Abstract :
The authors present a study of the steady-state and transient effects of power factor correction capacitors on the utility and on the customer. The addition of a power factor correction capacitor in the presence of downstream harmonic loads and at the harmonic load site is considered. In both cases the resonance created by the addition of the capacitor caused the harmonic distortion of the voltage and current waveforms to increase. Another problem is transient overvoltages created by switching the capacitor. The steady-state concerns associated with the application of power factor correction capacitors in the presence of harmonic loads and unbalance are addressed. The transient problems associated with the switching of power factor correction capacitors are considered
