← TechnologyWhich outcome occurs when a synchronous condenser’s excitation circuit fails amidst a prolonged undervoltage condition?
A)Leading VAR output diminishes rapidly
B)Harmonic distortion is marginally increased
C)Reactive power absorption increases steadily✓
D)Voltage regulation immediately stabilizes
💡 Explanation
Reactive power absorption increases because the **field weakening** reduces the counter-electromotive force; therefore, the machine acts more like an inductive load, rather than providing capacitive VARs, especially during prolonged dips in voltage conditions.
