我國電(dian)(dian)力系統實行兩(liang)部制電(dian)(dian)價：除了(le)收取(qu)(qu)計量(liang)裝置所計量(liang)的(de)(de)費用外，還(huan)要(yao)根據(ju)變(bian)壓(ya)(ya)(ya)器(qi)(qi)容(rong)量(liang)收取(qu)(qu)基本電(dian)(dian)費；對于較大(da)用戶在投運(yun)變(bian)壓(ya)(ya)(ya)器(qi)(qi)時(shi)還(huan)要(yao)一次**納增容(rong)費。隨著電(dian)(dian)力行業的(de)(de)發展，用電(dian)(dian)量(liang)的(de)(de)增大(da)，自有變(bian)壓(ya)(ya)(ya)器(qi)(qi)和個人承包變(bian)壓(ya)(ya)(ya)器(qi)(qi)已漸(jian)(jian)漸(jian)(jian)占據(ju)了(le)配變(bian)中相當的(de)(de)份(fen)額，隨之而來的(de)(de)就是(shi)個人為了(le)達(da)(da)到少交費、多(duo)用電(dian)(dian)的(de)(de)目的(de)(de)而采取(qu)(qu)的(de)(de)各(ge)種弄虛作假的(de)(de)手(shou)段（主要(yao)是(shi)改、換(huan)變(bian)壓(ya)(ya)(ya)器(qi)(qi)銘牌）；有些用戶年電(dian)(dian)費額達(da)(da)數(shu)十萬之多(duo)，電(dian)(dian)力部門苦于沒有有效的(de)(de)控制手(shou)段。
