Medium-voltage faults location and handling with the help of powerline communication systems

The paper deals with detection, localization and handling of single-phase-to-ground faults on medium-voltage power distribution lines. Fault location principle of zero-sequence current phase is described. Results of MATLAB simulations are provided. Design of a system for localization of a single-phase grounding fault section in distribution network is proposed. Arrangement of power line communication systems and possible scenarios of using them to solve this type of problems are discussed.
