Method for fault identification in an electrical radial network, an application of the method and an arrangement for fault identification in an electrical radial network

摘要

A Device for fault identification in an electrical radial network has a section cable and a number of outgoers which can be connected thereto. The device provides that a central control device uses fault direction signals and/or fault signals which are formed by outgoer protective devices which each monitor one of the outgoers to determine the position of the fault in the radial network and, if there is a fault on the section cable, for the central control device to initiate its disconnection.
