FIELD: electric engineering, possible use during organization of communication channels using three-phased electric networks (0,4-35)kV without processing thereof with high frequency rejecters.
SUBSTANCE: device contains average voltage line 10 kV, transformers 10/0,4 kV in stations of transfer and receipt, lines 0,4 kV in receipt and transfer stations, voltage filters of symmetric components of direct and reverse order in receipt station, phase shifter, adder, narrowband filter in receipt station, transmitter in transfer station.
EFFECT: production of one-channel receipt of signals on one frequency f0, while increasing signal/noise ratio 2,8 times, in comparison to prototype.
