Q: What is a capacitor switch?
A: A capacitor switch is an electrical device used to control the input and removal of a capacitor bank. It plays an important role in the power system.
Q: What is the function of capacitor switch?
A: The main function is to adjust reactive power. When the reactive power is insufficient in the power grid, the switch will put the capacitor in to compensate the reactive power, improve the power factor, improve the power quality, and reduce the line loss. When the reactive power is in excess, the capacitor can be removed.
Q: What should I pay attention to when using capacitor switch?
A: It should be noted that the switching frequency cannot be too high to avoid damage caused by frequent action of the capacitor. At the same time, it is necessary to reasonably choose switching according to the actual situation of the power grid
