目前，電(dian)能(neng)(neng)(neng)表(biao)的形(xing)式及功(gong)(gong)(gong)能(neng)(neng)(neng)是多(duo)樣化的，各大生產廠家(jia)在(zai)型(xing)號上面命名(ming)也有區(qu)別，常規有功(gong)(gong)(gong)電(dian)能(neng)(neng)(neng)表(biao)示其(qi)功(gong)(gong)(gong)能(neng)(neng)(neng)和用途只用兩(liang)個字(zi)母。其(qi)它(ta)有特殊(shu)功(gong)(gong)(gong)能(neng)(neng)(neng)電(dian)子式電(dian)能(neng)(neng)(neng)表(biao)表(biao)示其(qi)功(gong)(gong)(gong)能(neng)(neng)(neng)和用途多(duo)用三(san)個字(zi)母。

電(dian)(dian)表的型號(hao)(hao)一(yi)般(ban)從(cong)類(lei)(lei)別代(dai)號(hao)(hao)，組(zu)別代(dai)號(hao)(hao)，功(gong)(gong)(gong)能(neng)(neng)代(dai)號(hao)(hao)，設(she)計序(xu)號(hao)(hao)等進行編寫(xie)。一(yi)般(ban)的電(dian)(dian)能(neng)(neng)表類(lei)(lei)別代(dai)號(hao)(hao)均為D。組(zu)別代(dai)號(hao)(hao)通常分(fen)為：A（安培小時計）、B（標準）、D（單相電(dian)(dian)能(neng)(neng)表）、F（伏特小時計）、J（直流）、S（三相三線）、T（三相四線）、X（無功(gong)(gong)(gong)）。功(gong)(gong)(gong)能(neng)(neng)代(dai)號(hao)(hao)通常分(fen)為：F（分(fen)時計費）、S（電(dian)(dian)子式(shi)）、Y（預(yu)付費式(shi)）、D（多(duo)功(gong)(gong)(gong)能(neng)(neng)）、M（脈沖(chong)式(shi)）、Z（最大需量）。設(she)計序(xu)號(hao)(hao)為數字(zi)。
