1.overview
The Intelligent Lightning Arrester Monitoring Terminal can monitor the operating conditions of lightning arresters in real-time, predict and assess their operating status, achieve predictive maintenance, and provide accurate fault alarms, thereby enhancing the level of power automation. This product consists of a data collection unit and an aggregation unit, which wirelessly transmits the lightning strike count and leakage current data of the lightning arresters to the aggregation unit, and then to the monitoring platform for display. It is suitable for monitoring and managing power systems, improving the safety and reliability of the power system.
