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.

I did something you are incapable of doing; I looked up the electrical
distribution system in Poland.

The distribution system in Poland is the same as the rest of Europe
and conforms to IEC 60446, which means, you babbling idiot, there is
no current in the ground connection unless there is a fault.

Yes. The leakages are also unsymmetric:
"Coronas may be positive or negative. This is determined by the polarity of
the voltage on the highly-curved electrode. If the curved electrode is
positive with respect to the flat electrode we say we have a positive
corona, if negative we say we have a negative corona. (See below for more
details.) The physics of positive and negative coronas are strikingly
different. This asymmetry is a result of the great difference in mass
between electrons and positively charged ions, with only the electron having
the ability to undergo a significant degree of ionising inelastic collision
at common temperatures and pressures."

In a power lines are also the counterpoise:
"Overhead power lines are often equipped with a ground conductor (shield
wire or overhead earth wire). A ground conductor is a conductor that is
usually grounded (earthed) at the top of the supporting structure to
minimize the likelihood of direct lightning strikes to the phase conductors.
The ground wire is also a parallel path with the earth for fault currents in
earthed neutral circuits. Very high-voltage transmission lines may have two
ground conductors."

The only difference between country are the textbooks.
You should know that before the IIWW in the Soviet Union, Germany and US
were quite different phisics.
Now are the same in the whole "free" world but the older books are also
avaiable.
