A coupler-integrated transformer for processing power line communication is disclosed. The transformer includes a sensor unit to obtain power and transformer state information, low- and high-voltage power line communication modules to send the power and transformer state information via a low-voltage or high-voltage power line, and to send a communication signal from the low-voltage power line to the high-voltage power line or vice versa via signal amplification, low- and high-voltage power line communication couplers connected to the low- and high-voltage power line communication modules to perform insertion and extraction of the communication signal with respect to a power distribution line, and a microcontroller to process the information from the sensor unit and supply the processed information to the power line communication modules. The transformer enables easy set-up of a communication network system with customers adjacent to the transformer using high-voltage power line communication, achieving a remarkable increase in system capacity.
