    A YnD (star/delta) three phase-to-single phase balance transform features zero negative-phase sequence current, 1.0 of power factor, is able to absorb part of harmonic and in-phase power supply. Its one of secondary windings has a central tap for connecting the phase-shifting capacitor-reactor group with filter function. A phase-shifting reactor is connected between two ends of the winding with tap. The capacity of said capacitor and reactor can be regulated according to load and power factor.
