The BHG-DSCL Single-Phase Grounding Management System is a comprehensive fault management system integrating fault circuit selection, single-phase grounding handling, overvoltage suppression, bus voltage monitoring, and fault online recording. It is designed to achieve rapid fault control and intelligent processing, while also meeting the hardware and software conditions for power Internet of Things construction, such as remote fault diagnosis, intelligent analysis, and big data storage. This system is suitable for cable networks, overhead networks, and mixed networks that use neutral points not grounded or neutral points grounded through an arc suppression coil.

The BHG-DSCL Single-Phase Grounding Management System was developed against the backdrop where the gradual inability of the small current grounding operation to fully meet the current development status and reliability requirements of the power system. It leverages the technical accumulation of rapid switching technology and arc extinction line selection, combined with the basic principle of high selection rate in high current grounding operation. It maintains the reliability advantage of the non-effective grounding neutral system at medium voltage, while also addressing a series of issues caused by grid development, such as low selection rate, high grounding current, arc overvoltage, resonance overvoltage, cable explosion, and low level of intelligence.
