FIELD: electrical engineering. SUBSTANCE: invention can find use to send information from load-dispatching center of 35.0/10.0/038 kV power lines. In this case cosine capacitors intended to raise cos Φ are installed in 0.38 kV network. Current signals can not be input into line by parallel method in this case as they will be shunted by capacitors. With due account of this fact it is suggested that signal currents should be input into power line of medium voltage of 10.0 or 35.0 kV. Signal current will not be shunted and power of transmitter will be markedly reduced which is technical result of invention. EFFECT: markedly reduced power of transmitter. 1 dwg
