Which outcome occurs when a large industrial motor overheats coincident with brief power interruption, leading to breaker trip?

A)Sequential tripping of upstream breakers
B)Harmonic resonance in grid capacitors
C)Over-compensation by automatic voltage regulator
D)Delayed reclosure due to anti-pumping

💡 Explanation

The heated motor draws locked-rotor current, exacerbated by simultaneous restarts after brief power loss; because inverse-time characteristics of breakers mean that the downstream breaker may fail to trip faster than its upstream cousin during sudden high-current inrush situations, therefore potentially leading to cascading failures, rather than local shutdowns.
