FIELD: electrified railways.
SUBSTANCE: device relates to sphere of electrified railways and it can be used to reduce effect of electrified railways onto adjacent communication lines. Differential transducer measuring speed of current change in traction system is arranged between effecting suspension and return wire, being connected by output to input of cutoff unit of adjustable current source at emergency situations connected by its output with input of adjustable current source interlock connected to input of compensation system matching unit with shielded wire placed in series with shielded wire at one of its ends.
EFFECT: improved reliability in operation, increased efficiency of compensation of induced interference in adjacent line.
