Cable sheath circulation monitoring system

The high-voltage cable grounding circulation monitoring system is composed of a signal monitoring unit, a data communication unit, and a local sensor unit. It completes the environmental temperature and humidity detection of the high-voltage cable grounding circulation and the grounding box, and transmits the data to the local monitoring panel through the RS485/IEC61850 communication module. The monitoring terminal uses advanced measurement circuits, high-speed MCUs, and stable and reliable sensors to achieve accurate measurement of monitoring signals and reliable data transmission.
