電纜故障測試儀是迎合工業級電力行業方案和IT時代的快速發展,將原來電纜故障測試儀的局限性，用工控嵌入式計算機平臺系統、網絡服務業務、USB通信技術系統化，極大提高了電纜故障測試儀的使用功能和利用價值以及便捷的現場環境操作。電纜故障測試儀系統測試由系統主機和故障定位儀以及電纜路徑儀三部分組成，電纜故障測試儀用于電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)(lan)(lan)各(ge)類故障(zhang)的(de)測試，電(dian)(dian)(dian)纜(lan)(lan)(lan)路(lu)徑、電(dian)(dian)(dian)纜(lan)(lan)(lan)埋設深(shen)度(du)的(de)尋測和電(dian)(dian)(dian)纜(lan)(lan)(lan)檔(dang)案資料的(de)日常維護管理，以及同軸(zhou)通信(xin)電(dian)(dian)(dian)纜(lan)(lan)(lan)和市話電(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)開路(lu)、短路(lu)故障(zhang)的(de)*測試。
電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)故障(zhang)測(ce)試儀使用(yong)于測(ce)量(liang)各種不同截面、不同介質(zhi)的(de)各種電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、高(gao)頻同軸電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)，市話(hua)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)及(ji)(ji)兩根(gen)以(yi)上(shang)均勻鋪設的(de)地埋(mai)電(dian)(dian)(dian)(dian)線等電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)高(gao)低阻、短路、開路、斷線以(yi)及(ji)(ji)高(gao)阻泄漏(lou)和高(gao)阻閃路性故障(zhang)。
（a）電(dian)力(li)電(dian)發(fa)生(sheng)故障(zhang)的原因(yin)。a機械損(sun)傷，電(dian)纜(lan)直接受(shou)外力(li)損(sun)傷，如振動、熱脹冷縮(suo)等引起(qi)鉛護套損(sun)壞(huai)等；b絕(jue)緣(yuan)受(shou)潮，因(yin)終端(duan)頭或(huo)連接盒施(shi)工(gong)不(bu)當使(shi)水分侵(qin)入；c絕(jue)緣(yuan)老化；d護層(ceng)腐蝕；e過(guo)(guo)壓、雷擊(ji)或(huo)其他過(guo)(guo)壓使(shi)電(dian)纜(lan)擊(ji)穿(chuan)；f過(guo)(guo)熱，過(guo)(guo)載(zai)或(huo)散熱不(bu)良，使(shi)電(dian)纜(lan)絕(jue)緣(yuan)擊(ji)穿(chuan)；g材(cai)料(liao)本身缺(que)陷。
