Extremely low frequency‐based faulty line selection of low‐resistance grounding system
The single‐phase‐to‐ground faulty line selection methods based on the signals of the frequency above 10 Hz has a low discrimination of fault characteristic signal and characteristic signal may be covered by noise in cases of high‐resistance fault.
