Využití indikátorů zemního spojení s detekcí elektromagnetického pole pro lokalizaci zemního spojení

Original language description

The paper is focused on a ground fault location problem in a compensated MV network. For this localization there are used ground fault indicators using electromagnetic fields evaluation of phase conductors or line. These indica-tors are divided into twogroups on the basis of electromag-netic sensors design and both these types of ground indicators are described. Methods which are used by the ground indicators for correct ground fault location are presented and assessed. Fault indication examples of both indicators types are displayed for ground fault on the af-fected line. The sensors of ground fault indicators are installed on MV lines during operation. At present, a test operation in three MV networks with tens of installed indicators is under way.Measuring data are accumulated into the database for future evaluation of the frequent ground fault location in the MV network, it is also possible to assess the type of the ground fault including the prediction of the origination of subs
