1.1 Nature of the crown effect

SCROLL TO TOP

1.1.1 Electronic avalanche

The corona effect refers to all the phenomena associated with the appearance of gas conductivity in the environment of a conductor subjected to high voltage.

This conductivity is due to the phenomenon of ionization, which can be explained as follows:

There are always a certain number of positive ion - free electron pairs in the air, created by cosmic radiation or natural radioactivity....
