Answer / debjyoti guha

corona is a one type of phenomenon, mainly occurs in
transmission line, some electric charge act with surrounding
air moisture. A violet glow mainly seems Also produce
vibration in transmission line And odor....It calculating as
loss of energy.

Answer / karthik_elec

this is one of the reaction in highvoltage transmition line, H.V will ionization the air surrounding by the conductor, it will produce violet glow and vibrations, for reducing this vibration Damper Weight is using in transmition line.

Answer / sonali

corona discharge is a phenomenon which occurs due to the electric breakdown of air particles when the surrounding air between the gap of conductors gets charged in case of high voltages transmissions ,it can also be observed in transformers and is visible with a bluish flame and it actually results in energy loss in the form of heat and light.
