電能質(zhì)量不合格(或不符合要求)通常指供電電壓的幅值變化，波形畸變和頻率偏移等超過(guò)電能質(zhì)量標(biāo)準(zhǔn)規(guī)定的指標(biāo),。不合格的電能質(zhì)量有時(shí)還表現(xiàn)為功率因數(shù)低,，無(wú)功損耗大或供電可靠性差等。

西門(mén)子斷路器3WL的增強(qiáng)型測(cè)量功能模塊F05能夠測(cè)量配電系統(tǒng)的29次諧波,，同時(shí)，還具有瞬態(tài)波形記錄功能,。通過(guò)諧波測(cè)量,，不但能夠分析電網(wǎng)質(zhì)量，而且還可能找到故障失常的原因,，以便于減少或者消除失?，F(xiàn)象。和斷路器3VL通信的SEMEAS P表同樣具有21諧波測(cè)量功能,。圖6為SEMEAS P表測(cè)量的諧波顯示,。功率因數(shù)的監(jiān)測(cè)管理，有助于在不同的區(qū)域自動(dòng)或者手動(dòng)投切電容器組,，提高功率因數(shù),。因此，通過(guò)現(xiàn)場(chǎng)設(shè)備的諧波測(cè)量以及瞬態(tài)波形記錄,，在控制中心能夠?qū)@些測(cè)量值以及事件進(jìn)行系統(tǒng)地分析,，有利于發(fā)現(xiàn)電網(wǎng)中存在的問(wèn)題以及采取相應(yīng)的措施，來(lái)提高電能質(zhì)量和用電水平,。
