[0002] With the rapid development of power systems, the safe and stable operation of power distribution networks is crucial for power supply. Grounding faults are one of the common fault types in power distribution networks, which can cause equipment damage, power interruption and even personal safety accidents. Therefore, quickly and accurately diagnosing grounding faults is of great significance to ensure the reliability of the power grid and the efficiency of maintenance.
