Abstract
An arc fault current detector for an electricity supply having at least two supply conductors (P1, P2) comprises a coil (L1) disposed adjacent to but not surrounding at least one of the conductors and inductively coupled thereto. A circuit (14) is connected to the coil for detecting a signal induced in the coil having frequency characteristics corresponding to an arc fault in the supply.
