Single-phase line break fault is becoming more and more frequent in low voltage three-phase distribution system. Therefore, once the single-phase line break fault occurs, three-phase loads cannot work, which will cause unnecessary economic loss. This paper proposed a transformer that can transfer power from two-phase to three-phase for single-phase line break fault in low voltage three-phase distribution system. The proposed transformer can solve the problem that these three-phase loads cannot work due to single-phase line break fault. At the same time, the principle that the transformer transfers power from two-phase to three-phase is analyzed. Finally, simulation results verify that the proposed transformer can transfer power from two-phase to three-phase.
