5G Transmission-based Insulation Monitoring of Mining Cables
Single-phase grounding faults occurring in coal mine networks with ineffectively earthed neutrals have low fault current and insignificant steady-state characteristics,and thereby are hard to detect.Aiming at improving diagnosis effect of single-phase grounding faults in mining areas,a cable insulation monitoring method which utilizes 5 G transmission is proposed in this paper.The structure and key technologies of the proposed dual-end synchronous monitoring method,as well as simulation verification carried out on a three-phase cable model,are described.The factors that may cause errors when applying the method to actual measurements are analyzed and discussed.
