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.

Abstract: A method and system for determining a tripping range of an electrical circuit switching device designed to supply power to an electrical installation. The system includes an electronic calculation module which is configured to receive data from at least one vibration sensor integrated into said switching device and which is configured to select, based on spectrograms calculated from temporal vibration signals acquired, a predetermined subset of operational characteristics; apply a prediction model parameterized by supervised machine learning to the values of the operational characteristics so as to obtain an estimated value of cut-off current, and determine, as a function of the estimated value of cut-off current, a tripping range of the switching device amongst: normal tripping, overload tripping, and tripping following a short circuit.
