"There is no phase angle difference between two ends of the same wire, even if there is impedance in the wire. "
I have no clue what you mean by this. I said
take phase A and B and connect a load between. This is not the same wire. There is a 120 degree phase angle between them.
Read the last post again. Take a look at this site http://home.comcast.net/~ronaldrc/site1138/55.htm . It shows the phases as they are.
