Multilin Phasor Questions

Multilin Phasor Questions

Multilin Phasor Questions

(OP)
I am trying to figure out why the phasor doesn't look right. The PT is connected in an open-delta configuration. The voltage seems right on all 3 phases. Vab and Vca stay at the same angle while Vbc bounces all over the place. It looks like Vca is 180 degrees out of phase. Would this mean that the PT is wired wrong? Any help would be much appreciated.

Thanks!

Ryan

RE: Multilin Phasor Questions

IIRC, VB and Neutral need to be tied together and grounded. I would double check the wiring diagram in the 369 manual.
