電(dian)壓(ya)波動的危(wei)害：IT設備：當電(dian)壓(ya)波動超(chao)過40％，持續時(shi)間超(chao)過12個周波(0.24s)時(shi)，導致數據丟失。

數控(kong)設備：當電壓(ya)低(di)于10%額定電壓(ya)、持續時間(jian)超過2～3個周波時，可能導致保(bao)護(hu)性停(ting)機(ji)。

閃變的危害：連(lian)接(jie)在系統中的精密設備無(wu)法正常工作。

諧波超標的危(wei)害

設(she)備過熱、中性線(xian)電(dian)流大(da)、斷(duan)路器誤動作；
功率因數下降，損耗增(zeng)加，電費(fei)增(zeng)加；
供電波形產生(sheng)畸(ji)變，精(jing)密設備工作異(yi)常；
可能導(dao)致并聯補償電(dian)容器鼓肚、爆裂(lie)；
測試計(ji)量器(qi)具顯示不準；
干(gan)擾(rao)通信系統。

功(gong)(gong)率因數低(di)的(de)危害：功(gong)(gong)率因數低(di)意味著負荷電(dian)流(liu)要(yao)遠大于(yu)系統只提供有功(gong)(gong)功(gong)(gong)率時的(de)電(dian)流(liu)值，用(yong)戶不僅(jin)要(yao)承(cheng)擔增加輸電(dian)線路、配電(dian)變壓器和電(dian)纜容(rong)量(liang)的(de)成本(ben)，還要(yao)支付由此增加的(de)損耗費用(yong)。

三相(xiang)不(bu)平(ping)衡(heng)的危(wei)害：三相(xiang)不(bu)平(ping)衡(heng)引起的系統故(gu)障日益嚴重。特別是對于交流電弧爐、單(dan)相(xiang)供電的電氣化(hua)鐵道牽(qian)引機車(che)等大容量的不(bu)平(ping)衡(heng)負(fu)荷，其負(fu)序問題更為突出(chu)。
