Abstract
A disclosed PLC system includes a PLC modem electrically connected to a transmission medium that transmits or carries medium or high voltage without electrical isolation. The PLC system further includes a voltage divider that draws power from the transmission medium to the PLC modem, thereby eliminating a need of a separate power source for operating the PLC modem. Since the PLC modem is electrically connected to the transmission, the PLC modem or communication connections of the PLC modem may be located at a same potential level as the transmission medium and thus the PLC modem does not see a surge during a surge event occurs in the transmission medium. Therefore, the disclosed PLC system eliminates the use of a line coupler and a surge protection component for providing high-voltage isolation and surge protection to the PLC modem.
