產品(pin)詳(xiang)細介(jie)紹

、產品概述：

 HZDL-421全(quan)自動電容電流測試儀，直(zhi)接(jie)從PT的(de)二次側測量(liang)配電網的(de)電容(rong)電流(liu)，與傳(chuan)統的(de)測試方法相比，該全自動電容(rong)電流(liu)測試儀無需和(he)一次側打交道(dao)，因而不(bu)存在試驗的(de)危(wei)險性(xing)，無需做繁雜的(de)安全措施(shi)和(he)等待冗長的(de)調度命(ming)令，只需將(jiang)測量(liang)線接于PT的開口(kou)三角端就可以測量出(chu)電容電流的數據。由于(yu)從PT開口三角處注入(ru)的(de)是微弱的(de)異頻(pin)測試信號，所以既不會對繼(ji)電保護和(he)PT本(ben)身產(chan)生任何影(ying)響，又避開了(le)50Hz的工頻干擾信號，同時(shi)測試儀的輸出端可以耐(nai)受100V的交流(liu)電壓(ya)，若測量(liang)時(shi)系(xi)統有(you)單(dan)相接地故(gu)障發(fa)生，亦(yi)不會(hui)損壞PT和(he)測試儀(yi)，因而無需做特別的安(an)全措施，使這(zhe)項工作變得(de)安(an)全、簡單、快捷，且(qie)測試結果準(zhun)確、穩定、可靠(kao)。
