Decision tree-based fault line selection method for mine power systems using transient polarity and 5th harmonic direction dual criteria

To address the difficulty of single-phase grounding fault line selection in mine resonant grounding systems, this paper proposes a decision tree-based fault line selection method integrating transient polarity and 5th harmonic direction dual criteria. The transient polarity characteristics of zero-sequence currents and...
