在我們電工日常工作當中，面對三相五線電路接地供電網絡時，不時會遇到零線帶電現象！此故障現象不但嚴重危害用戶人身，還存在停電檢修耽誤正常生活生產用電的問題，為此頗令我們電工從業者頭痛！

      其實對于這種零線帶電故障所產生的原因，總結歸納起來不外乎以下五種可能：

      一、用電線路中的用電設備的確存在絕緣破損引發的漏電故障，而由于各種原因漏電保護裝置未動作，造成此種情況發生；

      二、電網中有一相發生接地故障，可是由于線路當中的保護裝置因動作整定值不當或者機構失靈等原因而拒動，也會出現這種情況；

      三、電路當中的零線發生斷裂現象，并且斷裂點后面的個別電器有漏電現象或者存在三相用電負荷不平衡的情況，同樣會引發零線帶電故障；

      四、變壓器低壓側工作接地線同接地裝置連接處，如果存在接觸不良、氧化銹蝕等情況致使接地電阻超過規定值時，也極易導致出現零線帶電問題；

      五、在高低壓線路并存時，高壓電網通過磁場感應或者靜電感應竄入低壓回路，同樣會誘發該故障現象出現。
