上海0.2S級三相多功能電表485通訊是按IEC標準設計，與同步的(de)網(wang)(wang)絡(luo)電力儀表(biao)。具有全電量(liang)測量(liang)，電能(neng)統計，電能(neng)質(zhi)量(liang)分析(xi)及網(wang)(wang)絡(luo)通(tong)訊(xun)等功能(neng)，主要用(yong)于對(dui)電網(wang)(wang)供電質(zhi)量(liang)的(de)綜合監控。該系列儀表(biao)采 用(yong)了模塊(kuai)(kuai)(kuai)化設計，配合功能(neng)豐富(fu)的(de)外部 DI/DO 模塊(kuai)(kuai)(kuai)、AI/AO 模塊(kuai)(kuai)(kuai)、Micro SD 卡(TF 卡)事(shi)件記錄(SOE)模塊(kuai)(kuai)(kuai)、網(wang)(wang)絡(luo)通(tong)訊(xun)模塊(kuai)(kuai)(kuai)、溫(wen)濕度測溫(wen)模塊(kuai)(kuai)(kuai)，

報警說明： 儀表帶兩組報警，每組報警可以檢測多種報警條件，包括電參量開關量輸入變化、相損、逆相序、不平 衡度、諧波等。其中開關量輸入變化和逆相序只需設置使能位，其余報警需要設定報警條件， 報警類型簡介： 1.電參量報警 過流：零值報警設置不適用于過流報警，當單相電流高于或等于動作值且滿足設定的動作延時時間， 報警大類: 過流報警 報警小類： A相過流報警 報警使能
