The Design of Location System for Single-Phase Grounded Fault in Distribution Network Based on Zero-Sequence Current

Abstract:

In this paper, A location system for single phase grounded fault in distribution network is proposed and it is based on the phase of zero-sequence current. The system is composed of central station and nodes installed on the power line, and their functions are illustrated in this paper. The principle of the method is shown and experiments are carried out. The results show that the feasibility of the method. The advantage of this method is it’s short time to detect. The method is Applicable to detect the faulty segment for neutral point non-grounded system with grounded resistance less than 1kΩ.
