The corona Effect

The Corona effect is considerably affected by which of the following?

(A) Size of the conductor

(B) Shape of the conductor

(C) Surface condition of the conductor

(D) All of the above

Answer: (D) All of the above

Explanation: 

• A corona discharge is an electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor that is electrically charged. 
• Spontaneous corona discharges occur naturally in high-voltage systems unless care is taken to limit the electric field strength. It is affected by the size of the conductor, shape of the conductor and surface condition of the conductor.
