A railway is a complex distributed engineering system: the construction of a new railway or the modernisation of a existing one requires a deep understanding of the constitutive components and their interaction, inside the system itself and towards the outside world. The former covers the various subsystems (featuring a complex mix of high power sources, sensitive safety critical systems, intentional transmitters, etc.) and their interaction, including the specific functions and their relevance to safety. The latter represents all the additional possible external victims and sources of electromagnetic interaction. EMC thus starts from a comprehension of the emissions and immunity characteristics and the interactions between sources and victims, with a strong relationship to electromagnetics and to system modeling. On the other hand, the said functions are achieved and preserved and their relevance for safety is adequately handled, if the related requirements are well posed andmanaged throughout the process from the beginning. The link is represented by standards and their correct application, as a support to analysis, testing and demonstration.

Railway and metro systems embed modern technologies and interface with external systems, outside world and humans. This book focuses on electromagnetic field coupling and its experimental assessment. Electromagnetics, transmission lines, antennas, the spectrum analyzer, time-frequency transforms, probability, statistics and uncertainty are the background. Six chapters follow that discuss standards, scientific literature, measurement methods, procedures. Emissions of rolling stock, line and substation using 2006 and 2015 versions of EN 50121 are considered, discussing infrastructure influence, variability and synchronization with train operation, consistency. RF emissions of current collection system and impact to radio communications are evaluated by means of joint time-frequency transforms, APD and BER. Low-frequency magnetic field is a possible threat to susceptible medical and scientific equipment. For human exposure of personnel and passengers the presence of large power equipment, the relatively short distance and the time-varying nature of sources shall be taken into account with suitable evaluation methods against EN 50550 and ICNIRP limits. The aim is supporting EMC and test engineers, R&D and academic staff in their activities, while planning and preparing on-site tests in modern electrified transportation systems, bridging analysis and simulation. Examples and practical considerations are the result of many years of experience of EMC testing in railways.

This book provides a sound grasp of the fundamental concepts, applications, and practice of EMC. Developments in recent years have resulted in further increases in electrical component density, wider penetration of wireless technologies, and a significant increase in complexity of electrical and electronic equipment. New materials, which can be customized to meet EMC needs, have been introduced. Considerable progress has been made in developing numerical tools for complete system EMC simulation. EMC is now a central consideration in all industrial sectors. Maintaining the holistic approach of the previous edition of Principles and Techniques of Electromagnetic Compatibility, the Third Edition updates coverage of EMC to reflects recent important developments. What is new in the Third Edition? A comprehensive treatment of new materials (meta- and nano-) and their impact on EMC Numerical modelling of complex systems and complexity reduction methods Impact of wireless technologies and the Internet of Things (IoT) on EMC Testing in reverberation chambers, and in the time-domain A comprehensive treatment of the scope and development of stochastic models for EMC EMC issues encountered in automotive, railway, aerospace, and marine applications Impact of EMC and Intentional EMI (IEMI) on infrastructure, and risk assessment In addition to updating material, new references, examples, and appendices were added to offer further support to readers interested in exploring further. As in previous editions, the emphasis is on building a sound theoretical framework, and demonstrating how it can be turned to practical use in challenging applications. The expectation is that this approach will serve EMC engineers through the inevitable future technological shifts and developments.

This is the clear guide for non-specialists to electromagnetic compatability (EMC), the effects of electromagnetic radiation and the European EMC Directive which is now in force. This book helps by explaining the basic principles of EMC, how it may be controlled in practice through filtering, shielding, appropriate printed circuit board design, and other means. Electrostatic discharge (ESD) and surge protection are discussed. The growing concern about the effects of electromagnetic waves and fields on health are examined in detail. This introduction provides beginners, technical and non-technical alike with a basic guide to the principles of EMC. This will prove essential reading for the thousands of people close to despair, giving them the underlying insight, in clear words, that is needed to comply with the EMC Directive, and therefore opens the door to continued trading in Europe and the World. Beginner's guide to EMC ideal for non-technical staff Vital for all businesses who export to either Europe or the rest of the world

Human errors, as well as deliberate sabotage, pose a considerable danger to passengers riding on the modern railways and have created disastrous consequences. To protect civilians against both intentional and unintentional threats, rail transportation has become increasingly automated. Railway Safety, Reliability, and Security: Technologies and Systems Engineering provides engineering students and professionals with a collection of state-of-the-art methodological and technological notions to support the development and certification of ‘real-time safety-critical’ railway control systems, as well as the protection of rail transportation infrastructures.

The integration of electronics in large systems and installations steadily increases, consider for example the emergence of the Industrial Internet of Things. Power consumption decreases while the operating speed increases making equipment potentially more vulnerable for interference. The responsibility of the installer is shifting towards that of the system integrator, requiring more in-depth knowledge to achieve and maintain EMC during the technical and economical lifespan of the system or installation and the distinction between both diminishes. EMC for Installers: Electromagnetic Compatibility of Systems and Installations combines an integral risk based approached to EMC design and management with robust technical measures. Written by two experts, who both started nearly three decades ago in EMC, it provides guidance to those new in the field and servers as reference to those with experience. The book starts with the basic concept of EMC and evolves gradually towards more difficult topics. Particular attention is given to grounding concepts and the protection of cabling and wiring. This book puts a strong focus on passive means that are widely available for each installer: cable conduits used for cable routing can be exploited for significant improvement of the EMC-behavior of the system or installation. In addition, it will be explained how to use standard metallic enclosures to enhance the EMC-performance. For most demanding situations shielded rooms and shielding cabinets are explained. This book describes pre-compliance and full-compliance testing tailored to large systems. Templates and checklists are provided for both risk and management and test management. Electromagnetic compatibility explained as simple as possible, without over-simplifying. Practical approach, with hands-on demonstrations based on an example installation. Learn how to exploit cable conduits, used for cable routing anyway, to improve the EMC performance of an installation. Learn how to exploit standard metallic enclosures to improve EMC in systems. Design of power distribution networks to minimize disturbing fields. Toolbox and templates for managing and sustaining EMC over a long lifetime.
