← TechnologyWhich outcome occurs when rapid over-correction by anti-islanding protection on a distributed generation circuit breaker precipitates a cascading event?
A)Unintentional island formation develops further
B)Harmonic resonance damages nearby capacitors
C)Reverse power flow disrupts meters
D)Voltage sag destabilizes sensitive loads✓
💡 Explanation
Voltage sag occurs because **sympathetic tripping** extends the initial disturbance, leading to voltage collapse at more distant points; therefore, voltage sag is the result, rather than simple islanding, which protection is designed to prevent, or immediate harmonic effects.
