The catalog presents a self-powered energy harvesting sensor designed to monitor and protect electrical assets, enhancing reliability and providing early detection for potential problems. The sensor is used to monitor dynamic and static contact connection of electrical connection such as the bus-bar joints, the cable connector, the transformer inlet and outlet and other key parts. It provides continuous monitoring based on a network of sensors for high-voltage and low-voltage distribution network including LV distribution room, substation and power grid. The system also includes features like data acquisition, threshold algorithm setting, over limit alarm, data storage, and information upload.
