SYSTEM OF SIGNAL TRANSMISSION AND RECEPTION OVER WIRES OF THREE PHASE TRANSMISSION LINE Russian patent published in 1998 - IPC

Abstract RU 2115238 C1

FIELD: electrical engineering. SUBSTANCE: system may be used to form communication channel at voice frequencies over lines of 0.38-10-35 kV without their high-frequency processing. Dispatching and controlled stations of system have transformers of 6-10/0.4 kV, first and second filters, telecontrol, telesignalling and telemeasuring unit, transmitter, first and second balance phase detectors, local oscillator, phase inverter, current transformer, and shunting element. EFFECT: transmission of information over synchronous communication channel. 1 dwg
