← TechnologyWhich circuit disruption occurs when an inductive load energizes in an AC power system?
A)Inrush current induced oscillation✓
B)Cascading harmonic resonance occurs
C)Over-voltage transient deflection
D)Reactive power factor deviation
💡 Explanation
An inrush current induced oscillation results, because the initial impedance is low and a large current spike occurs, exceeding normal operating levels and causing voltage dips; therefore, oscillation manifests, rather than steady-state harmonics at normal operating temperature.
