请问高手们，一个三角形/星形接法的变压器问题
三角形接法的的一次侧，他的0电位怎么来设置，例如这一段程序：et,4,circu124,5 !Stranded Coil element(To FEM domain)
et,5,circu124,2 !capcitor
et,6,circu124,4,1 !Independent Current Source(low)
et,7,circu124,4,1 !Independent Current Source(high)
et,13,circu124,0 !连线电阻
r,4,1 !Symmetry factor for stranded coil
r,5,1/25981.58/2/3.1415/400 !电容值
r,6,,84.75,400,,-120, !Independent volu Source(lowA)幅值和相位353.6
r,7,,84.75,400,,0, !Independent volu Source(lowB)幅值和相位
r,8,,84.75,400,,+120, !Independent volu Source(lowC)幅值和相位
r,9,,36722,400,,-120, !Independent volu Source(highA)幅值和相位
r,10,,36722,400,,0, !Independent volu Source(highB)幅值和相位
r,11,,36722,400,,+120, !Independent volu Source(highC)幅值和相位
r,13,1e-10 !连线电阻

我不知道怎么来定我的0电位，
我也不知道，在ansys里每个回路里必须要有一个束缚电压自由度，是么？
