Insulators have a BIL rating, that is the measure of the insulators ability to?

Explanation:
Basic Insulation Level shows how well an insulator can survive a brief, high-voltage spike—like a lightning or switching surge—without breaking down. It’s about transient overvoltages, not the voltage it can carry continuously, nor about storing energy or withstanding physical shocks. So an insulator with a higher BIL is designed to endure larger, short-duration surges without flashover.
