功率(lv)因(yin)數(shu)的大小與(yu)電(dian)(dian)路(lu)的負(fu)荷性質有關，功率(lv)因(yin)數(shu)低，說明電(dian)(dian)路(lu)用于交變(bian)磁場轉換的無功功率(lv)大，從(cong)而降(jiang)低了設(she)備的利用率(lv)，增加了線路(lu)供電(dian)(dian)損失。
所(suo)以，供電部(bu)門對用電單位的功(gong)率因數有一定(ding)的標準要(yao)求。
④減少(shao)(shao)了用戶(hu)的(de)電(dian)(dian)費支出；透過上述各元件損失的(de)減少(shao)(shao)及功率因數提高(gao)的(de)電(dian)(dian)費優惠。
此外，有(you)些電(dian)(dian)力電(dian)(dian)子設備如整流器(qi)、變(bian)頻器(qi)、開關電(dian)(dian)源(yuan)(yuan)等(deng)(deng)；可飽和設備如變(bian)壓(ya)器(qi)、電(dian)(dian)動機(ji)、發電(dian)(dian)機(ji)等(deng)(deng)；電(dian)(dian)弧設備及電(dian)(dian)光源(yuan)(yuan)設備如電(dian)(dian)弧爐、日(ri)光燈等(deng)(deng)，這些設備均(jun)是(shi)主(zhu)要的(de)諧波(bo)(bo)源(yuan)(yuan)，運行時將產(chan)生(sheng)大量的(de)諧波(bo)(bo)。諧波(bo)(bo)對發動機(ji)、變(bian)壓(ya)器(qi)、電(dian)(dian)動機(ji)、電(dian)(dian)容(rong)器(qi)等(deng)(deng)所(suo)有(you)連接于電(dian)(dian)網的(de)電(dian)(dian)器(qi)設備都有(you)大小不(bu)等(deng)(deng)的(de)危(wei)害(hai)，主(zhu)要表現為產(chan)生(sheng)諧波(bo)(bo)附(fu)加損耗(hao)，使得設備過(guo)載過(guo)熱以(yi)及諧波(bo)(bo)過(guo)電(dian)(dian)壓(ya)加速設備的(de)絕緣老化等(deng)(deng)。
并聯到線路上(shang)進行無功補償(chang)的(de)電(dian)(dian)(dian)容(rong)器對諧(xie)波(bo)(bo)會有(you)放大作用，使(shi)得系統電(dian)(dian)(dian)壓(ya)及(ji)電(dian)(dian)(dian)流(liu)的(de)畸變更加(jia)嚴重。另外，諧(xie)波(bo)(bo)電(dian)(dian)(dian)流(liu)疊加(jia)在電(dian)(dian)(dian)容(rong)器的(de)基(ji)波(bo)(bo)電(dian)(dian)(dian)流(liu)上(shang)，會使(shi)電(dian)(dian)(dian)容(rong)器的(de)電(dian)(dian)(dian)流(liu)有(you)效值增(zeng)加(jia)，造(zao)成溫度升(sheng)高(gao)，減少電(dian)(dian)(dian)容(rong)器的(de)使(shi)用壽命。
諧波電(dian)流使變壓器的銅損耗(hao)增加(jia)，引(yin)起局部過熱、振動、噪音(yin)增大、繞組(zu)附加(jia)發熱等(deng)。
諧(xie)波(bo)污(wu)染(ran)(ran)也會增(zeng)加電纜等輸電線(xian)路(lu)的損耗。而(er)且諧(xie)波(bo)污(wu)染(ran)(ran)對(dui)通訊(xun)質量(liang)有(you)影(ying)響。當電流諧(xie)波(bo)分量(liang)較高(gao)時，可能會引起繼電保護的過(guo)電壓保護、過(guo)電流保護的誤(wu)動(dong)作。因此，如果系統量測出諧波含量過高時，選擇希拓旗下有源濾波器是不錯的解決方法。
