Why use a harmonic filter reactor in a power factor correction capacitor bank ?

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.

Benifits of using detuned Reactors

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.
