*''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.
