-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...
The virtual diameter of the conductor becomes greater to carry more current
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.
Corona discharge offers several advantages, including the ability to generate ozone efficiently, which is useful for air and water purification. It operates at relatively low temperatures, minimizing thermal damage to materials. Additionally, corona discharge can enhance the surface properties of materials, improving adhesion and wettability in various industrial applications. Lastly, it is an effective method for controlling pollutants and has applications in advanced manufacturing processes.
