase power systems are instrumental for solving most unbalanced problems such as asymmetrical short‐circuit and open‐circuit faults.

For calculations of maximum short-circuit currents to select electric power system equipment, a fully loaded industrial power system is recommended because it has the largest number of motors connected and contributing to short-circuit current.
Consequently, ÒhotÓ or rated load resistance values are usually accepted for these calculations. This book is intended to bridge the gap between formal engineering texts and more popularly accessible descriptions of electric power technology. I discovered this gap as a graduate student struggling to understand power systems—especially trans-mission and distribution systems—which had always fascinated me but which now.

In an electric power system, a fault or fault current is any abnormal electric 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. The prospective short-circuit current (PSCC), available fault current, or short-circuit making current is the highest electric current which can exist in a particular electrical system under short-circuit conditions. It is determined by the voltage and impedance of the supply system.
