VLT® AAF Advanced Active Filter
A highly flexible solution for eliminating higher harmonic components. It can be installed centrally for the whole or part of the plant, or separately for each frequency converter separately. Using a suitable transformer, the active filters can also be installed in the medium voltage network. Advanced active filters analyse the harmonic situation of the system and compensate for the higher harmonics present. They can also offset the reactive power in the system.
