Abstract
A method for locating an electrical arc fault upstream or downstream of an electrical protection device connected in series in an electrical circuit between an electrical energy source and an electrical load, the source supplying a supply current to the electrical load. The method includes the measurement of several electrical quantities linked to the supply current, the detection of a simultaneous variation of at least two electrical quantities linked to the supply current, the confirmation of the presence of the arc fault, and the determination of the position of the arc fault upstream or downstream of the protection device. Also, a protection device can implement such a method.
