1、可測量(liang)(liang)變(bian)(bian)壓(ya)(ya)器(qi)的(de)(de)(de)空(kong)載電(dian)(dian)(dian)流(liu)、空(kong)載損耗、短(duan)路(lu)電(dian)(dian)(dian)壓(ya)(ya)、短(duan)路(lu)（負(fu)載）損耗。 2、可進(jin)行(xing)諧波(bo)試驗(yan)(yan)，分析至31次諧波(bo)。 3、儀(yi)器(qi)內部(bu)自(zi)動進(jin)行(xing)量(liang)(liang)程切換，允許測量(liang)(liang)電(dian)(dian)(dian)壓(ya)(ya)、電(dian)(dian)(dian)流(liu)范圍寬(kuan)，接線簡單。 4、做(zuo)三(san)相(xiang)變(bian)(bian)壓(ya)(ya)器(qi)的(de)(de)(de)空(kong)載、負(fu)載試驗(yan)(yan)時，儀(yi)器(qi)能自(zi)動判斷接線是否正確，并(bing)顯示三(san)相(xiang)電(dian)(dian)(dian)壓(ya)(ya)、電(dian)(dian)(dian)流(liu)的(de)(de)(de)向(xiang)量(liang)(liang)圖。 5、單機(ji)可以(yi)完成1000KVA以(yi)下的(de)(de)(de)配(pei)電(dian)(dian)(dian)變(bian)(bian)壓(ya)(ya)器(qi)全電(dian)(dian)(dian)流(liu)下的(de)(de)(de)負(fu)載實驗(yan)(yan)；在三(san)分之一額定電(dian)(dian)(dian)流(liu)下可完成3150KVA以(yi)下的(de)(de)(de)配(pei)電(dian)(dian)(dian)變(bian)(bian)壓(ya)(ya)器(qi)的(de)(de)(de)負(fu)載

我國(guo)電(dian)(dian)力(li)(li)系統實(shi)行兩部制電(dian)(dian)價：除了(le)收取計(ji)量裝置所計(ji)量的(de)費(fei)用(yong)(yong)(yong)(yong)外，還(huan)要根(gen)據變(bian)(bian)壓器(qi)(qi)容(rong)(rong)量收取基本(ben)電(dian)(dian)費(fei)；對于較大(da)(da)用(yong)(yong)(yong)(yong)戶在(zai)投運(yun)變(bian)(bian)壓器(qi)(qi)時(shi)還(huan)要一次(ci)交納增容(rong)(rong)費(fei)。隨著電(dian)(dian)力(li)(li)行業的(de)發展，用(yong)(yong)(yong)(yong)電(dian)(dian)量的(de)增大(da)(da)，自有變(bian)(bian)壓器(qi)(qi)和私人(ren)(ren)承包變(bian)(bian)壓器(qi)(qi)已(yi)漸漸占據了(le)配變(bian)(bian)中相當的(de)份額，隨之而來的(de)就是個人(ren)(ren)為(wei)了(le)達到少交費(fei)、多(duo)用(yong)(yong)(yong)(yong)電(dian)(dian)的(de)目(mu)的(de)而采取的(de)各種弄虛作假的(de)手段（主要是改、換變(bian)(bian)壓器(qi)(qi)銘(ming)牌(pai)）；有些用(yong)(yong)(yong)(yong)戶年偷(tou)電(dian)(dian)費(fei)額達數十萬(wan)之多(duo)，電(dian)(dian)力(li)(li)部門苦于沒有有效的(de)控制手段。
