On-Line Monitoring of HV Transmission Cables Based on a New Criterion Established with Sheath Current

On-Line Monitoring of HV Transmission Cables Based on a New Criterion Established with Sheath Current

In order to timely discover the faults in the high-voltage cable cross-interconnected grounding system, this paper constructs a new criterion based on the ground currents at both ends of the metal sheath of cable to classify and locate the faults of power cables. Firstly, the amplitude and phase of...
