|Definition:|| occurrence of an accidental conductive path between a live conductor and the Earth
NOTE 1 – 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 have a significant impedance.
NOTE 2 – A conductive part between a conductor which may, for operational reasons, not be earthed and the Earth is also considered to be an earth fault.
