By Donald G. Baker

Explains and resolves the electromagnetic compatibility demanding situations confronted through engineers in transportation and communications

This booklet is a mathematically-rich extension of classes required to keep up the Federal Communications fee (FCC), the Canadian criteria organization (CSA), and the eu Union certifications. The textual content offers an in-depth research of the electromagnetic compatibility (EMC) matters relating to particular themes in transportation and communications, together with mild Rail Transit, shadow results, and radio useless spots, during the research of real-world case experiences within the usa and Europe. the writer presents Cartesian, cylindrical, and round suggestions that may be utilized to Maxwell's and Wave Equations. The ebook covers themes akin to SCADA structures, protecting, and complexities of radio frequencies and their impact on verbal exchange homes. the writer additionally presents details for substitute industries to use the strategies from the case reports and historical past content material to their very own professions.

  • Presents a sequence of over twenty real-world case experiences relating to EMC in transportation and communications
  • Covers energy line radiation, shadow results on subway autos, teach regulate structures, and aspect distortions
  • Includes the OATS trying out procedure and division of Transportation (DOT) test
  • Provides entry to a significant other site housing strength element slides and extra appendices

Electromagnetic Compatibility: research and Case reports in Transportation is a reference for training engineers fascinated with transportation and communications, in addition to post-graduate engineering scholars learning transportation and communications in engineering.

Example text

The harsh environment from arcing of catenaries and the third hot rail can also be very destructive to other circuits. The tests are conducted on a ground plane with LISN bonded to it. 6. The AC mains should have line filters or isolations transformers and not inject noise into the ­measurements. LISN can be constructed or purchased; however, if constructed poorly they can be a hindrance to measurement accuracy. 7. 5b is the block diagram for a three phase conducted emission test. A LISN is installed on the neutral due to several types of switching DC power supplies that may be connected to the 120 V AC mains and filtering or isolation transformers does not take out all the noise.

Most of the antennas have a matching network built in; these usually have a 2–3 dB loss and generally the manufacturer will provide an insertion loss value. When measurements must be taken for vertical and horizontal polarization there is approximately 20 dB difference between them. For turntable use, the cable between the spectrum analyzer or attenuation and the antenna needs to be extra long to allow for coiling of the cable as the EUT is rotated. The coil cannot be tight or this will introduce a large loss in the cable.

As can be expected the rail right of way authority may lease space for other utilities. 6. This is a description of how a single phase AC voltage measurement is made. The 120 V AC power mains will have an isolation transformer upstream from the LISNs and a copper plate fitted with feed‐through capacitors in the 90° upright; this can be part of the copper ground plane bent to a 90° angle. The ground plane can be solid copper or copper mesh. The LISNs are both bonded to the ground plane. The hot side black wire and white neutral can be measured separately.
