【 摘 要 】

The paper focuses on the phenomenon of earth faults in mine medium voltage networks with an isolated neutral system. Simplified network models with parallel lines have been considered. The article presents the zero-sequence current in places where in normal conditions earth fault protections relays are installed. For this purpose, the tCad program was used to simulate these networks. Research is preliminary.
