The JSY series discharge counter is suitable for various types of silicon carbide and zinc oxide lightning arresters with voltage levels of 330KV and below, and is used under the same environmental conditions as the connected lightning arrester. This series of products adopts high-power zinc oxide valve plates, which have the characteristics of large flow capacity, wide adaptability to voltage levels, accurate and reliable action counting, and high sensitivity to lower limit action current. The JSY-8 discharge counter is a single pointer ten digit cyclic counting indicator; The JSY-8S model adopts a patented product dual pointer electromagnetic counter that has obtained national invention patents for counting indication. It has a counting carry function and can continuously count 100 times before entering the next counting cycle. It is suitable for use in areas with frequent lightning arrester actions and unmanned places. The JSY series discharge counter is enclosed in a transparent heat-resistant glass cover.

The JSY series discharge counter is suitable for the following environmental conditions: 1. Altitude not exceeding 2000 meters; 2. The ambient temperature ranges from -40 ℃ to+50 ℃; 3. Not suitable for gas environments with severe corrosion of metals and insulation components, as well as places with severe pollution and severe vibration.

All performance indicators of the discharge counter product comply with the national machinery industry standard JB2440-91 "Discharge Counter for Lightning Arresters".
