SAT70手持式電(dian)機故障測試(shi)儀(yi)特點(dian)定時關(guan)機，低(di)(di)功(gong)耗設(she)計，大容量充電(dian)電(dian)池，自動低(di)(di)電(dian)壓充電(dian)提(ti)示(shi)；重量輕，攜(xie)帶方便。

LD1083/HAD便攜(xie)型電(dian)(dian)機(ji)故障(zhang)測(ce)試(shi)(shi)儀 4.測(ce)試(shi)(shi)功能：短路(lu)測(ce)試(shi)(shi)(電(dian)(dian)機(ji)、繞(rao)阻、線圈(quan)的匝間、線間)相角測(ce)試(shi)(shi)、對地絕緣測(ce)試(shi)(shi)、交(jiao)流(liu)電(dian)(dian)機(ji)三相平(ping)衡測(ce)試(shi)(shi)與轉、子故障(zhang)、直流(liu)電(dian)(dian)機(ji)繞(rao)阻與電(dian)(dian)杻污染

SMHG-6800系列電(dian)(dian)機(ji)故障(zhang)測(ce)試(shi)儀應用了“I/F”法(fa)技術，即：對于純感性線(xian)圈，電(dian)(dian)源(yuan)電(dian)(dian)壓U不變(bian)的條件下，電(dian)(dian)源(yuan)頻(pin)率(lv)（F）加倍，電(dian)(dian)流（I）將減半；通過(guo)這一方(fang)法(fa)可以快速、準確地(di)判斷(duan)電(dian)(dian)機(ji)繞組品質及各相間平衡情(qing)況。同時兼(jian)有對地(di)絕緣測(ce)量、功(gong)率(lv)因數角(jiao)、電(dian)(dian)容測(ce)試(shi)等(deng)功(gong)能，又可以通過(guo)電(dian)(dian)纜線(xian)進行遠距離測(ce)量，從(cong)而對電(dian)(dian)機(ji)進行綜合測(ce)試(shi)，從(cong)根本上解決了目前在電(dian)(dian)機(ji)故障(zhang)判斷(duan)上的猜測(ce)行為(wei)。
