As a normal in the all country is leakage. Corona is from time to time.

"Physics, Electricity . the loss of all or part of a useful agent, as of
the electric current that flows through an insulator"

In overhead power supply the air is an insulator.

The both (corona and leakage) are nonsymmetric in AC.
So the ground is the only remedy.

Hello Szczepan.
Neither you nor I would want to be near any "leaky" insulator.

Air is the "leaky" insulator.
I was many times under the 400kV line and I am still alive.
Is it dangerous in UK.

You probably do not know the difference leakage/breakdown.

You appear
not to understand the definition and meaning of "insulator". Your past
behaviour indicates that there is no point in trying to explain it to you.
All I will suggest is that you try to acquire and read a textbook on the
subject.

Textbooks are for children.
