DEVICE OF INFORMATION TRANSFER Russian patent published in 2010 - IPC H04B3/54 

FIELD: electricity.

SUBSTANCE: device for information transfer comprises unit of information signals transfer and unit of information signals receiver connected via two transformers of voltage to high voltage power supply line used as line of communication between unit of information signals transfer and unit of information signals receiver unit. As voltage transformers, step-down transformers are used, via which power consumer devices are connected. Output of information transfer unit is connected to the first voltage transformer via the first additional transformer, magnetic conductor of which embraces the line, which connects zero wire of secondary winding of the first voltage transformer with grounding. Input of information signals receiver unit is connected to the second voltage transformer via the second additional transformer, magnetic conductor of which embraces the line, which connects zero wire of secondary winding of the second voltage transformer with grounding.

EFFECT: increased reliability and safety of information transfer device operation in application of high voltage power supply line as line of communication.
