We previously proposed a three-phase variable inductor for control equipment in an electric power system. The three-phase variable inductor is constructed with three orthogonal cores that have wedge gaps for reduction of harmonics. When the three-phase variable inductor is connected to a power line in parallel, a simple, reliable var compensator will be realized. In order to reduce the 3rd harmonic of the output currents of the three-phase variable inductor, the secondary windings of the orthogonal cores are connected in a delta configuration. On the other hand, when the three-phase variable inductor is connected other hand, when the three-phase variable inductor is connected to the line in series, the variable inductor can control a power flow in a power system. However, the secondary windings cannot be connected in a delta configuration. In this paper, we present one method of reducing the 3rd harmonic by using the third windings of the orthogonal cores.
