Research and Analysis of Small Current Grounding Line Selection System
Journal of Physics: Conference Series, 2022 Abstract In the small current grounding system, because the short-circuit fault of single-phase grounding accounts for more than 80% of the total short-circuit fault, the selection of single-phase grounding fault line is still the main problem in electrical engineering.

A new active method for ground fault location in small current grounding system [PDF]
2018 18th International Conference on Harmonics and Quality of Power (ICHQP), 2018 A new method for single-phase grounding fault location in small current grounding system is proposed, in which thyristor-based signal generator (SG) and signal detectors (SD) are included. The thyristor-based SG is connected between the phase line and ground, and SDs are arrayed along the distribution lines. After a single-phase grounding fault occurs,
