設備的(de)節電(dian)(dian)(dian)(dian)原理(li)，來自于因為原本從供電(dian)(dian)(dian)(dian)回路進到工(gong)廠的(de)用電(dian)(dian)(dian)(dian)，已(yi)經存在包(bao)括電(dian)(dian)(dian)(dian)力諧波(bo)的(de)污染、以及(ji)三相電(dian)(dian)(dian)(dian)壓偏(pian)高(gao)或偏(pian)低、三相電(dian)(dian)(dian)(dian)壓、電(dian)(dian)(dian)(dian)流相位之間(jian)(jian)的(de)不平衡、以及(ji)因為負載特性引(yin)起的(de)電(dian)(dian)(dian)(dian)壓與電(dian)(dian)(dian)(dian)流間(jian)(jian)的(de)相位差…等。

而在供電過程中產生電力質量的污染，引起的電能損耗。 所以安裝這一套PQCS系統就是為了改善上述的電力質量污染，及對電力質量進行優化。也就是說，讓客戶的供電損耗，盡量減少到最低，來達到節電的效果。

通過PQCS電(dian)力品質優化系統的18段(duan)自(zi)動(dong)調(diao)整電(dian)壓穩(wen)壓功能(neng)，將額(e)定電(dian)壓供給負載(zai)端，吸(xi)收負載(zai)于(yu)電(dian)源中之雜波(bo)(bo)/諧(xie)波(bo)(bo)，借(jie)以消(xiao)除因雜波(bo)(bo)而導(dao)致之浪費(fei)。運用(yong)電(dian)磁(ci)(ci)平衡(heng)(heng)原理，平衡(heng)(heng)激(ji)磁(ci)(ci)突(tu)波(bo)(bo)，以維持電(dian)機能(neng)平順無偏差的運轉(zhuan)，進而提(ti)升(sheng)機械(xie)效率并減少浪費(fei)。
