Which event triggers cascaded tripping in a three-phase electrical power distribution system due to breaker failure?

💡 Explanation

When a breaker fails to operate correctly, it can cause a surge in current or voltage on the remaining phases, because fault current is not cleared, stressing downstream breakers and triggering their protective functions sequentially. Therefore over-voltage cascading results, rather than overloading, upstream feed, or inductors, which depend on separate protection and control schemes.
