The second generation intelligent wireless monitoring module

The HD-OLM-CH3 lightning arrester status online monitoring system is an integrated intelligent device that monitors the number of lightning strikes of lightning arrester, leakage current, remote signal switch, and the surface temperature in real time. It is equipped with a liquid crystal display and operation buttons,it is convenient to view real-time data, set the alarm threshold and query history alarm data, etc.; it also has an alarm function, Once the real-time data exceeds the set threshold, it will make a alarm sound and light up the corresponding indicator lamp. At the same time, it also has an RS485 wired interface and a 2.4G wireless interface, which can realize the networking of the Internet of Things and LAN systems. Through the networking, real-time data acquisition, automatic monitoring, and remote management of multiple SPDs can be realized, and we can intuitively and effectively understand the operating status and aging status of lightning protectors.
