The classification model for identifying single-phase earth ground faults in the distribution network jointly driven by physical model and machine learning

Frontiers in Energy Research, 2023
Single-phase earth ground faults are the most frequent faults likely to occur but hard to identify in a distribution system, especially in a neutral ineffectively grounded system.
