380伏三(san)(san)相四線電(dian)(dian)(dian)(dian)(dian)路中，任意兩(liang)根火(huo)線之(zhi)間的電(dian)(dian)(dian)(dian)(dian)壓都是(shi)380伏，任意一根火(huo)線與零線之(zhi)間都可以(yi)組成220伏。這個系(xi)統可以(yi)形成三(san)(san)種(zhong)電(dian)(dian)(dian)(dian)(dian)源：即單(dan)相220伏電(dian)(dian)(dian)(dian)(dian)源，單(dan)相380伏電(dian)(dian)(dian)(dian)(dian)源，三(san)(san)相380伏電(dian)(dian)(dian)(dian)(dian)源，第 I 種(zhong)家用比(bi)較多(duo)，第三(san)(san)種(zhong)工廠里電(dian)(dian)(dian)(dian)(dian)機(ji)類用得(de)多(duo)，第二(er)種(zhong)用得(de)少，只有交流電(dian)(dian)(dian)(dian)(dian)焊機(ji)經常(chang)用到單(dan)相380伏電(dian)(dian)(dian)(dian)(dian)源。
