GD681B三相(xiang)電(dian)(dian)(dian)(dian)能(neng)(neng)質量(liang)(liang)(liang)分(fen)析(xi)(xi)儀功能(neng)(neng)簡介：隨著我國國民經濟的(de)蓬(peng)勃發展，用(yong)電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)的(de)逐年增多，電(dian)(dian)(dian)(dian)力(li)負(fu)荷(he)(he)急劇加大(da)，*不同性(xing)(xing)質的(de)用(yong)電(dian)(dian)(dian)(dian)負(fu)荷(he)(he)（特(te)別是沖擊(ji)性(xing)(xing)和(he)非(fei)線性(xing)(xing)負(fu)荷(he)(he)容(rong)量(liang)(liang)(liang)）的(de)不斷增長，對(dui)電(dian)(dian)(dian)(dian)網的(de)電(dian)(dian)(dian)(dian)能(neng)(neng)供(gong)電(dian)(dian)(dian)(dian)質量(liang)(liang)(liang)造(zao)成了(le)很大(da)的(de)影響，突(tu)出(chu)表現為電(dian)(dian)(dian)(dian)網諧波(bo)含量(liang)(liang)(liang)增大(da)、波(bo)形畸變嚴重、電(dian)(dian)(dian)(dian)壓波(bo)動與(yu)閃變和(he)三相(xiang)不平衡超出(chu)允許范圍(wei)等電(dian)(dian)(dian)(dian)能(neng)(neng)質量(liang)(liang)(liang)相(xiang)關問題。為了(le)解(jie)決以(yi)(yi)上的(de)問題，首(shou)先(xian)要能(neng)(neng)對(dui)以(yi)(yi)上現象(xiang)進行(xing)準(zhun)確的(de)測量(liang)(liang)(liang)與(yu)分(fen)析(xi)(xi)，基于這樣的(de)需求適時(shi)開發研制出(chu)電(dian)(dian)(dian)(dian)能(neng)(neng)質...
