lightning arrester surge arrester counter

It's used to monitor the discharging freqency and operation condition of lightning arrester. Alarm if failure happens.

 Introduction:

JS(Y) Series lightning strike detector, a high voltage product, is installed in series with lightning arrester to record the number of arrester actions. It applies to 220KV and below arresters. It has same using ambient conditions as the arrester. It’s not for serious contaminated and violent vibration place.
