JC-OM200 Lightning Arrester Online Monitoring System

The JC-OM200 arrester online monitoring device realizes the monitoring of the insulation performance of the metal zinc oxide arrester. The online monitoring of the arrester requires two devices: the JC-OM200 arrester online monitoring device and the JC-OM200/PT bus voltage online monitoring device, which can monitor the full current of the arrester in real time. , Resistive current, capacitive current, number of lightning strikes, lightning strike time, through analysis and fitting processing of the monitored data, combined with the on-site working conditions, the leakage current of the porcelain sleeve caused by the pollution or internal moisture of the arrester can be found in time Or increase the leakage current of the insulating rod to avoid accidents.
