Answer Posted / k.c. bankar
When a high voltage transmitted in a
transmission line, due to magnetic effect on the core of
the conductor all most all electrons passes on the surface
of the conductor.And When dielectric voltage becomes more
than 30v\cm . So the air outside the conductor surface
becames conducive and looks bluish and due to dielectric
breakdown of air a hissing noise comes from surrounding,
Called as corona !
Due to corona OZONE formation on the outside surface of the
conductor. The effect of this to the power system is called
as corona effect.
