An earthed wire is run above the HV 3-phase and does a good job of
providing a low impedance path for lighting. One side of the HV to LV
transformer is earthed as well as the center tap of the secondary
(Neutral). The neutral is again earthed at the service entrance as is
one
end of the green wire running unimpeded to every human touchable
conductor.

Is something flowing in the all earth wires?

If you actually knew anything about electricity, which you don't, you
would know that under normal circumstances there is no current in the
earth ground connection.

In Poland under normal circumstances always is the electrons net flow into
the ground.

The earth ground connection is for safety and current will only flow if
something is wrong.

Where is such situation?

This is also why radios powered by AC are connected to earth ground; it is
for safety against electrocution if something in the equipment breaks and
has NOTHING to do with the operation of the radio as a radio.

In Poland in the all power AC lines is an exccess of electrons.
The ground is necessary.

The details are such that more electrons is gain in one half of the cycle
than jump off in the second.

What the things are in your country?
