It is used to verify the reliability of various lightning arrester counter actions. The reliability of the counter action is very important to the power system. It is an important parameter to record the number of lightning strikes by the lightning arrester in normal operation. It can provide the staff of the power system with an important basis for the targeted inspection of the arrester. This instrument is mainly used for high-voltage arresters above 35kV.
