Your answer?

When you lie you can always make your point.
I never agreed you were right about any of this.
Two phase simply does not work like this

I clearly said *I believe* you said that it would be two phase. But it's
hard to keep track, because you won't answer a simple series of questions,
instead you bail out, claiming you can't answer a simple question about
whether a phase still exists when I change the angle from 90 to some other
choice, because "that system doesn't exist". So much for electrical
engineering, now it's claimed that we can only analyze that which is
actually deployed. That would get expensive fast.

So feel free to give us your definitive answer to the above simple question.
Here it is again, go step by step:

According to Fretwell, two phase power existed 100 years ago, and it
was over two wires, 90 degrees phase difference. Suppose I run it
over 3 wires instead, with a shared neutral, make it 120V from each
phase to the neutral. So, you have a generator supplying 120V on
each of two windings on the same shaft 90 deg phase difference,
one shared neutral. Would there still be two phases there?


So now, I run that from the generator into a house, we have three wires,
shared neutral, 120V, two phases, 90 deg phase difference, correct?
I could hook a scope up to the neutral and see two phases, 90 deg
apart, correct?

If I change the phase difference to 179 degrees instead of 90
by rotating one coil, are there still two phases? Yes or no?


Now I rotate it to 180 phase difference. Are there still two phases,
yes or no? If you disagree, explain how it's different, how there
suddenly there are not two phases there, where one phase just went.


(My answer is yes and the final step above makes it absolutely IDENTICAL
to what you have coming into the house with 240/120. The electrons
are behaving exactly the same. )
