交流側雙向電能計量電表CPA認證是按IEC標準(zhun)設計，與(yu)同步的網(wang)絡(luo)電力儀(yi)表。具(ju)有(you)全電量測(ce)量，電能(neng)統計，電能(neng)質量分析及網(wang)絡(luo)通訊等功(gong)能(neng)，主要用(yong)于對(dui)電網(wang)供(gong)電質量的綜合(he)監(jian)控。該系列儀(yi)表采(cai) 用(yong)了模塊(kuai)(kuai)化設計，配(pei)合(he)功(gong)能(neng)豐富的外部 DI/DO 模塊(kuai)(kuai)、AI/AO 模塊(kuai)(kuai)、Micro SD 卡(TF 卡)事件記(ji)錄(SOE)模塊(kuai)(kuai)、網(wang)絡(luo)通訊模塊(kuai)(kuai)、溫濕度(du)測(ce)溫模塊(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
