What is a Surge Counter?
A surge counter is a device that is connected to a surge arrester and registers impulse discharges through the arrester of an amplitude of 40 amperes or greater. It is insulated from, and mounted at the base of the arrester, and connected between the arrester ground terminal and the station ground. The counter continuously measures any change of leakage and can record the discharging times of the surge arrester itself.
