Abstract
An electrical fault detector is shown for installation in electrical network () of the type comprising a first voltage source () and a second voltage source (), each of which have a respective positive rail () connected by a positive concentrator () and a respective negative rail () connected by a negative concentrator (). The detector comprises an inductor () for location in one of: the positive concentrator between the connections of the positive rails thereto, and the negative concentrator between the connections of the negative rails to thereto. The detector also comprises a fault identification device () configured to monitor the voltage across the inductor, and generate a fault signal in response to the voltage across the inductor exceeding a threshold.
