← TechnologyWhich outcome can overload protection systems trigger in three-phase induction motor circuits during startup?
A)Nuisance tripping due to inrush current✓
B)Resonance oscillations from capacitor switching
C)Harmonic distortion from rectifier feedback
D)Voltage sag from transformer saturation
💡 Explanation
During motor startup, high inrush current occurs because the rotor is initially stationary, presenting low impedance; protective systems misinterpret this transient as an overload, causing nuisance tripping. Therefore, nuisance tripping results, rather than resonance, distortion, or sag, which involve different electrical phenomena.
