Certification testing of railway rolling stock in the field of EMC –

The paper presents the issues of electromagnetic compatibility assessment of railway rolling stock, the emission levels of disturbances generated by the rolling stock in relation to the permissible levels specified in dedicated standards. The assessment of the generated level of radio-frequency disturbances consists of measuring the field strength value at a distance of 10 m from the axis of the track on which the tested locomotive is moving. The paper presents the results of measurements of radiated emissions by an electric multiple unit (EMU) type 22WE with a power of 4 x 500 kW. The results of conducted emission measurements in the on-board low-voltage network are presented. The paper also describes a method for estimating measurement uncertainty in disturbance emission testing of railway rolling stock.CERTIFICATION TESTING THE SCOPE OF ROLLING STOCK EMC METHODS, PROBLEMS
The paper studies the evaluation of electromagnetic compatibility of railway rolling stock, the emissions generated by rolling disorders in relation to acceptable levels recorded in the dedicated standards. Staff generated the level of disturbance is based on measuring the value of field strength at a distance of 10 m from centre of the track, which moves the test locomotive. The paper presents results of measurements of emissions radiated by an
EZT type 22WE 4 x 500 kW. Presented results of measurements conducted emission in the on-board low voltage network. The paper also describes a method for estimating the uncertainty in the emissions testing problems of rolling stock. (…)
