FIELD: electrical engineering; organizing communication channels using power transmission lines without equipping them with rejection filters. SUBSTANCE: method using 0.38-, 10-, 35-, or 110-kV lines for organizing transmission of communication signals at speed of 50 or 100 baud involves synchronous detection of signals using integration whose start and end are determined by characteristic points which are, essentially, moments of total supply voltage transition at transmission and reception centers. EFFECT: improved noise immunity and speed of signal transmission. 1 dwg
