High voltage capacitors are classified by application. Commonly used types include shunt capacitors, series capacitors, AC filter capacitors, and DC filter capacitors. Shunt capacitors are widely used in AC power systems of 1kV and above, primarily for reactive power compensation, improving the power factor of transmission lines, reducing line losses, improving voltage quality, and enhancing the ability of power transmission and transformation equipment and lines to transmit active power. Series capacitors are connected in series in AC power systems to compensate for the inductive reactance of power lines, thereby improving system voltage, reducing energy losses, increasing line stability, and enhancing power transmission capacity. AC filter capacitors are connected with other devices to form AC filters and are connected in parallel in high-voltage AC power systems to provide low-impedance paths for one or more harmonic currents, reducing network harmonic levels while improving the system's power factor. DC filter capacitors are mainly used in high-voltage rectification and filtering devices and high-voltage direct current transmission (HVDC).
