I have read answers pertaining to this same question, but I could not understanf why the phase voltage is equal to line voltage. This answer says:
In a delta system, the two points required to measure a line voltage also happen to be the same two points connected across the phase.
What I don't understand is why aren't the rest two phases affecting this voltage since they both are connected to one point each and are out of phase. What am I failing to see?
I think I have not been able to express what my confusion is. I do understand since the points across which phase voltage is measured is also the point the lines are connected and I do agree with that, but if I compare the voltage for a delta configuration and other for an isolated AC supply I get the same values for the voltage. I don't understand why.
