（一）智能建筑

商業(ye)大樓和(he)高(gao)層(ceng)住宅(zhai)配電(dian)中(zhong)，現代電(dian)力電(dian)子設(she)備（可調(diao)速馬達，空調(diao)，在線UPS，開關電(dian)源，彩電(dian)，激(ji)光打印機等）為非線性負(fu)荷(he)，雖然(ran)負(fu)荷(he)沖(chong)擊性小，但所產生的諧波電(dian)流非常嚴重(zhong)。

（二） 電弧爐

電(dian)(dian)弧爐作為非線性及沖擊負荷(he)接入(ru)電(dian)(dian)網。導致(zhi)電(dian)(dian)網嚴(yan)重三相不平衡，產生負序電(dian)(dian)流；產生高次(ci)諧波(bo)，普遍存在偶次(ci)諧波(bo)與(yu)奇次(ci)諧波(bo)共存的(de)(de)狀況，使(shi)電(dian)(dian)壓畸(ji)變(bian)更趨復雜化；存在嚴(yan)重的(de)(de)電(dian)(dian)壓閃變(bian)；功率因數低。

（三） 中頻爐

中頻(pin)爐(lu)在工(gong)作(zuo)時(shi)所產生的(de)奇次諧波電流(liu)嚴重。

（四）交直流傳動電(dian)機(ji)和(he)軋機(ji)

電(dian)(dian)網電(dian)(dian)壓(ya)波動，功(gong)率因數降低，產(chan)生(sheng)奇次諧波，使電(dian)(dian)網電(dian)(dian)壓(ya)畸變。

（五）電焊機群

電(dian)焊(han)機(ji)為單相負(fu)荷(he)時，3次諧波電(dian)流大、波形(xing)畸變(bian)嚴(yan)重，三(san)相電(dian)流極不平衡(heng)，電(dian)壓(ya)閃變(bian)嚴(yan)重。
