FIELD: electric engineering, can be used for organization of communication channels with use of three-phase electric networks (0,4 - 35) kV, without processing by high frequency wave-traps. ^ SUBSTANCE: at N=1,2,3,...,N control stations only transmitters are present, and at dispatching station only receiver is present. ^ EFFECT: considering that costs of receiver is 2,5-3,5 times higher than cost of transmitter, cost of channel-forming equipment is significantly reduced. ^ 1 dwg |
