← TechnologyWhich outcome occurs when significant harmonic currents flow through a power distribution circuit containing a capacitor bank?
A)Resonance causing overvoltage and equipment damage✓
B)Reduced power factor due to harmonic cancellation
C)Improved voltage regulation at the load bus
D)Decreased transformer core losses and heating
💡 Explanation
When harmonic currents are present, the capacitor bank's impedance interacts with the source impedance, causing resonance if the harmonic frequency is near the resonant frequency, leading to overvoltage and equipment damage. Therefore overvoltage occurs, rather than power factor improvement, voltage regulation, or reduced losses because of the specific resonant interaction.
