摘要：
To address single-phase grounding fault line selection problem in small current grounding distribution network, the paper proposes a fault line selection method based on zero-sequence current (ZSC) increment. The method downshift grounding transformer (GT) tap step-by-step to amplify fault current, defines the line with largest ZSC variation as fault line. The results of typical non-effectively grounding 10 kV distribution network show the rationality and applicability of the proposed method. (C) 2021 The Author. Published by Elsevier Ltd.
