The standard, unchoked capacitors in the APFC System offered very low impedance to harmonic currents thus acting as sink for higher frequency components. Hence, considering the amplification characteristics of the existing Capacitors and the basic nature of loads like UPS, Air conditioners and Lighting Systems in the network, it was necessary to find a suitable solution to the issue. After a detailed study and analysis of the key parameters, a solution of a Reactive Power Compensation with Harmonic Blocking filters to prevent any failure of capacitors, was recommended. However the solution was not implemented due to the perceived 'high cost' and the problems used to affect the system operation only occasionally by the center.ADDITIONAL INFO Author:T.S.KANTHI Technical Director Country:BARON Power Ltd.

You would use capacitors if the power factor is leading and inductors if the power factor is lagging. Manufacturing plants use three phase power and a home uses single phase so there is no advantage in using capacitors or inductors to improve power factor in a home.LEAVE A COMMENTMake sure you enter the (*) required information where indicated.
