-it prevents conductor from electrical surges
-it increases virtual diameter hence conductor can carry more current
-corona discharge is used in photo copier and laser printers
frequency is directly propotional to corona loss... so higher the freq the corona also high..

to have large diameter without increasing its weight.
Due to corona effect virtually conductor size is increase and therefor resistance in transmission line is decreases.so I2R losses will decreases...
A: Transmission lines while there is ceramic insulators providing separation to the phases will have a corona if the insulators are dirty providing small current leakage ionizing the air around it therefore corona effect.
The virtual diameter of the conductor becomes greater to carry more current
The corona.
Today, only loss !
