FIELD: instrumentation.
SUBSTANCE: invention relates to railway automatics and telemechanics. The method to measure asymmetry of alternating traction current in rail lines under ALSS coils consists in the fact that in the required point of the rail line they measure voltage drops in various rail lengths in sections of rails of identical length, or voltages are measured at the outlet of contactless measurement current sensors applied onto different rail lengths in this point. Then by division of difference of these voltages by their sum they find the relative value of traction current asymmetry in this point of the rail line. Additionally a normative shunt is applied onto rails in the measurement point, and measurements are carried out beyond the place of shunt application along with train travel.
EFFECT: increased reliability of measurement.
