Answer / k.virat kumar

at a one particular volt in tr. line, hessing noise occurs,
that corresponding volt is called discruptive critical
voltage. volt more than this noise a light glow and ozone
layer is produced called corona loss

Answer / naveen

corna loss generally the ionization of the surrounding air

Answer / srinath

when voltage in tr.line increase about particular level than the air insulation across conductor breaks and the power loss occurs in form of hissing noise and violet glow
