FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used to transfer n-phase voltage via a fibre-optic line. For this purpose, device for transmitting a multi-phase voltage system via a fibre-optic line additionally includes sinusoidal EMF generator 8, phase shifting circuits 9i (i = 2..n), second transistor switches 10i (i = 1…n), group of inverters 12i (i = 1…n), adders 13i (i = 1…n), analogue-to-digital converters of discrete phase voltages (ADC) 14i (i = 1…n), group of OR elements 15, first fibre-optic link (FOL) 16, second fibre-optic link 17, second decoder 18, groups of second AND elements 19i (i = 1…n, n is the number of phases in the network), digital-to-analogue converters (DAC) 20i (i = 1…n), power amplifiers.
EFFECT: technical result is improving reliability of the device by transmitting multi-phase voltages over long distances.
