I know that if I have a 3-Phase wye connected load with only 3 wires and no neutral then as long as each leg is balanced, current will be balanced on all three legs and the neutral point will be 0V. However if the phases become unbalanced then isnt' it true that without a neutral to return unbalanced current, the neutral point will elevate to something higher then 0V to ground?
When this happens and neutral point is elevated above ground, then is it possible that the L-N voltages across each load on each of the phases would be something other than 120V? Would all the L-N voltaegs be the same still or could they all vary? In other words, could I have 3 different voltages that weren't 120V for the L-N connection on this 3 phase wye load?
