Is the stator three phase line voltage the same ? and is it current zero 定子三相電壓是否相等?其電流是否為零?
Triple - phase line 三相平衡線
Zero - phase lines 零相位線
Skilfully use single - phase electric energy meter check - up device examine three - phase line four meritorious electric energy meter 巧用單相電能表校驗(yàn)裝置檢三相四線有功電能表
The three - phase circuit that has balanced three - phase sources , balanced ( equal ) three - phase loads and balanced three - phase line - impedances is called a balanced three - phase system 一個(gè)具有對稱三相電源,對稱三相負(fù)載和對稱三相線路阻抗的三相電路被稱為三相對稱電路。
