²  计量功效：撑持(chi)正向、反(fan)(fan)向有功电能(neng)计量，此(ci)中(zhong)反(fan)(fan)向🀅电量计入(ru)正向电量；

²  费(fei)控形式转(zhuan)换功(gong)(gong)效：电能(neng)表(biao)备(bei)长途(tu)预(yu)支(zhi)费(fei)和本地预(yu)支(zhi)费(fei)功(gong)(gong)效，两种形式能(neng🦹)够按照办(ban)理须(xu)要随时转(zhuan)换；

²  充(chong)值(zhi)功效：电(dian)表在🌠(zai)本地预支费(fei)形(xing)式时(shi)，用(yong)户(hu)必须先充(chong)值(zhi)后(hou)用(yong)电(dian)，主(zhu)动(dong)结算(suan)计费(fei)、扣费(fei)，无(wu)费(fei)断电(dian)，  用(yong)户(hu)充(chong)值(zhi🎉)冲(chong)正余额(e)后(hou)电(dian)表主(zhu)动(dong)合闸供电(dian)；

²  退费功效：当用户(hu)搬迁时(shi)，如(ru)电🔜(dian)表(biao)🧸内(nei)仍(reng)有(you)余(yu)额(e)，能够将预缴金(jin)额(e)退还用户(hu)，而(er)后将电(dian)表(biao)余(yu)额(e)主(zhu)动“归(gui)零”；

²  换(huan)表(biao)(biao)(biao)功效：当某一个电表(biao)(biao)(biao꧑)产(chan)生毛病须要改换(huan)时，可共同体系完成换(huan)表(biao)(biao)(biao)功效，记实🎶旧表(biao)(biao)(biao)底数(shu)(shu)和新表(biao)(biao)(biao)底数(shu)(shu)并主(zhu)动结(jie)算旧表(biao)(biao)(biao)数(shu)(shu)据和用度；

²  长(zhang)途监控与通断电(dian)(dian)：能长(zhang)途及时监测各(ge)装备的运转(zhuan)状态， 长(zhang)途节制通断电(dian)(🅺dian)，可经由过(guo)程电(dian)(dian)脑下(xia)发(fa)号令对某一个或某一些(xie)房间停止通断电(dian)(dian)节制。

²  恶(e)性(x🐷ing)负载限定：电能表可主动辨(bian)认恶(e)性(xing)负载，💞呈(cheng)现恶(e)性(xing)负载（大功率用电装备）后主动拉闸(zha)断电，保证(zheng)用电宁静(jing)；

²  总功率(lv)限定：电(dian)能(neng)表可完成总功率(lv)限定，当(dang)负(fu)荷(he)跨越(yue)设定的最大功率(lv)阀值时，电(dian)表主(z🌺hu)动(dong)跳闸，保证用电(dian)宁(ning)静；

²  保电(dian)(dian)(dian)功(gong)效：电(dian)(dian)(dian)能表具备保电(dian)(dian)(dian)功(gong)效，当(dang)保电(dian)(dian)(dian)功(gong)效启用后，不(bu)管何种情况(kuan𒐪g)下电(dian)(dian)(dian)表都不(bu)会跳闸断(duan)电(dian)(dian)(dian)，供特别(bie)办理情况(kuang)下利用；
