Introduction
Some of the related terms defined by the IEC's Electropedia:
- Short-Circuit: accidental or intentional conductive path between two or more conductive parts forcing the electric potential differences between these conductive parts to be equal to or close to zero.
- Short-Circuit Current: an over-current resulting from a short circuit due to a fault or an incorrect connection in an electric circuit.
- Short-Circuit Operation: no-load operation with zero output voltage (Note – Zero output voltage can be obtained when the output terminals are short-circuited).
- Line-to-Earth Short-Circuit: short-circuit between a line conductor and the Earth, in a solidly earthed neutral system or in an impedance earthed neutral system (Note – The short-circuit can be established, for example, through an earthing conductor and an earth electrode).
- Line-to-Line Short-Circuit: short-circuit between two or more line conductors, combined or not with a line-to-earth short-circuit at the same place
- Short-Circuit Current Capability: the permissible value of the short-circuit current in a given network component for a specified duration.
