Abstract

The article describes the features of the operation of devices that define the fault place of overhead lines. Research objective is definition of features of use of faults indicators to distributive electric networks and a technique of definition of setting points and quantity of indicators. The technique consists in studying of process of revealing of a fault by means of parametres of an emergency operation and the analysis of demands and features at arrangement of faults indicators in network. Results of research are certain making techniques of an arrangement of devices which analyse a condition of a supply network and define emergency sections with taking into account the basic theoretical rules of their work and characteristics. Research results testify to necessity of conducting of the further development in direction of refining the gained results and definition of the system approach for automation of search and localisation of fault place in powers line.
