Arresters are critical electrical devices in power grids used to protect power equipment from overvoltage hazards. The operational status of arresters directly impacts the safety of the power system. Typically, arrester monitors are used to monitor the operation and leakage current of arresters. Due to poor sealing, moisture or humidity may enter the monitor during operation, causing internal components to rust or other issues that prevent the monitor's counter from functioning properly and lead to inaccurate leakage current indications. Therefore, the "Regulations" stipulate that arrester monitors should be inspected once a year.

The reliability of the counter's operation is crucial for the power system as it records an important parameter - the number of lightning strikes an arrester has experienced during normal operation. This information provides essential evidence for power system personnel to conduct targeted inspections and maintenance of arresters.
