The Attempt at a Solution The first one is what I measured in a lab. The second one my prediction if the phase reversed,base on the first one is it reasonable?

There will be no voltage difference between Point O and the neutral lead providing all is perfectly balanced. When O is not connected to neutral you have a floating star-point.
