Delta circuit embedded contactors of a harmonic filter apparatus and method of use thereof

Abstract

The invention comprises a harmonic filter apparatus and method of use thereof, the harmonic filter including a delta circuit comprising: (1) a first leg connecting a first apex to a second apex of the delta circuit; a second leg connecting the second apex to a third apex of the delta circuit; and a third leg connecting the third apex to the first apex and (2) a first electrical contactor and a second electrical contactor positioned within at least two of: the first leg, the second leg; and the third leg. Optionally and preferably, each apex of the delta circuit is connected to individual phases of three phase power via respective inductor—coupled inductor pairs, where the harmonic filter magnetically isolates individual phases of the three phase power.
