NAGM Series adjustable high-voltage  digital megger   NAGM可調(diào)高壓數(shù)字兆歐表

產(chǎn)品簡介

NAGM系列可調(diào)高壓數(shù)字兆歐表測試電壓高，功率大，被測量對(duì)象往往又帶有工頻泄漏或感應(yīng)上高壓干擾電能，因此為了人身安全，使用該儀器首先一定要接好安全接地線。

該儀表在高壓啟動(dòng)后，請(qǐng)不要采用人工放電方式檢查儀表，在測試完畢后也應(yīng)等待儀表自動(dòng)放電使電壓表回零后才進(jìn)行例行安全需要的人工放電。因?yàn)槎搪贩烹姷膹?qiáng)烈電脈沖波有損被測對(duì)象的絕緣壽命，如果脈沖竄入儀表，也有損儀表內(nèi)的集成電路。

NAGM系列可調(diào)高壓數(shù)字兆歐表是為了解決高壓變電站、發(fā)電廠現(xiàn)場強(qiáng)干擾下對(duì)大型高壓變壓器、電機(jī)電器、遠(yuǎn)程電力電纜或埋設(shè)電纜等電氣絕緣電阻特性的測試而設(shè)計(jì)研制。它亦可用于廣泛領(lǐng)域的電氣絕緣電阻特性測量。
