3 phase voltges to neutral in a delta circuit

Reply Tue 12 Jul, 2016 01:54 pm
In a 3 phase delta system A, B and C are the three lines and a neutral. B-line is the 208v or the high/wild leg while the other two are 120 v all measured to neutral. When you measure across line-A to line-C, C to B and A to B you get 240v. Why do you get 240v and not get 328 volts from B to neutral?

Kor it has to do with phase relationships. Doubtless we'll get a more detailed explanation. Incidentally your first sentence doesn't make sense

I apologize, I was rushed. I was trying to explain it to a friend when I realized that the math would overwhelm him. I just told him "God made it that way to annoy you".

I apologize
Me too Kor, I hate math
Thanks to Tim for the diagram

Kor, like I mentioned, it's a phasing thing, they don't peak simultaneously
