Why do the voltage vectors rotate 180 deg. when the ground is moved from the neutral to say phase 2. This is for wye connected phases??? Can't seem to wrap my head around this one. Thanks.

7another4,

I also can't figure out your angles.

My convention was to have VBC' be the voltage from C' to B. You seem to have opposite convention which explains some angles. I have referenced horizontal as 0°. You have AB1 at 0°. You have everything tilted 30° compared to Slavag's sketch.

I am sorry, Slava, as I was in a hurry I omitted to thank you for your kindly reference.
Jghrist, thanks again for your remarks.
Best Regards
