Application of Travelling Wave Technology in Distribution Circuit Grounding Fault Detection

The grounding fault situation in distribution network is more complex, and the fault line selection reliability, fault location accuracy will affect the power supply reliability. Combining the travelling wave principle of fault line selection and fault location, the grounding fault detection technology in distribution line based on the travelling wave method was researched. The results of practical application show that this grounding fault detection system method can accurately calculate and solve the fault parameters, which can improve the fault line selection removal efficiency and the fault location accuracy.
