Thankyou very much for all the help, I’m sure there’s lots more to learn but I do feel like I understand the answer to the question I initially asked.Yes the voltage (tension) is only on the live side as it were. The pulling and pushing distance moved was the current. Both ends of the rope move the same. The current in L and N are the same.
yes
Yes. The ground is a conductor, so your imaginary cable is 'real', but with some resistance (sorry thats probably a complication!)
I think I follow, yes. I find it easier to think in terms of current flow - just call it current - rather than worrying about electrons pushing or pulling.
Yes
So that all being said the phase conductor comes from the transformer to the installation and the neutral goes back to the transformer to the centre.
Back at the transformer on the opposite side of the windings we have the side of the transformer which goes back to the generator. (Let’s keep it simple and say there is only generator - transformer - installation). On the generator side of the transformer or back at the generator. What is the determining factor as to why it’s the tips of the star connection where our phase wire connects that carry the voltage ?
I would have expected back at an AC generator for a single phase to be connected in the generator at 180 degrees ?
What I’m asking is back at the generator which side is our voltage being produced on to then attach to the phase cables ?
I feel the answer is because of the neutral introduction, or to do with the way delta and star are connected ?
