← TechnologyWhich outcome occurs if a circuit breaker trips repeatedly in a dynamically balanced three-phase motor control system?
A)Motor overheating becomes more probable✓
B)Harmonic distortion within the system
C)Increased drive system efficiency overall
D)Consistent voltage waveforms in components
💡 Explanation
Repeated breaker tripping typically indicates an overcurrent condition due to locked rotor, because stalled current creates high heat, and causes *thermal overload*. This results in motor overheating, therefore motor burnout becomes probable, rather than efficient motor operation through reduced harmonics.
