A harmonic capacitor bank is specifically designed to mitigate harmonic distortion in electrical systems, which can be caused by non-linear loads such as variable frequency drives, computer equipment, and other electronic devices. These banks incorporate filters that target specific harmonic frequencies, thereby improving the overall power quality.

5) Harmonic resonance Because capacitors work in the opposite manner to inductors, i.e. they encourage current flow rather than oppose it, they are often used as a solution for power factor correction. The current waveform of a charging and discharging capacitor leads that of the supply voltage waveform. Therefore by connecting the correct
The concept of complex harmonic potential in a doubly connected condenser (capacitor) is introduced as an analogue of the real-valued potential of an electrostatic vector field. In this analogy the full differential of a complex potential plays the role of the gradient of the scalar potential in the theory of electrostatic.

The effects of harmonics on capacitors include additional heating, overloading, increased dielectric or voltage stress, and unnecessary losses, all of which can significantly shorten the lifespan of capacitors.
Capacitors are typically installed in the electrical power system – from commercial and industrial to distribution and transmission systems – as power factor correction devices. However, even though it is a basic component of a harmonic filter (aside from the reactor), it is not free from the damaging effects of harmonics.
Capacitor Bank Behaves as a Harmonic Source. There are many capacitor banks installed in indus- trial and overhead distribution systems. Each capaci- tor bank is a source of harmonic currents of order h, which is determined by the system short-circuit impedance (at the capacitor location) and the capac- itor size.
Also, the combination of harmonics and capacitors in a system could lead to a more severe power quality condition called harmonic resonance, which has the potential for extensive damage. Consequently, these negative effects will shorten capacitor life.

For small capacity rectifier circuits such as those for consumer electronics and appliances, capacitor input type rectifier circuits are generally used. Consequently, various harmonics generated within the power system become a serious problem. Various studies of this effect have been presented previously.
