Patent ID: 6904549

Claim:
A method for fault identification in an electrical radial network having a section cable which can be disconnected and to which a number of outgoers can be connected, which are each monitored by an associated outgoer protective device for the occurrence of a fault, comprising: connecting each outgoer protective device, which is associated with an outgoer, to the section cable and transmitting at least one fault direction signal to a central control device if the fault is on the section cable or is identified as being on the outgoer; sending at least one fault signal to the central control device from at least one of the outgoer protective devices if the fault is on the section cable and all the outgoers are disconnected; determining the outgoer which has been identified to be faulty or a fault on the section cable by the central control device which uses the received fault signals and the received fault direction signals; and disconnecting the outgoer if it is faulty by the associated outgoer protective device or the section cable by the central control device if a fault on the section cable occurs.
