上海韓施電氣提醒大家，使用電動機保護器時必須注意控制線路的接線問題，以確保正常運行。一旦線路異常了也不要擔心，可以通過以下幾種方法排除：
1、試送投運法
主要查找剩余電動機保護器自身故障。
具體操作方法是：先切斷，再將剩余電動機保護器的零序負荷側引線全部拆除（二級、三級剩余電流動作保護器直接將出線拆除）再合保護器。若保護器仍然無法投運，則說明保護器自身故障，應予以修理或更換。
若能正常運行，則保護器本身并*，再查找配電盤或者線路。其操作方法是：先將各路出線或交流負荷切斷，若不能運行則說明配電盤上有故障，應檢查各路、儀表等設備是否絕緣良好，接線是否正確；若能正常運行則說明配電盤上*。當確認故障發(fā)生在外線路上時，可采用分線查找法查找故障點。
2、直觀巡查法
就是巡視人員針對故障現(xiàn)象進行分析判斷，對保護區(qū)域包括剩余電動機保護器和被保護的線路設備等進行直觀巡視，從而找出故障點。巡視時應著重對線路的轉角、分支、交叉跨越等復雜地段和故障點進行檢查。這種方法簡便易行，適用于對明顯故障點的查找。如導線斷線落地、拉線與導線接觸及錯誤接線等。
3、數(shù)值比較法
就是借助對線路或設備進行測量，并把所測的數(shù)值與原數(shù)值進行比較，從而查出故障點。需要特別指出的是：當線路中性線絕緣下降或設備中性線重復接地，容易引起保護頻繁跳閘，而二級保護器不跳閘。在解決二級保護器跳閘時，不應采取將相線與中性線對調(diào)的方法投運二級保護，將設備重復接地線拆除即可。
4、分線排除法
上海韓施電氣建議排查線路故障點時，可以按照“先主干、再分支、后末端"的順序，斷開低壓電網(wǎng)的各條分支線路，僅對主干線進行試送電，若主干線*，那么主干線便能正常運行。然后，再依次將分支和末端投入運行。哪條線路投入運行時電動機保護器跳閘，故障點就在哪條線路上，就可在此線路上集中查找故障點。
