|Definition:|| occurrence of an accidental conductive path between a live conductor and the earth|
Note 1 to entry: The conductive path can pass through a faulty insulation, through structures (e.g. poles, scaffoldings, cranes, ladders), or through vegetation (e.g. trees, bushes) and can have a significant impedance.
Note 2 to entry: Earth faults with negligible fault impedance in a solidly earthed neutral system or in a low-impedance earthed neutral system are also named line-to-earth short-circuits.
