FIELD: electronics; data transfer systems.
SUBSTANCE: proposed device designed for data transfer over phase conductors of 6-kV power transmission line has high-frequency wavetraps connected at ends of power transmission line in series with phase conductor; data transfer channel is formed by circuit set up of series-connected multiplexing equipment, connection filter, and coupling capacitor at first end of power transmission line and by circuit set up of series-connected coupling capacitors, connection filter, and multiplexing equipment at other end of power transmission line; each of high-frequency wavetraps has two inductance coils, two capacitors, high-frequency matching transformer, and matching capacitor; each connection filter has two inductance coils and three capacitors.
EFFECT: enhanced reliability of multiplexing equipment due to enhanced operating efficiency of high-frequency wavetrap.
