DEVICE TO REDUCE ELECTROMAGNETIC INTERFERENCES ON COMMUNICATION LINE Russian patent published in 2010 - IPC B60M1/06 

FIELD: transport.

SUBSTANCE: device relates to electrified railways and serves to reduce contact circuit influence on adjacent communication lines. Compensation effect is base on ruling out dynamic effects on compensation process and harmonics current induced in shielding wire carrying main power of traction current signal and making main part of their spectrum. Compensation device additionally comprises capacitor connected in shielding wire break. Note here that said capacitor features resistance highest for 1^st, 3^rd and 5^th harmonics of compensation current spectrum induced in reverse wire ruling out or reducing their presence in the latter. Hence, dynamics effects of aforesaid harmonics ob compensation process and device are ruled out.

EFFECT: higher reliability.
