FIELD: information technologies.
SUBSTANCE: invention may be used to prevent leak of information processed by technical facilities as a result of stray electromagnet radiations and pickups (SERP) along lines of transfer of data of local computer networks (LCN), using twisted pair as the transfer medium. Transformer is arranged with volume short-circuited turn, its primary (1) and secondary (2) windings are wound on separate circular conductors located inside metal sleeves (5, 6) and separated by each other by metal partition (3) connected to busbar of signal grounding of technical facility of information processing. Transformer connection between the primary and secondary windings is done through volume short-circuited turn formed by metal partition (3), metal sleeves (5 and 6), turn (8) passing through geometric centres of primary and secondary windings, nut (9), and simultaneously being electrostatic screen.
EFFECT: improved efficiency of suppression of SERP from technical facilities of information processing in lines of transfer of data of local computer networks (LCN).
