IEEE Transactions on Power Delivery, 2022
The single-phase to ground fault (SPGF) is very common in power grids. To decrease the fault’s influence on the power supply’s reliability, the neutral point is usually grounded via the Petersen coil, significantly reducing the outage rate. Nevertheless,

Single-Phase Ground Fault Location of Distribution Network with DG Based on CEEMD
2020 Asia Energy and Electrical Engineering Symposium (AEEES), 2020When a single-phase ground fault occurs in the resonant grounding system, the arc suppression coil only compensates for the power frequency zero sequence current, but has little effect on the non-power frequency zero sequence current.
