When the protective capacitor and resistor are connected in series, they form a resistance-capacitance overvoltage absorption device, which can limit the overvoltage when the switch is switched on and off, and protect the electrical equipment. This product can also be used as high-voltage capacitor in other occasions. When it is connected to the ground, it is used to reduce the wavefront steepness and peak value of atmospheric overvoltage, and cooperate with lightning arrester to protect generator, motor and other equipment.
