what is corona effect?

Answer Posted / daher

it generally occure at high voltage overhead transmission
lines,when the dielectric voltage becomes more than
30v/cm.the the surrounded air becomes ionized meaning
conductive and hissing noise issued due to the saturated
air by electronic, and a violet color could be seen.their
are some advantages of this phenomena we can get,one of
theme in cold region while the ice accumulate over the T.L
the heat that emitted due to the accident of electronic
dissolve the ice otherwise may the WEIGHT OF T.L becomes so
heavy and break the structures of the O.H.T.L.
