Methodology for measuring radioelectric disturbances in the on-board low-voltage power supply network

The paper presents the issues of testing railway rolling stock in terms of conducted disturbance emissions in the on-board low-voltage power supply network in relation to the permissible levels contained in standards, using the 16 Wek (ED74) electric multiple unit as an example. Furthermore, the main sources of radioelectric disturbances occurring in the on-board power supply network are presented. The measurement methodology is discussed, and exemplary results of both normative and additional measurements are provided, recorded in configurations with filters switched on and off at the substation at various speeds.

METHODS OF MEASUREMENT OF RADIOELECTRIC DISTURBANCES IN ON BOARD LOW VOLTAGE SUPPLY NETWORK

The paper presents the research problem of railway rolling stock in scope of disturbances emission conducted in low voltage on board supply network. This research refers to permissible levels included in the norms and based on example of electric multiple units 16 Wek (ED74). Moreover the paper presents major sources of radio electric disturbances in on board supply network. The paper discusses the methodology of measurements and contains an exemplary results of normative and additional measurements in configuration with switch off and switch on filters in substation

,registered with different speed. (…)
