← TechnologyWhich risk increases when rapidly cycling on-off a large induction motor via circuit breakers?
A)Bearing race brinelling
B)Transformer core saturation✓
C)Synchronous motor hunting
D)Capacitor bank overvoltage
💡 Explanation
Transformer core saturation risk increases because inrush current through the protection circuit breaker rises during each motor start. Saturation occurs because the magnetic flux density exceeds the core's design limits, therefore protective breaker tripping is more likely, rather than the motor immediately failing.
