With the modern power electronic equipment and other non-linear load access to a large number of power grids, so that the quality of power supply network has been seriously affected, in which a large number of various applications of power electronic switching devices lead to the generation of harmful high harmonics, resulting in grid voltage distortion Power equipment malfunction, heat, loss, instability, overload, damage, reduce production efficiency and interfere with communication signals. The installation of filter compensation device can effectively improve the power quality, reduce harmonic pollution, improve production efficiency.

        FC main role is to eliminate the harmonic and improve the power factor, by the filter capacitor, filter reactor and filter resistors. The device is safe and reliable, less investment, widely used in metallurgy, coal and other industries in the load fluctuations in the place.
