YNFD-H arrester discharge counter calibrator is used to verify the reliability of various 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.
