The capacitor does not generate harmonics. However, the capacitor can magnify the harmonic current under resonance conditions. A combination of reactive and capacitive reactance forms a series of resonant circuits. The reactance of the inductor is proportional to the frequency, and reactance increases with an increase in the frequency.

The working of the capacitor banks under a harmonic-rich environment may be adversely affected. The resonance between the inductance of the transformer and the capacitance of the capacitor banks may happen at specific harmonic frequencies. The capacitor does not generate harmonics.
The adverse Effects of Harmonics on Capacitors comprise series and parallel resonance, heating, overloading, and increased dielectric loss. The harmonics also cause a severe problem of resonance that can cause extensive damage. In this post, we will discuss the adverse effect of harmonics on capacitors.
Too large voltage, current, and reactive power harmonics induce capacitor failures. In most cases triplen and even harmonics do not exist in a three-phase system. However, there are conditions where triplen harmonics are not of the zero-sequence type and they can occur within three-phase systems.
The effect is to increase the heating and dielectric stress. ANSI/IEEE, IEC, and European [e.g., 11, 12] standards provide limits for voltage, currents, and reactive power of capacitor banks. This can be used to determine the maximum allowable harmonic levels.
