The Effects of Harmonics on Capacitors include additional heating – and in severe cases overloading, increased dielectric or voltage stress, and unwanted losses. 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.
In power systems with high harmonic distortion levels, capacitor banks are especially vulnerable to failure. Harmonic resonance in power systems can be classified as parallel resonance or series resonance, both of which are prevalent in harmonic-rich environments.
As a result, the capacitor bank acts like a sink, attracting unfiltered harmonic currents. This effect increases the thermal and dielectric stresses to the capacitor units (i.e. overload). To illustrate, consider a harmonic-rich electrical system with 5 th harmonic voltage of around 20% the fundamental.
In order to utilize the electrical system effectively, industries are installing capacitor bank in their power circuit. The use of power electronic devices has increased in recent years which resulted in an increase of harmonics in the power system. This has urged the need to study, understand the behavior of harmonics in different conditions.
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.
