諧波(bo)電(dian)流(liu)、電(dian)壓波(bo)動(dong)和閃爍

產品概述：

諧波電流(liu)、電壓(ya)(ya)波動和閃爍測試主要測量EUT工作(zuo)時注入到電網(wang)(wang)中的(de)諧波及 EUT引起的(de)電網(wang)(wang)電壓(ya)(ya)的(de)變(bian)化(hua)。電壓(ya)(ya)波動指標反映(ying)了(le)(le)突然的(de)較大的(de)電壓(ya)(ya)變(bian)化(hua)程度(du)，而(er)閃爍指標則反映(ying)了(le)(le)一段時間內連續的(de)電壓(ya)(ya)變(bian)化(hua)情況(kuang)。

· 產品說明

　　由于電(dian)(dian)(dian)(dian)子產(chan)品內(nei)部大量使(shi)用(yong)開關電(dian)(dian)(dian)(dian)源，非線性的電(dian)(dian)(dian)(dian)能轉(zhuan)化，會(hui)向電(dian)(dian)(dian)(dian)網(wang)里注入(ru)大量諧波(bo)電(dian)(dian)(dian)(dian)流，可能引起(qi)電(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)壓波(bo)形畸變，過零噪聲、斷(duan)路器誤動作等(deng)不(bu)良(liang)現象。此(ci)外，一些頻繁自動通斷(duan)的設備，會(hui)引起(qi)電(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)壓產(chan)生波(bo)動，導致(zhi)同一電(dian)(dian)(dian)(dian)網(wang)的照(zhao)明設備出(chu)現閃爍，引起(qi)人體不(bu)適。
　　諧(xie)(xie)波測量(liang)主要(yao)測量(liang)EUT工作時注入到電網的諧(xie)(xie)波。
　　電壓波(bo)動和閃爍測(ce)量主要測(ce)量EUT引起的電網電壓變化(hua)。
