JSM-2 type monitor of arrester is connected under arrrester in serial, used to monitor leakage current and record operation times of arrester. The environment condition shall meet the requirement of arrester, the feature of monitor is anti-vibration, electromagnetic counting, indicating by current pointer.
It use of the arrester energy (surge current and power frequency current) to fetch the voltage on valve element (non-linear resistance), then it charges to the capacitor in single direction through silicon bridge type rectifier, makes the coils of electromagnetic counter discharge with form of DCpower to move the counter, thus, it can realize that the operating times can be recorded.
