← TechnologyWhich risk increases when rapidly switching capacitor banks in a power distribution circuit happens?
A)Increased eddy current transformer losses
B)Harmonic resonance throughout the network✓
C)Dielectric breakdown within insulators
D)Increased skin effect along conductors
💡 Explanation
Switching capacitor banks causes network instability because the abrupt voltage change excites the existing inductance, causing harmonic resonance. This happens because the power grids contain inductive and capacitive elements; therefore, resonance occurs rather than a simple change in impedance.
