Summary

The paper makes a brief review of the literature on the subject of transient processes in power supply systems and one of the emergencies is a short circuit. The conclusions drawn indicate that the identification of a short circuit due to melting of electrical wires is probable. Although a short circuit is often destructive, there are still no universal criteria or method that would allow a categorical conclusion that a short circuit has been involved to the occurrence of a fire. In addition, the speed of the transition process (and, consequently, the rate of crystallization of wires’ melting) is affected by the characteristics of the source of electricity.
