Question:
In case of a transmission line, the corona ______
In case of a transmission line, the corona ______
Show Hint
Corona effect helps mitigate voltage surges by partially dissipating energy during high-voltage events.

- Reduces the magnitude of high voltage steep fronted waves due to lightning or switching
- Increases the magnitude of high voltage steep fronted waves due to lightning or switching
- First reduces and then decreases the magnitude of high voltage steep fronted waves due to lightning or switching
- First reduces and then increases the magnitude of high voltage steep fronted waves due to lightning or switching
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Corona discharge acts like a cushion against sudden high voltage transients caused by switching or lightning by partially ionizing the air and thereby reducing the steepness and magnitude of the wavefront.
