Lightning Arrestor Discharge Counter Arrestor Counter
The Surge Counter JS-8 is connected under the arrester in serial, it isused for recording the operating times of arrester. JS-8 type is allied for 6KV -220KV arrester. The environment condition shall meet the requirement of the arrester, for example, the altititude doesn't exceed 4000m, the environment temperature is -40 Centigrade, the counter can't be put in the place that includes gas eroding metal and insulation parts, serious pollution and drastic vibration.
The Discharging Counter is made up of valve element, silicon bridge type rectifier, capacitor, electromagnestic counter etc. It makes use of the arrester energy (surge current and power frequency current) of fetch the voltage on valve element (non linear resistance), then it charges to the capacitor in single direction through silicon bridge type rectifier, makes the coils of electromagneric counter discharge with form of DC power to move the counter, thus it can realize that the operating times can be recorded.
