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.
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. 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.

Hello chaps. I've solved the puzzle of the what S* is. He's an out-of-work
comedy writer.
He says that in Poland they have a power supply that
operates with corona discharge as normal (I assume into the house) and
operates with lightning strikes as the norm.
Of most interest to us all will be S*'s assertion that physics varied from
country to country before WWII. Anyone know (or care to guess) who unified
physics around the world?
It's dull and drizzling here in my part of the UK. That posting from S* made
me smile so it did have a positive use (pun intended).

73 to all, Ian.
