ABSTRACT:
The windings of a wye-connected primary are tapped and connected in a zig-zag fashion to secondary windings. The resulting filter provides phase shifting of load currents and directional filtering of zero phase sequence harmonic currents. The taps may be varied to adjust the voltage output of the apparatus.
