Where is the best place to remove harmonic currents?
The best place to remove harmonic currents is often at the nonlinear loads that generate harmonic currents or, alternately, at the sub-panels that supply the branch circuits. The object is to reduce harmonic current at a point that is as-close-as-possible to the harmonic generating nonlinear loads. The reduction of harmonic current will result in the reduction of penalty losses. I0Filter or Mini-Z zero-sequence harmonic filters may be used for this purpose.
