If the operation of loads causing serious harmonics problems calls for an improvement of the network quality, FRAKO Active Filters should be installed.
The harmful effects of harmonics from single loads, load groups or a complete electrical system can be mitigated down to an acceptable degree, if not removed totally from the network.
OSF EZ-Series and OSFS Active Filters combine numerous advantages. They are top-of-the-range instruments hallmarked by extremely short reaction times and selective control up to the 49th harmonic, without current error or phase displacement. The degree of compensation and the control dynamics can be optimized to suit local conditions.
In addition to harmonics compensation, these filters are also suitable for extremely fast control of fundamental-frequency reactive power and for balancing asymmetrical loads. This also reduces the amount of flicker in the network.
