Özet
Earth faults are detected and located by using zero sequence current magnitude in the field. However, distribution networks may have different neutral earthing strategies, generally, preferred by distribution system operators or enforced by regulatory bodies. Different earthing practices create difficulties for earth fault location problems. In addition to this difficulty, heavy underground cable usage increases the capacitive current levels of the system. Circulating capacitive currents during the single line to ground faults may further hinder the effectiveness of earth fault location algorithms. This work presents zero sequence magnitude-based fault location performance on 151-node distribution network considering different earthing methodologies and line types.
