Abstract
Disclosed is an apparatus for power line communication. More specifically, in order to solve a problem of the conventional art, in which the magnitude of power line communication signals exceeds a reference value allowed in the law, the apparatus controls a communication signal to be selectively output a communication target phase among phases of a three-phase power line. Accordingly, it is possible to maintain the magnitude of the output communication signal to be low. Further, it is possible to reduce distortion of a power signal, caused by the communication signal, and malfunction of other power facilities due to the distortion. Further it is possible to easily and simply perform initiation of the power line communication.
