FIELD: communication facilities.
SUBSTANCE: invention relates to method and device for information transmission through network of electrical supply. Method contains stages: electrical element is connected to network through breaker, herewith electrical element normally radiates radio-frequency spurious pulse, when it is connected to network by means of shorting of interrupter and/or when it is disconnect from the network by means of breaking of interrupter, to which it is supplied control signal of defined form so, that electrical element radiates predetermined succession of radio-frequency spurious pulse according to control signal frequency, demodulated radio-frequency spurious pulses and it is reproduced control signal.
EFFECT: reduction of interferences and disturbances.
