SF6 Remote-Type Density Relay

The SF6 remote‑transmission density relay is designed to monitor the density of SF6 gas in high‑voltage electrical equipment, acquiring pressure and temperature data in real time and transmitting it remotely. The product is compatible with GIS, circuit breakers, gas‑insulated switchgear, and other devices, supporting voltage ranges from 10 kV to 750 kV and ±800 kV/±1100 kV. It offers robust sealing, precise measurement, and stable operation, enabling timely alerts for gas leakage risks and ensuring the safe operation of high‑voltage equipment. It also supports integration into online monitoring systems.

Surge Arrester Online Monitoring System

The surge arrester online monitoring system collects real-time data such as leakage current and operation counts, continuously tracks equipment operating conditions, and promptly issues early warnings for potential faults like aging or moisture ingress. It is compatible with surge arresters ranging from 10 kV to 750 kV, as well as ±800 kV and ±1100 kV systems, and is widely deployed in substations and high-voltage transmission and distribution networks. With precise measurements and stable performance, the system can be integrated into power‑grid online monitoring platforms, enabling remote visualized management and ensuring the safe and reliable operation of the grid.

Partial Discharge Online Monitoring System

The partial discharge online monitoring system acquires partial discharge signals from high-voltage electrical equipment in real time, identifies insulation defects on the fly, and provides early warnings of potential hazards such as insulation aging and internal discharges. It is suitable for high-voltage equipment including GIS, circuit breakers, and transformers, covering voltage levels from 10 kV to 750 kV, as well as ±800 kV and ±1100 kV. Featuring strong anti-interference capabilities and high detection accuracy, the system can be integrated with power‑monitoring platforms to enable long‑term, continuous online monitoring, effectively mitigating insulation failures and ensuring the stable operation of transmission and transformation equipment.
