← TechnologyWhich outcome occurs when capacitive load energization causes inrush current via distribution circuit breaker?
A)Nuisance tripping due to high di/dt✓
B)Voltage sag from transformer saturation
C)Harmonic distortion from diode clipping
D)Increased power factor from current lead
💡 Explanation
When energizing a large capacitive load, a high inrush current occurs due to low initial impedance, causing a rapid change in current (di/dt) which a circuit breaker interprets as a fault condition, leading to unwanted tripping. Therefore, nuisance tripping results, rather than voltage sag, distortion, or power factor changes which require different power system failure mechanisms.
