CORONA EFFECT OCCURS IN O.H CONDUCTOR, WHEN APPLIED 30 KV /
CM, STARTS MAGNETIC FIELD AROUND IT WHICH ENERGISE THE
VELENCY ELECTRONS AROUND IT, ENERGISED ELECTRON GOT
VELOCITY STRIKES THE NEUTRAL ATOMS, CHARGES ITS FREE
ELECTRONS & THE PROCESS GOES ON THEN STARTS INERACTION WITH
THE PARALLEL CONDUCTOR'S SAME PROCESS, MORE CORONA EFFECT
OCCURS WHEN APPLIED VOLTAGE INCREASED MORE THAN 30 KV / CM,
THE EFFECT WILL BE EVEN MORE, WHERE THE CONDUCTOR DURTY &
COVERED WITH DUST, ALSO OCCURS AT ROUGH SURFACE OF THE
CONDUCTOR, LOOKS IN VIOLET COLOUR THAT TO IN NIGHT,HISSING
SOUND OF CORONA CAN BE HEAR BY DISTANCE.
