This practical new resource explores the fundamentals of EMC engineering and examines the concepts and underpinnings of electromagnetics. This book highlights the procedures from design to market for both technical and non-technical issues, including market control, accreditation, calibration, EMC tests and measurement, and EMC protection. Basic electrical engineering theories, Maxwell equations, EM scattering, diffraction and propagation in the electromagnetic model are presented. The circuit model, including lumped parameter circuit elements, two-port circuit definitions, grounding, common and differential model currents, and microstripline circuits are explored. This book also covers antennas and antenna calibration, including communication antennas, normalized site attenuation (NSA), loop antennas, and loop antenna calibration (LAC). Noise and frequency analysis on fundamental electromagnetic signals, noise, and transforms is explained. Readers find insight into EMC test and measurement environments and devices. Time-saving MATLAB code is included in this resource to help engineers with their projects in the field.

Electrical Product Safety: A Step-by-Step Guide to LVD Self Assessment provides a step-by-step approach to meeting the LVD and reducing safety approval costs. It is a practical and easy to follow guide aimed at helping manufacturers of electrical products, and in particular small and medium sized businesses to understand the requirements of the LV regulations, understand the basic safety principles, self assess their products and create customised safety reports. The guide is presented in four parts: the first part examines the regulations, their enforcement and the concept of due diligence; the second and most detailed part takes the reader through the process of product self evaluation and report compilation; part three deals with the documentation, i.e. how to compile a technical file and how to prepare a declaration of conformity; finally part four explains how to set up factory and production control systems. Electrical Product Safety has been written by a Trading Standards Office (D. Holland) and an experienced Safety Approvals Engineer (J. Tzimenakis). A complete, practical guide to meeting core EU legal requirements Designed for easy application by small and medium companies, not just large technical teams Expertise of an author who has set up a similar system at Sony, and supplies supporting software

Practical Guide to International Standardization for Electrical Engineering provides a comprehensive guide to the purpose of standards organizations, their relationship to product development and how to use the standardization process for cost-effective new product launch. It covers major standardization organizations in the field of Electrical Engineering offering a general overview of the varying structures of national standardization organizations, their goals and targets. Key questions for standardization are answered giving the reader guidance on how to use national and international standards in the electrical business. When shall the company start to enter standardization? How to evaluate the standardization in relationship to the market success? What are the interactions of innovations and market access? What is the cost of standardization? What are the gains for our experts in standardization? Key features: Provides guidance on how to use national and international standards in the electrical business. Global active standardization bodies featured include IEEE, IEC and CIGRE as well as regional organizations like CENELEC for Europe, SAC for China, DKE for Germany, and ANSI for USA. Case studies demonstrate how standardization affects the business and how it may block or open markets. Explains the multiple connections and influences between the different standardization organizations on international, regional or national levels and regulatory impact to the standardization processes. Two detailed focused case studies, one on Smart Grid and one on Electro-Mobility, show the influence and the work of international standardization. The case studies explain how innovative technical developments are promoted by standards and what are the roles of standardization organizations are. A valuable reference for electrical engineers, designers, developers, test engineers, sales engineers, marketing engineers and users of electrical equipment as well as authorities and business planners to use and work with standards.

This best-selling text has been revised to reflect the requirements of the 17th Edition of the IEEWiring Regulations (BS 7671: 2008). It includes essential information on the new rules applied to special installations or locations, such as bathrooms, swimming pool locations, camping/caravan sites, marinas, exhibition and show locations, solar photovoltaic power supply systems, and floor and ceiling heating systems, amongst others. It presents clear explanations on inspection, testing, certification and reporting, test instruments and test methods, as well as covering: electricity, the law, standards and codes of practice; assessment of general characteristics; protection against electric shock, thermal effects, overcurrent, undervoltage and overvoltage; isolation and switching; the common rules of equipment selection; switchgear, protective devices and other equipment; wiring systems (including the external influences on them and cable installation methods); protective conductors, earthing and protective bonding; supplies for safety services; the smaller installation, and; specialised installations, such as outdoor lighting, installations in churches, multi-occupancy blocks of flats. These topics are addressed with pertinent regulation numbers, and a useful appendix lists the relevant Standards. Background guidance and worked examples are provided where appropriate. Like the earlier editions of this text, this new edition will be a useful aid for designers, installers and verifiers of electrical installations, students of the industry wishing to gain better understanding of the many facets of electrical safety, and ‘duty holders’ as defined by the Electricity at Work Regulations 1989.
