A filter for mitigating harmonics in an electrical distribution system. In one embodiment the filter has one winding that is connected to the power distribution system which may be a three phase system and capacitors are connected to other end of the winding in either a delta or y-connection. There is one tapping on the winding for connection to a load which may an adjustable speed drive. In another embodiment the filter has two or more separate reactors. In either embodiment a switch may be in series with the capacitors and capacitors may be connected in parallel with the series combination of switch and capacitors.
