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. Proposed device includes n-link unit of amplitude and phase optimizers, second n-link unit of mixers and n-link harmonic generator N-link harmonic generator, second n-link mixer unit and n-link amplitude and phase optimizers unit are connected in series. Part of control outputs of n-kink amplitude and phase optimizers unit is connected to controlled inputs of phase shift controllers, and other part of control outputs of n-link amplitude and phase optimizers unit is connected to controlled inputs of n-link unit of scaling amplifiers. Outputs of n-link harmonic generator are connected to part of inputs of second n-link mixer unit to second part of inputs of said unit outputs of n-link interference selector are connected. Outputs of second n-link mixer unit are connected to inputs of n-link amplitude and phase optimizers unit. N-link unit of phase shift elements and n-link unit of scaling amplifiers are connected in parallel, their inputs being connected to outputs of n-link traction current selector, and outputs being connected to inputs of first mixer.
EFFECT: improved stability and quick response in service.
