²  计量(l𓆉i𓃲ang)功(gong)(gong)效(xiao)：撑持正(zheng)向(xiang)、反向(xiang)有功(gong)(gong)电(dian)能计量(liang)，此中(zhong)反向(xiang)电(dian)量(liang)计入正(zheng)向(xiang)电(dian)量(liang)；

²  费控形(xing)式(shi)转ღ换功(gong)效：电能表(biao)备长途预(yu)支(zhi)费和本(ben)地(di)预(yu)支(zhi)费功(gong)效，两ﷺ种形(xing)式(shi)能够按照办(ban)理(li)须要随时转换；

²  充值功效(♈xiao)：电表在本地预支费(fei)(fei)(fei)形式时，用户(hu)(hu)必须先🤡充值后用电，主动(dong)(dong)结算计费(fei)(fei)(fei)、扣费(fei)(fei)(fei)，无费(fei)(fei)(fei)断电，  用户(hu)(hu)充值冲正余额后电表主动(dong)(dong)合闸供电；

²  退费功效：当用(yong)户搬(ban)迁(qi💫an)时，如电表内仍不足额(e)，能够将(jiang)(jiang)预(yu)缴金额(e)退还(🐷hai)用(yong)户，而后将(jiang)(jiang)电表余额(e)主动“归(gui)零”；

²  换表(biao)功效：当某一(yi)🌠个电表(biao)产生(sheng)毛病须要改换时(shi)，可共同体系完成换表(biao)功效，记实(shi)旧(jiu)表(biao)底数(shu)和新表(biao)底数(shu)并(ꦺbing)主(zhu)动结算旧(jiu)表(biao)数(shu)据(ju)和用(yong)度；

²  长(zhang)途(tu)监控与通断(duan)(duan)电：能长(zhang)途(tu)及时(shi)监测各装备的运转状(zhuang)态， 长(zhanꦍg)途(tu)节(jieꦍ)制通断(duan)(duan)电，可经由过程电脑下发号(hao)令对某(mou)一个或(huo)某(mou)一些(xie)房间停止(zhi)通断(duan)(duan)电节(jie)制。

²  恶(e)性负载限定：电(dian)(dian)能表可主(zhu)动辨认恶(e)性负载，呈现恶(e)性负载（大功率用电(dian)𓆏(dian)装备）后主(zhu)动拉闸断电(dian)(dian)，保证(zheng)用电(dian)(dian)宁静；

²  总(zong)功(gong)率(lv)限定：电能(neng)表(biao)可൩完成总(zong)功(gong)率(lv)限定，当负荷跨越设定的最(zui)大功(gong)率(lv)阀值时，电表(biao)主动跳闸，保证用电宁(ning)静；

²  保(bao)电(dian)(dian)(dian)功(gong)效：电(dian)(dian)(dian)能表(biao)具备保(bao)电(dian)(dian)(dian)功(gong)效，当保(bao)电(dian)(dian)(dian)功(gong)效启(qi)用后(hou)，不管何种情(qing)况下电(dian)(dian)(dian)表(biao)都不会(hui)跳闸断电(dian)(dian)(dian)，供特别(bie)办(ban)理情(qing)况♋下利用；
