FIELD: electrical engineering.
SUBSTANCE: use in electrical engineering for transmitting information over AC power supply lines with modulation of main harmonic of supply voltage. Method consists in that information intended for transmission is formed into packets, each of which consists of address field and data field, limited by markers, wherein the first and second markers limit the address field – the number of the device for which subsequent data are intended, and the second and third markers restrict the data field. Marker is a half-wave of one half-period of the mains voltage, which is lowered by amplitude.
EFFECT: improved quality of electric energy and electromagnetic compatibility when organizing exchange of information packets along lines of AC power supply.
