Surge Counter, Feature : Reliability Of Operation

Surge Counter will automatically recordthe number of lightning and switching surge discharges of Station class surge arresters on a five digit cyclometer dial. Impulse discharges through the arrester must also pass through the surge counter as 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 will register impulse discharges through the arrester of an amplitude of 40 amperes or greater.
