← TechnologyWhich outcome results when a three-phase induction motor circuit breaker trips due to excessive inrush current during start-up?
A)Voltage sag across distribution network✓
B)Increased reactive power compensation
C)Harmonic distortion in supply voltage
D)Phase imbalance along transmission lines
💡 Explanation
When a motor starts, high inrush current flows momentarily pulling the voltage down because the current exceeds system capacity resulting in increased impedance. Therefore a voltage sag results, rather than reactive power increase, harmonic distortion, or phase imbalance, which require different operational conditions.
