Despite their essential role in harmonic filters (excluding reactors), capacitors cannot avoid the damaging effects of harmonics. In power systems with high harmonic distortion levels, capacitor banks are especially vulnerable to failure.
The harmonic filter with capacitor bank is widely called a high voltage power capacitor bank. So, this equipment mainly includes 3-phase all film power & capacitors with surge protection. These equipment are enclosed or open, low or high power, fixed power, incorporated or for utilize with separate motors.
The harmonic filter working principle is to decrease distortion through deflecting harmonic currents within less-impedance lanes. These filters are capacitive at the basic frequency, so used to generate the reactive power necessary through converters & also for correction of power factor.
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.
In power systems with high levels of harmonic distortion, capacitor banks are particularly prone to failure. The combination of harmonics and capacitors can lead to a severe power quality issue known as harmonic resonance, which can cause extensive damage and further reduce the life of the capacitors.
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.
