放电计数器增加了光电报警指示，正常运行时出现绿色、指示灯，当避雷器泄露电浪超过警戒值时见出出红色指示灯，可于避雷器的在线检测。
Discharge counter adds photoelectric alarm indication, green and indicator lights appear in normal operation. When the lightning arrester leaks the wave beyond the warning value, red indicator lights appear, which can be used for on-line detection of lightning arrester.
避雷器监测器除了具有监测避雷器放电动用的功能外，还能监测避雷器泄漏电流变化，对避雷器的运行质量及时给出可靠的数据，防止事故的发生，提高电力系统运行的可靠性。
The surge arrester monitor not only has the function of monitoring the discharge of the arrester, but also can monitor the change of the leakage current of the arrester. It can provide reliable data for the operation quality of the arrester in time, prevent the occurrence of accidents and improve the reliability of the operation of the power system.
