線纜錢(qian)(qian)路(lu)(lu)能比于(yu)一種電(dian)(dian)解(jie)電(dian)(dian)金屬罐(guan)，限電(dian)(dian)后(hou)錢(qian)(qian)路(lu)(lu)還(huan)出現(xian)(xian)剩的電(dian)(dian)荷量，對(dui)地(di)還(huan)在繼續有(you)電(dian)(dian)極電(dian)(dian)位差。若限電(dian)(dian)后(hou)及時驗電(dian)(dian)，驗電(dian)(dian)筆會現(xian)(xian)示出錢(qian)(qian)路(lu)(lu)有(you)電(dian)(dian)。于(yu)是(shi)需路(lu)(lu)經加以尖端(duan)放電(dian)(dian)，驗電(dian)(dian)無(wu)電(dian)(dian)后(hou)，才(cai)行安(an)裝重復接地(di)線。
