The "switching" here refers to the act or process of connecting the capacitor compensation device to the compensated system, or disconnecting the capacitor compensation device from the compensated system.
The switching method, the way to connect the capacitor compensation device to the compensated system. For example, manual switch switching, relay switching, thyristor switching.
Reactive power compensation, known as reactive power compensation, is a power supply system in the electric power to improve the power factor of the grid, reduce the power supply transformer and transmission line losses, improve the efficiency of the power supply, improve the power supply environment of the technology. So the reactive power compensation device in the power supply system in an indispensable and very important position. Reasonable choice of compensation device, can do to minimize the loss of power grid, so that the quality of the power grid to improve. On the contrary, if the choice or use of improper, may cause the power supply system, voltage fluctuations, harmonic increase and many other factors. Detailed description of the basic principle of reactive power compensation, meaning, casting mode, line, controller, high and low voltage devices, compensation methods, problems and so on.
