FIELD: electrical engineering.SUBSTANCE: invention can be used in electrical engineering. Device (200) of communication along power transmission line includes assembly (210) connectors mains with three or more first connectors (211) attached to electrical distribution network. Network filter (220) provides filtration circuit between each of its first ports (221) and corresponding one of second ports (222), wherein each first port (221) is connected to one of first connectors (211). Each second port (222) is connected to one of three or more second connectors (282) of grounding receptacle (280) of AC power supply. Unit (250) of communication along power transmission line is connected with each of first ports (221) and sends and/or receives data according to method of transmitting, in which is more than one transmission channel between two devices connected via electric distributing network. Filter (220) improves quality of transmitting PLC, suppressing noise created devices, and reducing spurious radiation PLC.EFFECT: technical result is simplification of communication system.13 cl, 5 dwg |
