FIELD: transportation, electricity.
SUBSTANCE: method lies in generating current in return conductor, giving rise to secondary compensating electromagnetic field, which is in phase opposition with the electromagnetic field of the traction current of the contact network. The parameters of the "return conductor - earth" contour, for each of the compensating harmonics, is varied until reaching a mode, close to the mode of resonance of voltages, or directly to the mode of resonance of voltages.
EFFECT: more efficient compensation of electromagnetic interference in adjacent communication lines.
