Harmonic filter is a combination of capacitors and filter reactors in series. That is, capacitive reactive power is generated when the fundamental frequency is 50Hz to meet the requirements of improving power factor, and the inductance of the filter reactor is selected at the harmonic frequency of the filter to cause series resonance, so that the capacitor bank is in resonance. When the wave frequency is 250Hz, 350Hz, 550Hz, a very low impedance is formed, which can absorb most of the harmonic current and improve the voltage distortion rate of the system.
