FIELD: systems of data transmission over electric power lines.
SUBSTANCE: the device has a transmitter, receiver, modem and a connecter located in two and more points along the electric power line, the connector has capacitance circuits series-connected to a transformer with an air or dielectric core, the capacitance circuits are tuned to resonance with the transformer at a preset frequency, and the connector eliminates interference and is matched with the characteristic impedance of the line at the preset frequency.
EFFECT: enhanced rate of data transmission at large distances over electric power lines.
