NEUTRAL GROUNDING MODE IN THE 6–35 KV NETWORK THROUGH AN ARCING REACTOR AND ORGANIZATION OF RELAY PROTECTION AGAINST SINGLE-PHASE GROUND FAULTS

The choice of the neutral grounding mode in the 6–35 kV network (or, in other words, the method of neutral grounding) is an extremely important issue in the design and operation. In this article, one of the neutral grounding modes in 6-35kV networks is considered - through an arcing reactor. The choice of the neutral grounding mode in 6–35 kV networks is an extremely important issue in the operation and design of the network. The use of modern neutral grounding equipment in 6–35 kV networks (arc-quenching reactors with lowvoltage shunt resistors and high-voltage neutral grounding resistors) can significantly improve the reliability of networks, automate the search for a damaged feeder and reduce accidents in case of single-phase ground faults.
