← TechnologyWhich consequence results when capacitor bank switching causes transient overvoltages in utility scale electrical grids?
A)Harmonic resonance destabilizes the system✓
B)Improved power factor minimizes faults
C)Transformer core saturation reduces losses
D)Voltage regulation increases system efficiency
💡 Explanation
Line energization surge creates oscillation; because transient overvoltages excite harmonic frequencies, harmonic resonance is amplified and therefore destabilizes the electrical grid system, rather than creating the reverse effect by improvement for the system.
