[0002] Power capacitor is the key component of power system and electrical equipment, which is composed of two metal conductors sandwiching insulating medium, and its capacitance value depends on geometric shape and insulating medium characteristics. In an alternating current voltage environment, the capacity of the capacitor is usually measured by reactive power, with units of var or kilovar. Capacitors can be divided into parallel and series according to their use: parallel capacitors are designed to compensate for the reactive power of inductive loads in power systems, improving power factor; series capacitors are used in high-voltage systems to compensate for reactance. According to the structure, there are dry-type and oil-immersed capacitors, etc. Power capacitors are crucial in power systems, and their stable and reliable performance is directly related to the safety of the power grid and the efficient use of energy.
