This text studies ways to ground and shield electronic equipment and facilities to control interference. The language of power engineers and the National Electrical Code are explained. The author also lays the ground rules for safety and explains how to attack and solve problems in grounding and shielding via a field theoretic approach rather than a circuit approach. Background theory is given and various hardware and equipment, all key areas in grounding and shielding, ESD, screened rooms, and topics in field coupling are provided.

The Guidebook for Linemen and Cablemen, 2nd Edition is the much needed solution for anyone working on or training to work on electrical utility circuits. Packaged as a convenient, single-volume reference guide on the operation of electrical utility systems, this book will give you what other resources won't: practical coverage of the equipment and situations that power line workers are exposed to on a daily basis, with a focus on ensuring concepts are meaningful and applicable. This book also pays special attention to the order in which topics are addressed; simple concepts are explained first, and the book then builds upon these fundamentals to explain more complex theories, thereby setting a strong foundation for clearly understanding key rules and regulations. This text been updated to include the most current industry information available, including applications of recent technology. This book also contains in-depth exploration of the mechanical aspects of the job, such as working with rigging, trucks, stringing wire, and tree felling. The need for safety and training is highlighted throughout the book, resulting in a powerful resource for linemen, cable men, foremen, and others associated with the transmission and distribution departments of electric utility companies.

A detailed and timely overview of recent developments in active quasi-optical arrays

In recent years, active quasi-optics has emerged as one of the most dynamic fields of contemporary research—a highly unconventional approach to microwave and millimeter-wave power generation that integrates solid-state devices into a single quasi-optical component in which all devices operate in unison. This book defines and describes active quasi-optical arrays, reviews the current state of the art, and answers numerous basic and technical questions on the design, analysis, and application of these devices.

The contributors to this volume are leading researchers in the field who present results and views from government, industrial, and university laboratories and offer a balanced discussion on a high technical level. They also offer insight into the applicability and commercial value of this technology for military systems, manufacturing processes, communications, and consumer products. Topics presented include:

• Analysis and design methodologies for quasi-optical active arrays
• Power-added and power-combining efficiencies of quasi-optical amplifier arrays
• Phase-shifterless beam steering in oscillator and amplifier arrays
• Integrating quasi-optical active components into a compact subsystem
• Design and fabrication of quasi-optical oscillators, amplifiers, multipliers, and tuners
• Characterization and measurement of quasi-optical components

Electricity for HVACR was written to help aspiring technicians with no electrical experience or training to understand the operation of HVACR electrical circuits. The text avoids theoretical discussions of circuits in order to focus on its main goal-showing students how to diagnose and solve electrical problems in HVACR systems. Using the spiral-learning concept, each new unit of the text builds on content learned from the previous unit. From how to use diagnostic tools and instruments safely to understanding diagrams and even coverage of the green ECM motor, the text's many examples, tips, and step-by-step instruction help students learn to apply troubleshooting skills to real electrical problems.

The Seventh Edition of ELECTRONICS FOR ELECTRICIANS is a practical and relevant guide for anyone preparing for a career in industrial settings. With its updated graphics and increased coverage of important topics, this text helps you understand components and circuits in terms of how they work, what they do, how to use them, and how to test them. Review questions and problems in every chapter expose you to the electronic devices commonly found in industry -- as well as the circuit applications of those devices -- while lab experiments give you hands-on experience putting what you learn into practice.

In electrical engineering manufacturing, one of the most important processes stems from making sure the material used to distribute the electrical current is safe and operating correctly. The precarious nature of electricity makes developing innovative material for advanced safety a high-ranking priority for researchers. Electrical Insulation Breakdown and Its Theory, Process, and Prevention: Emerging Research and Opportunities provides innovative insights into the latest developments and achievements in high voltage insulation breakdown. Featuring topics such as nanodielectrics, thermal stability, and transmission technology, it is designed for engineers, including those that work with high voltage power systems, researchers, practitioners, professionals, and students interested in the upkeep and practice of electric material safety.

If you want to introduce alternative power supplies around the home and garden or even live totally off-grid in your boat, caravan or yurt and need a practical introduction to solar power and 12 volt supplies, here is an essential guide to the subject. Not only will it save you money, it will show you how to run your lights, laptop, DVDs and music, and even your tools and household products, from a simple 12 volt system. Be in control of more of your home's own energy supply, develop a low impact way of living and be prepared for power cuts and for power down situations in the future! Do It Yourself 12 Volt Solar Power begins with a lesson in how electricity works and the main components of a DIY solar system. The author uses clear diagrams and terms. There is, of course, more technical information as the book progresses, but don't worry, this no-nonsense guide provides a useful, back-to-basics approach for the layperson. This is a reference book that will help you trouble-shoot and get the best value for money from what you can find hidden in the back of the garage.
