Surge Counter Used in Substation Lightning Surge Protection Device
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.
