Railroad Electromagnetic Compatibility: Environmental Tests and Coupling Measurements

摘要

Measurements were conducted at the Electromagnetic Compatibility Test Facility (EMCTF) at Pueblo, Colorado and documented for relevant characteristics of the environment, such as earth resistivity, resistance to remote earth (resistance to ground) of installed grounds, and the dc resistance of the cables that will be used for component testing. Measurements were conducted and documented for the voltage coupled to, i.e., induced into, representative cable conductors and between conductor pairs due to the voltage and current in the catenary. The applicability of analytical coupling models for calculating coupling between the catenary and the parallel communication and signal cables at the EMCTF was investigated.
