we all know that corona is nothing but ionization of air around
the conductor and there by allowing current to pass through
ionized air.but we are not getting any short circuit in between
the respective phases though the air turned as a conductive media
between them??
Answer Posted / raghavendran
In corona, the air around the conductor(phase) is ionized
and starts conducting.But the potential build up between any
two conductors is not higher than the break down strength of
insulation of air.The clearance between the two conductors
is designed keeping this fact is mind.Hence it do not get
short circuited.May be if the clearance is small, there
might be any possibility of Short circuit.
