Capacitors are required to improve power factor and possible harmonic interaction may occure with the installation of a plain capacitor bank.
Permissible distortion limits of the local utility of IEEE-519 are exceeded and filters are required to reduced them.
A comination of PFC capacitors with detuned harmonic filter reactors will result in limiting harmonics.
Prolongs life of PFC capacitors by reducing harmonic overloading with respect to voltage & current.
Reduces amplification of system harmonics thereby restoring sinusoidal waveform.
Reduce over heating of busbars, cables & transformer.
