HI All
I cannot understand the physics of why a neutral that is ungrounded will be at a higher voltage relative to a live on a single phase transformer lets say a 11kV to 230 V trf . not centre tapped as opposed to when the neutral is grounded
i need to see some diagrams and calcalutions from 1st principles please
it is troubling me
regards
