| Abstract | Methods for detecting and quantifying the levels of conductive electromagnetic interference produced by solid state rapid transit propulsion equipment and for determining the susceptibility of signaling systems to these emissions are presented. These methods include procedures for taking measurements in the field, in the laboratory and on track circuits. As background, the mechanisms of conductive electromagnetic interference are described, as are audio-frequency track circuits and solid-state propulsion control. Recording and documentation procedures for applying these suggested test procedures are provided. Appendix A contains definitions of terms and systems of unit. Appendix B contains sample outputs of tests using inductive recommended practices. |
