                                                                                                                                                                                                                              在測接地電阻時,有些因素造成接地電阻不準確:

                                                                                                                                                                                                                              (1)地網周邊土壤構成不一致,地質不一,緊密、干濕程度不一樣,具有分散性,地表面雜散電流、特別是架空地線、地下水管、電纜外皮等等,對測試影響特別大。解決的方法:取不同的點進行測量,取平均值。

                                                                                                                                                                                                                              (2)測試線方向不對,距離不夠長。解決的方法:找準測試方向和距離。

                                                                                                                                                                                                                              (3)輔助接地極電阻過大。解決的方法:在地樁處潑水或使用降阻劑降低電流極的接地電阻。
