Utility poles have a grounded wire. Is this just for lightening? Is not connected the neither one of the 3 phase wires, is it? Is the static electricity wire always present, and is it grounded (at every pole, or every x poles)? What does the multi-grounded neutral wire do, and has it always have to be present? The 3 phase wires are only grounded at destination when electricity is being consumed? If domestic consumers receive just one phase current, why there are 3 wires coming from the pole to the house? Is ground always the return path for electrons? Is there a ground connection at every house directly or at the nearest utility pole? In power plants the wires in the generator are connected to the ground, to close the circle?
