礦山井下不接地系統絕緣監測裝置采用低(di)頻(pin)脈沖方波注(zhu)入法可(ke)以可(ke)靠地(di)(di)、準確(que)地(di)(di)監視交流、直流、交直流混合IT 系(xi)統 （不接地(di)(di)系(xi)統）對地(di)(di)的(de)(de)絕(jue)緣(yuan)阻值。由于各(ge)種 應(ying)用、系(xi)統類型、操作條件、變速驅(qu)動(dong)器的(de)(de)應(ying)用，高系(xi)統泄漏(lou)電(dian)容等，測量(liang)(liang)技(ji)術必須(xu)能夠滿足(zu)不同的(de)(de)要(yao)求，以確(que)保優(you)化響應(ying)時間和相對不確(que)定(ding)性(xing)。可(ke)以從設置菜(cai)單(dan)中選擇的(de)(de)不同的(de)(de)測量(liang)(liang)條件，允許對特殊應(ying)用測量(liang)(liang)技(ji)術的(de)(de)優(you)化適應(ying)。

在(zai)操作期間(jian)，絕緣(yuan)監視儀(yi)不間(jian)斷(duan)地監視整(zheng)個(ge)IT 系(xi)(xi)(xi)(xi)統(tong)(tong)的(de)(de)(de)絕緣(yuan)阻(zu)值(zhi)(zhi)，當(dang)該值(zhi)(zhi)低于預先設定的(de)(de)(de)響應(ying)值(zhi)(zhi)時(shi)，時(shi)觸發報警。必(bi)須把設備連接在(zai)IT系(xi)(xi)(xi)(xi)統(tong)(tong)（不接地系(xi)(xi)(xi)(xi)統(tong)(tong)）和PE 線之間(jian)才(cai)能得到測量值(zhi)(zhi)。通過微控制器來記錄和測量疊加在(zai)系(xi)(xi)(xi)(xi)統(tong)(tong)上(shang)的(de)(de)(de)uA范圍的(de)(de)(de)測量值(zhi)(zhi)。響應(ying)測量時(shi)間(jian)取決于的(de)(de)(de)測量要(yao)求，系(xi)(xi)(xi)(xi)統(tong)(tong)泄露電容，絕緣(yuan)電阻(zu)和可能的(de)(de)(de)系(xi)(xi)(xi)(xi)統(tong)(tong)相(xiang)關(guan)的(de)(de)(de)干擾。
