變壓器變比測試儀用(yong)途(tu)描(miao)述：

變壓器變比測試儀以單片機為核(he)心進行測量計算和自(zi)動(dong)控制,全中文菜單操作界面，具(ju)有(you)顯示直觀、穩定性好(hao)、精度高、測量范(fan)圍寬且(qie)現場(chang)不需三(san)相電源等(deng)優點(dian)。

可以測量(liang)各種三相變(bian)壓器的變(bian)比和(he)接線組別，同時(shi)也能(neng)測量(liang)單相變(bian)壓器和(he)電壓互感器的變(bian)化和(he)極性，而且能(neng)顯示變(bian)比誤差，具有數據打印功能(neng)。

詳細(xi)說明：

該測(ce)試儀為(wei)解(jie)決(jue)用(yong)(yong)變(bian)比電橋測(ce)量變(bian)壓器(qi)的(de)(de)(de)變(bian)比，操作過程繁瑣，測(ce)量范圍狹(xia)窄、已經(jing)不(bu)適應現(xian)代測(ce)量的(de)(de)(de)快節奏、高效(xiao)率的(de)(de)(de)要求。為(wei)此，我公司采用(yong)(yong)現(xian)代電子(zi)技術、研制(zhi)出新代變(bian)比組別測(ce)試儀。具有體積小，重量輕，精度高，性能(neng)穩定，菜單操作，界面(mian)友好。對(dui)各(ge)種(zhong)變(bian)壓器(qi)的(de)(de)(de)變(bian)比/組別可次性測(ce)完。
