Which risk increases significantly when high-voltage circuit breakers fail to interrupt?

💡 Explanation

A breaker failing allows fault currents to continue, enabling **cascading failure** because these high currents stress the grid's stability, therefore shutting down interconnected segments, rather than localizing issues, which is what properly functioning breakers accomplish.
