    任何電網(wǎng)設(shè)備都存在對(duì)地絕緣電阻和接地電流監(jiān)控的必要性，為保證其安全運(yùn)行，這種監(jiān)控必須是連續(xù)不斷或經(jīng)常的，并要在接地電流大于允許值時(shí)，就能發(fā)出警報(bào)以提醒操作者妥善處理由于絕緣電阻下降而可能引發(fā)的事故。
   All power network equipment have the necessity to monitor the ground insulation resistance and the ground current to ensure the running safely. This monitoring must be continuously or frequently, and when the ground current is higher than allowable, it can give alarms to remind the operator to deal with the fault to avoid the possible accident due to insulation resistance decreased.
   SD-0.66-L型剩余(零序)電流互感器,與本公司專(zhuān)用電流繼電器配套使用。該產(chǎn)品為戶內(nèi)電纜式，具有結(jié)構(gòu)新、體積小、精度高、外形美觀等特點(diǎn)。主要適用于TT或TN系統(tǒng)中ABCN同時(shí)穿越ZCT時(shí)使用
    SD-0.66-L type residual (zero sequence) current transformer is used together with our specified current protection relay. It is designed for in-house cable e***y and has the features of modern construction, small size, high precision and fine appearance.
It is mainly applied for ABCN to go through the ZCT simultaneously in the TT and TN system.

    由SD-ZLD系列剩余電流動(dòng)作保護(hù)繼電器和零序電流互感器組合，構(gòu)成接地故障保護(hù)裝置，適用于TN、TT和IT電網(wǎng)系統(tǒng)。通過(guò)接地電流互感器檢測(cè)出接地零序漏電電流，經(jīng)剩余電流動(dòng)作保護(hù)繼電器與設(shè)定值的比較和判別，及時(shí)發(fā)出動(dòng)作信號(hào)，接通或斷開(kāi)報(bào)警回路，以避免事故的擴(kuò)大，從而保證人員及設(shè)備的安全。
