First of all ,you have to know what's Harmonic? 

Harmonics are distortion waves in the main voltage or current wave .

It reduces the effective value of the voltage or current (RMS) and increase the losses in form of heat.

So we must eliminate any harmonics by filters.

Harmonis are somtimes useful in heating applications

A distorted current has not just a non-sine wave but also, in some cases, a higher tension value and, since a capacitor is very sensible when the tension is over a maximum level indicated by the manufacturer, then we have a problem!

By eliminating some harmonics, the electric tension from the circuit will be down near the normal level, so the capacitors are safe!

 

But not just for the capacitor banks, but for entire installation filters became a very useful device!

Capacitor banks are actually components of the harmonic filters, so, since someone is using them to improve the power factor, it's a good thing to invest in some coils and he has now an Harmonic Filter, which is very good, especially for the neutral wire!

Wish you the best!

The resonance phenomenon is responsible for the greatest harmonic distortions in

distribution networks and the major cause of correction capacitor overloads. When impedence modules

are generating a maximum number of harmonics, high harmonic voltage is generated it causes a

voltage distortion, and for this a high harmonic current is generated and thus to the risk of overload.

So in this case filter is required.
