The main factors of insufficient selection principle for small current grounding.
The automatic line selection technology for small current grounding is a challenging problem. Its difficulty mainly lies in the fact that during a single-phase grounding fault, the fault signal is small, unlike other fault types such as two-phase short circuit or two-phase grounding short circuit, which have much larger fault signals. The types of single-phase grounding faults are complex and uncertain, including full grounding faults, intermittent arc grounding, grounding with unstable resistance, and grounding through branches (high-resistance grounding), among others.
