The VLT® LHD is the first solution to combine an active filter and a drive in one package. It continuously regulates harmonic suppression according to the load and grid conditions without affecting the connected motor. The total harmonic current distortion is reduced to less then 3% on grids with balanced mains, a minimum pre-distortion to less than 5% on grids with high harmonic distortion and 2% phase unbalance. The VLT® Low Harmonic Drive meets all present harmonic standards and recommendations.
