5 Questions
Question 1 of 5
What is the primary cause of the corona effect?
The corona effect is initiated by the ionization of air surrounding a conductor, driven by a sufficiently high voltage.
Question 2 of 5
Which of the following factors increases corona loss?
Higher supply voltage intensifies the electric field, increasing the likelihood and severity of the corona effect.
Question 3 of 5
What is one of the disadvantages of corona discharge?
Corona discharge produces ozone, which can corrode conductors over time.
Question 4 of 5
How does conductor surface affect corona loss?
Smooth conductors distribute the electric field more evenly, minimizing the potential for corona formation.
Question 5 of 5
How can corona loss be minimized?
Increasing the conductor diameter reduces the electric field strength at the conductor surface, reducing corona formation.
