韓國(guó)AUTOMA,AD160-400BF 價(jià)格低! 三相不平衡的原因主要有：電壓波動(dòng)、電壓過(guò)低會(huì)造成三相電壓不平衡；單相負(fù)荷過(guò)大即三相負(fù)載不平衡會(huì)造成三相電流不平衡；相與相之間短路、相與零線(xiàn)短路都會(huì)引起三相電壓、電流不平衡。三相電流不平衡度計(jì)算方法一般有以下常用的兩個(gè)公式?！ ∮泄β拾聪率接?jì)算：一種功率表對(duì)于正弦電路，下式成立：上式中，U、I分別為正弦交流電的有效值，φ為電壓與電流信號(hào)的相位差。在超高頻和微波頻段，有TEM波和非TEM波之分。在TEM波的同軸系統(tǒng)中，電壓和電流雖有確切含意，但測(cè)量其絕對(duì)值很困難。
