我國電(dian)(dian)(dian)力(li)系(xi)統實行兩部制(zhi)電(dian)(dian)(dian)價(jia)：除了(le)收取(qu)計(ji)量(liang)(liang)裝置(zhi)所(suo)計(ji)量(liang)(liang)的(de)(de)費(fei)(fei)(fei)用(yong)(yong)外(wai)，還要根據變(bian)壓器(qi)(qi)容(rong)量(liang)(liang)收取(qu)基本電(dian)(dian)(dian)費(fei)(fei)(fei)；對(dui)于較大用(yong)(yong)戶在投(tou)運(yun)變(bian)壓器(qi)(qi)時還要一次**納增(zeng)容(rong)費(fei)(fei)(fei)。隨(sui)著(zhu)電(dian)(dian)(dian)力(li)行業的(de)(de)發展，用(yong)(yong)電(dian)(dian)(dian)量(liang)(liang)的(de)(de)增(zeng)大，自(zi)有變(bian)壓器(qi)(qi)和個(ge)人承包變(bian)壓器(qi)(qi)已漸漸占據了(le)配變(bian)中相當的(de)(de)份(fen)額(e)，隨(sui)之而(er)來的(de)(de)就是(shi)個(ge)人為(wei)了(le)達(da)到(dao)少交費(fei)(fei)(fei)、多(duo)用(yong)(yong)電(dian)(dian)(dian)的(de)(de)目的(de)(de)而(er)采取(qu)的(de)(de)各種弄(nong)虛作(zuo)假的(de)(de)手(shou)段（主要是(shi)改、換變(bian)壓器(qi)(qi)銘(ming)牌）；有些用(yong)(yong)戶年電(dian)(dian)(dian)費(fei)(fei)(fei)額(e)達(da)數十(shi)萬之多(duo)，電(dian)(dian)(dian)力(li)部門苦于沒有有效(xiao)的(de)(de)控制(zhi)手(shou)段。
