Power stations use ground return. when we constructed power stations in my
electrical years, we dug extensive trenches filled with copper conductors
to provide the widest earthing system.
In a three phase system, only the differential current returns to the
power station. That means that there is
Mark and all,
Thank you for some very useful replies. You confirmed my understanding.
You know how a customer can be so sure of (usually) himself...
Mark, I don't care that much about the structure of the utility. But
it's this customer's understanding of utility structure that got me the

A 120/240 V split phase system is supplied by a
center tapped 240 V transformer. The center tap
is grounded, deriving the neutral. Unbalanced
current from the two hot phase conductors return back through the neutral.
