Apfc panel normal, de tuned & tuned
in an industrial plant containing power factor correction capacitors, harmonic currents and voltages can be magnified considerably due to the interaction of the capacitors with the service transformer. This is referred to as harmonic resonance or parallel resonance. For a typical plant containing power factor correction capacitors, the resonant frequency (frequency at which amplification occurs) normally falls in the vicinity of the 5th to the 13th harmonic. Because nonlinear loads typically inject currents at the 5th, 7th, 11th and 13th harmonics, a resonant or near-resonant condition will often result if drives and capacitors are installed on the same system, producing the symptoms and problems with blown fuses, damaged capacitors or failures in other portions of the electrical distribution system.
it is a common misconception that the problem of applying capacitors in harmonic environments is limited to problems caused for the capacitor itself that the capacitor’s lower impedance at higher frequencies causes a current overload into the capacitor and, therefore, must be removed. However, the capacitorharmonics problem must be viewed from a power system standpoint.
Capacitors and transformers can create dangerous resonance conditions when capacitor banks are installed at the service entrance. Under these conditions, harmonics produced by nonlinear devices can be amplified many times. Problematic amplification of harmonics becomes more likely as more kvar is added to a system which contains a significant amount of nonlinear load.
Our normal ,de-tuned & tuned panels are well positioned in market all over india in government ,public & private sectors. We manufacture the same with utmost care so that, simultaneously harmonics and power factor go hand in hand.
Now in india only tamilnadu state govt. Issue harmonics penalty , other states also apply the harmonics penalty in short time.
