目前，我國(guo)配(pei)電(dian)(dian)(dian)(dian)系統的(de)(de)(de)電(dian)(dian)(dian)(dian)源中性點一(yi)般是(shi)(shi)不直接(jie)接(jie)地的(de)(de)(de)，所以當(dang)線路單相接(jie)地時(shi)流(liu)(liu)過(guo)故(gu)障(zhang)點的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)實際(ji)是(shi)(shi)線路對(dui)地電(dian)(dian)(dian)(dian)容產(chan)生的(de)(de)(de)電(dian)(dian)(dian)(dian)容電(dian)(dian)(dian)(dian)流(liu)(liu)。據統計，配(pei)電(dian)(dian)(dian)(dian)網(wang)的(de)(de)(de)故(gu)障(zhang)很大(da)(da)程度是(shi)(shi)由于(yu)線路單相接(jie)地時(shi)電(dian)(dian)(dian)(dian)容過(guo)大(da)(da)而(er)無法自行(xing)息弧引起的(de)(de)(de)。因(yin)(yin)此，我國(guo)的(de)(de)(de)電(dian)(dian)(dian)(dian)力規程規定(ding)當(dang)10kV和(he)35kV系統電(dian)(dian)(dian)(dian)容電(dian)(dian)(dian)(dian)流(liu)(liu)分別大(da)(da)于(yu)30A和(he)10A時(shi)，應裝設消弧線圈以補償電(dian)(dian)(dian)(dian)容電(dian)(dian)(dian)(dian)流(liu)(liu)，這就要求對(dui)配(pei)網(wang)的(de)(de)(de)電(dian)(dian)(dian)(dian)容電(dian)(dian)(dian)(dian)流(liu)(liu)進行(xing)測量(liang)后(hou)做決定(ding)。另外，配(pei)電(dian)(dian)(dian)(dian)網(wang)的(de)(de)(de)對(dui)地電(dian)(dian)(dian)(dian)容和(he)PT的(de)(de)(de)參(can)數配(pei)合(he)會產(chan)生PT鐵磁諧(xie)(xie)振過(guo)電(dian)(dian)(dian)(dian)壓。為(wei)了驗(yan)證該配(pei)電(dian)(dian)(dian)(dian)系統是(shi)(shi)否會發生PT諧(xie)(xie)振及發生什么性質的(de)(de)(de)諧(xie)(xie)振，也必須(xu)準確測量(liang)配(pei)電(dian)(dian)(dian)(dian)網(wang)的(de)(de)(de)對(dui)地電(dian)(dian)(dian)(dian)容值。傳統的(de)(de)(de)測量(liang)配(pei)網(wang)電(dian)(dian)(dian)(dian)容電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)方(fang)法有單相金屬接(jie)地的(de)(de)(de)直接(jie)法、外加電(dian)(dian)(dian)(dian)容間接(jie)測量(liang)法等(deng)，這些方(fang)法都要接(jie)觸到一(yi)次設備，因(yin)(yin)而(er)存在試驗(yan)危險、操(cao)作(zuo)繁雜，工作(zuo)效率低等(deng)缺點。

JY6701電容電流測試儀功能特點：

● 直接從PT的二次側(ce)測(ce)量配電網的電容電流，無需和一次側(ce)打交(jiao)道
● 不存在試驗的(de)(de)危險性，無需做繁(fan)雜的(de)(de)安全(quan)措(cuo)施和等待冗長的(de)(de)調度命(ming)令
● 只需將測量線接(jie)于(yu)PT的開口三角端就可以測量出電(dian)容電(dian)流的數(shu)據
● PT開口(kou)三角處注(zhu)入的微弱異頻測試信號，不會對繼電(dian)保(bao)護和PT本(ben)身產生任何影響，也避開了50Hz的工頻干擾信號
● 輸(shu)出端(duan)可以耐(nai)受100V的交流電壓，測量時系(xi)統有單(dan)相接地故障發生，亦(yi)不會(hui)損壞PT和測試儀(yi)
● 無需做特別的安(an)全措施，使(shi)這項工作變得安(an)全、簡單、快捷，且(qie)測試結果準(zhun)確、穩定、可靠
