High voltage AC filter capacitor

In the power grid, electrical energy is supplied to users with sine wave voltage and current. However, if there are non-linear loads such as rectifiers, inverters, electric arc furnaces, etc., a large amount of high-order harmonic currents will be generated, which will cause distortion of the system voltage and current waveforms, resulting in harmonic pollution of the power system and causing damage to power equipment and electrical equipment. harm. Therefore, when the high-order harmonic current injected into the system exceeds the relevant standards, an AC filter capacitor and other components can be used to form a filter compensation device to absorb high-order harmonics and also serve as reactive power compensation.
