A corona discharge is the ionization of the surrounding atmosphere after an electrical discharge. This can usually be seen as a glowing of a different color near high voltage conductor points.
i dont no about it

Yes.
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.
Corona discharge depends on the frequency of the supply because the alternating electric field influences the ionization of air around conductors. Higher frequencies can lead to more frequent changes in the electric field, promoting ionization and increasing the likelihood of corona discharge. Additionally, at lower frequencies, the time for the electric field to reverse may allow for recombination of ions, reducing corona effects. Thus, the frequency impacts the efficiency and intensity of the corona phenomenon.
Dishonourable discharge
-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
It is based on the principle of static induction and action of points (corona discharge)
When Corona Discharge occurs it forms ozone and nitrogen oxides. These combined with moisture to prduce nitric acid, which is destructive to most dielectrics and certain metallic compositions, resulting in corrosion. In addition, the high energy in some discharges results in mechanical, electrical, and thermal damage. SC
