主要用(yong)(yong)于交流線(xian)路35～500kV的帶(dai)電(dian)(dian)(dian)測量過線(xian)塔的絕(jue)緣(yuan)子(zi)串電(dian)(dian)(dian)壓(ya)(ya)分(fen)布值。也(ye)可用(yong)(yong)于試驗室內(nei)各種35kV以及交流電(dian)(dian)(dian)壓(ya)(ya)絕(jue)緣(yuan)子(zi)的電(dian)(dian)(dian)壓(ya)(ya)分(fen)布測量。是(shi)一種理想的保障線(xian)路運行安(an)全(quan)的檢測儀表和帶(dai)電(dian)(dian)(dian)作業輔助工具。 采用(yong)(yong)靜電(dian)(dian)(dian)式結構，測量絕(jue)緣(yuan)子(zi)兩點之間電(dian)(dian)(dian)位差(cha)，將被測電(dian)(dian)(dian)壓(ya)(ya)變成電(dian)(dian)(dian)場進(jin)行測量。因(yin)而阻抗(kang)高，對于被測量系統的影響Z小。被測出的信號經內(nei)部放(fang)大處理，Z后(hou)以電(dian)(dian)(dian)壓(ya)(ya)值的形式，由LCD數字顯示輸出。因(yin)此測量時(shi)操作迅速，簡單明了。
