Monitor connected with surge arrester operating continuously in power system, measures change of leakage current on-line and recording the discharging times of surge arrester. According to the change of leakage current, the condition and abnormal condition during surge arrester operation could be clarified to avoid accident and improve the reliability of power system operation.Discharge counter connected with surge arrester in series is used torecord the discharging times of surge arrester.
Features of the counter:
1.It is small in volume, light in weight and easy for installation.
2.Adopting wide-angle milliammeter, electromagnetic counter of single/double-pointer can increase the distance available for recording
3.Low residual voltage has no effect to surge arrester.
4.Stainless enclosure can increasing the capacity of anti-corrosion.
