Original Abstract

At present, digital protections using the admittance principle are able to identify quite reliably a single phase-to-ground connection and to determine the affected feeder. Still, the location of the fault presents a task yet to be solved. The main problem of a fault location consists is a low value of the fault current during a single phase-to-ground fault in com-pensated networks. This work started of an experiment performed in the second half of 2001. The experiment explored a possibility of the identification of a fault location in a circular network by means of ripple-control signal. The work deals with a novel method for a fault location that is able to determine the distance of a fault in a radial network (without a pos-sibility of a circular interconnection) using only values measured in a switching station. The principle of this method was published in 2000 [1]. It presents the application of the method in a real distribution network and the evaluation of the re-sults of this experiment.
