Ways of increasing the productivity of search for a single-phase circuit to earth in the overhead line network of 10 kV with isolated neutral
One of the important tasks of operating 10 kV distribution networks is to quickly locate the damage (QLD) and perform emergency repairs without delay. With a long extension and branching of 10 kV distribution networks, given task can be effectively solved by using special software and hardware that determine the damaged line, the distance to the fault location and operatively relay this information to automated workplaces that integrate the power and information components into the electroinformation network, on the technology «Energy Net». Thanks to the use of appropriate technologies, maximum selectivity, sensitivity and speed, and easy control of all components, the proposed technology can quickly, reliably and, above all, carefully determine the (QLD) locations in a single-phase earth fault (SEF) in an overhead line 10 kV In this article, we consider ways to accelerate and increase labor productivity in terms of organizational and technical measures, speed of movement and the area of search and direct search for the location of the SEF on the overhead line highway. The general idea of improving ways to increase the productivity of repair workers is to use information technologies integrated in the mobile workstation (MWS), located in the vehicle of the repair team.
