Active filters for power systems can be defined as filters that counteract the harmonic currents created by non-linear loads in power systems which could include such devices as computer power supplies, welding equipment, and other active devices which encroach upon the harmonious flow of electricity. Utilizing active filters will allow for the improvement of the intermediate operational efficiency of your power systems, while decreasing the depreciation of electrical devices and equipment. The active filter solutions offered by the Sinotech Group meet International requirements and may be applied in any market.
