簡要描述：

HDGC3551多(duo)功能用(yong)(yong)電(dian)(dian)(dian)檢(jian)(jian)查(cha)儀在(zai)不停電(dian)(dian)(dian)及不驚擾用(yong)(yong)戶(hu)的(de)(de)情況下，對三(san)相三(san)線(xian)(xian)及三(san)相四(si)線(xian)(xian)電(dian)(dian)(dian)力(li)系統500kV及以下各種接(jie)線(xian)(xian)方式的(de)(de)電(dian)(dian)(dian)能計量(liang)(liang)(liang)裝(zhuang)置及表計的(de)(de)計量(liang)(liang)(liang)誤差進行檢(jian)(jian)測(ce)(ce)(ce)，以檢(jian)(jian)測(ce)(ce)(ce)高低(di)壓計量(liang)(liang)(liang)裝(zhuang)置及表計誤差是否超標，檢(jian)(jian)查(cha)各類技術(shu)性、隱蔽性竊電(dian)(dian)(dian)。可以檢(jian)(jian)測(ce)(ce)(ce)電(dian)(dian)(dian)壓、電(dian)(dian)(dian)流基波(bo)(bo)及2～25次諧(xie)波(bo)(bo)。適用(yong)(yong)于用(yong)(yong)電(dian)(dian)(dian)檢(jian)(jian)查(cha)、電(dian)(dian)(dian)力(li)工程竣工檢(jian)(jian)驗、線(xian)(xian)損檢(jian)(jian)測(ce)(ce)(ce)、各類電(dian)(dian)(dian)量(liang)(liang)(liang)異(yi)常分(fen)析、諧(xie)波(bo)(bo)超標檢(jian)(jian)測(ce)(ce)(ce)及分(fen)析。
