To deal with the faulted line selection in the single-phase to ground faults caused by neutral non-effective grounding in the distribution network, a new method by using zero-sequence admittance is proposed in this paper. Compensation admittance, which amplifies the difference in zero-sequence admittance between the faulted line and the unfaulted line, is convenient for the formation of the criteria for value setting in engineering. To eliminate the blind zone, combining the criterion of the susceptance error in the compensated admittance with the phase angle criterion helps form a new algorithm to identify the single-phase to ground faults in the neutral non-effectively grounded system. Results of simulation tests show that the algorithm has nothing to do with the network structure and parameters, fault conditions and fault resistance, significantly escalating the successful selection of the faulted line.
