← TechnologyWhich outcome occurs when adaptive reclosing logic fails in distribution circuit breakers?
A)Prolonged fault current interruptions
B)Transient voltage surge propagation
C)Sympathetic trip cascading failures✓
D)Increased harmonic resonance amplification
💡 Explanation
The risk of widespread blackout escalates given adaptive reclosing failure, because a `sympathetic trip` occurs; upstream breakers trip unnecessarily due to fault current, therefore collapsing power grid stability, rather than localized fault isolation.
