、等電位連接檢測原理
  電位差平衡原理
  等電位連接是將建築物內的金屬物體（如電氣設備外殼、金屬管道等）與yu防fang雷lei裝zhuang置zhi進jin行xing電dian氣qi連lian接jie
，使shi它ta們men處chu於yu相xiang同tong的de電dian位wei，避bi免mian雷lei電dian產chan生sheng的de電dian位wei差cha對dui設she備bei和he人ren員yuan造zao成cheng危wei害hai。檢jian測ce基ji於yu電dian位wei差cha測ce量liang原yuan理li，使shi用yong電dian位wei差cha測ce試shi儀yi，測ce量liang等deng電dian位wei連lian接jie點dian之zhi間jian以yi及ji等deng電dian位wei連lian接jie點dian與yu接jie地di裝zhuang置zhi之zhi間jian的de電dian位wei差cha。
  當電位差在安全範圍內（接近零伏特）時，說明等電位連接良好
；若電位差過大，則存在安全隱患
，需要檢查連接線路是否導通、連接點是否牢固。
  電氣連續性檢測
  等電位連接的電氣連續性是保證其有效性的關鍵。檢測運用導通電阻測量原理，通過導通測試儀測量等電位連接線路的電阻值。
  導(dao)通(tong)電(dian)阻(zu)值(zhi)應(ying)足(zu)夠(gou)小(xiao)
