Active Harmonic Filter

The Active Harmonic Filter (AHF) can be incorporated with any type of non-linear plant loads, under constant or variable load conditions.  The AHF will provide low harmonic distortion and unity power factor to the plant utility grid to help meet the ANSI/IEEE Std. 519-2014 harmonic standards.

This high level of performance eliminates the possibility of high amplitude transient harmonics being reflected back to the utility, or to any other equipment, during sudden load changes. In addition to meeting the standards, utility costs will be lowered and the life of the equipment within the plant will be extended.

The AHF incorporates state-of-the-art UPS technology and the most powerful microcontroller and electronics available in the market today. Its design does not require detailed knowledge of the plant load or the type of harmonics involved. The AHF responds to the exact need as it develops.
