i have a 480v primary delta - 240v secondry delta transformer and i am getting 120v to ground on all phases on secondary side and 240v phase to phase. i thought i should get 208v to ground on b phase.
there is no neutral, xo, x4. the voltage is not exactly 120v. anyway to measure voltage to find high leg
so what is the voltage present on each leg individually
i am pretty sure the secondary is not grounded.
it feeds all three phase equipment. so with all this info i would assume that i will not need to identify b phase with orange tape
