JS series discharge counters are suitable for various types of zinc oxide arresters with voltage levels of 330 kV or below, and the environmental conditions for use are the same as those of the connected arresters. This series of products adopt high-temperature silicon carbide valve plates, which have the characteristics of large circulation capacity, wide range of adaptive voltage levels and accurate and reliable action counting. JS-8 discharge counter is a single-pointer ten-digit cycle counting indicator; JS-8S is a double-pointer 100-digit cycle counting indicator, which has counting carry function, and can count 100 times continuously before entering the next cycle counting period, so it is suitable for areas with frequent lightning arrester actions and unattended places.
