| description | PROBLEM TO BE SOLVED: To provide a single-phase three-wire alternating power line PLC signal gate device which can prevent a PLC signal flowing through a single-phase three-wire alternating power line at a power receiving side from flowing out to a power supplying side in power line communication using an in-house PLC modem. SOLUTION: The single-phase three-wire alternating power line PLC signal gate device 10 has a first inductive coil L1 inserted into a branching point of a power supplying side and a power receiving side in the single-phase three-wire alternating power line, wherein a neutral line coil L11 of the first inductive coil L1, one side phase winding L12, and other side phase winding L13 are respectively inserted in series into an intermediate portion of a neutral line 9 of the single-phase three-wire alternating power line, an intermediate portion of another phase power line 8 of the single-phase three-wire alternating power line, and an intermediate portion of the other phase power line 7 of the single-phase three-wire alternating power line and a winding direction of one phase winding L12 and a winding direction of the other side phase winding L13 are made opposite to the winding direction of the neutral winding line L11.
