電能質量不合格(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電能質量標準規(guī)定的指標。不合格的電能質量有時還表現為功率因數低，無功損耗大或供電可靠性差等。

西門子斷路器3WL的增強型測量功能模塊F05能夠測量配電系統(tǒng)的29次諧波，同時，還具有瞬態(tài)波形記錄功能。通過諧波測量，不但能夠分析電網質量，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象。和斷路器3VL通信的SEMEAS P表同樣具有21諧波測量功能。圖6為SEMEAS P表測量的諧波顯示。功率因數的監(jiān)測管理，有助于在不同的區(qū)域自動或者手動投切電容器組，提高功率因數。因此，通過現場設備的諧波測量以及瞬態(tài)波形記錄，在控制中心能夠對這些測量值以及事件進行系統(tǒng)地分析，有利于發(fā)現電網中存在的問題以及采取相應的措施，來提高電能質量和用電水平。
