JCQ-C1 type monitor of arrester is connected under arrester in serial, it is applied for Zno arrester of 50kV and/or below, used to monitor leakage current and record operation times of arrester, the environment condition shall meet the requirement required by arrester, the feature of monitaor is anti-vibration, electromagneic counting, indicating by current pointer.

Structure and characteristic

Monitor is made up of valve element, rectifier, capacitor, resistor, inductance, trigger circuit, protector, protector, counting circuit, magnetoelectric type finger watthourmeter, current measuement, switching circuit, components, housing and so on. Under normal service conditrons, the leakage current of arrester will be indicated by the magnetoelectric type finger watt-hour meter directly in two steps: 0~5mA and 0~2mA, automatic transmission with lamp indication. At step of 0~10mA, Luminotron goes on, the counter make accumulation counting when the arrester works, when it is full scale, it will return to zero automatically and continue to count, endless duty-cycler operation without reset.
