Active Filters

ABB active filters can be applied to small, medium or large applications and are suitable for both industrial and commercial installations. They provide harmonic mitigation, load balancing and step-less reactive power control for inductive and capacitive loads. Selection from the large choice of ratings from several tens of Amps to several thousands of Amps enables the optimal solution for each system to be easily defined. The desired filter rating can be obtained by combining different master and slave units. Under normal conditions, the load of the filter will be distributed evenly over all the filter units operating in parallel.
