This brief develops a data collection plan to assess loss related to electrical surges in homes, and explores the potential impact devices that prevent these surges could have in mitigating these losses. Key topics such as surge sources, surge effects and residential surge protection are clearly defined. Recent fire safety codes proposed a requirement that every dwelling unit be fitted with a surge protection device, as every year there is property damage to electrical and electronic equipment resulting from electrical surges. These proposals have not been implemented due to a lack of reliable data, which this brief seeks to change. The authors evaluate surge phenomena and their sources, surge protection methods, surge protection strategies and industry standards in order to present a data plan that can accurately assess loss related to electrical surges in homes.

As we increasingly use electronic devices to direct our daily lives, so grows our dependence on reliable energy sources to power them. Because modern electronic systems demand steady, efficient, reliable DC voltage sources—often at a sub-1V level—commercial AC lines, batteries, and other common resources no longer suffice. New technologies also require intricate techniques to protect against natural and manmade disasters. Still, despite its importance, practical information on this critical subject remains hard to find. Using simple, accessible language to balance coverage of theoretical and practical aspects, DC Power Supplies, Power Management and Surge Protection details the essentials of power electronics circuits applicable to low-power systems, including modern portable devices. A summary of underlying principles and essential design points, it compares academic research and industry publications and reviews DC power supply fundamentals, including linear and low-dropout regulators. Content also addresses common switching regulator topologies, exploring resonant conversion approaches. Coverage includes other important topics such as: Control aspects and control theory Digital control and control ICs used in switching regulators Power management and energy efficiency Overall power conversion stage and basic protection strategies for higher reliability Battery management and comparison of battery chemistries and charge/discharge management Surge and transient protection of circuits designed with modern semiconductors based on submicron dimension transistors This specialized design resource explores applicable fundamental elements of power sources, with numerous cited references and discussion of commercial components and manufacturers. Regardless of their previous experience level, this information will greatly aid designers, researchers, and academics who, study, design, and produce the viable new power sources needed to propel our modern electronic world.

This book will allow you to gain practical skills and know-how in grounding, bonding, lightning & surge protection. Few topics generate as much controversy and argument as that of grounding and the associated topics of surge protection, shielding and lightning protection of electrical and electronic systems. Poor grounding practice can be the cause of continual and intermittent difficult-to-diagnose problems in a facility. This book looks at these issues from a fresh yet practical perspective and enables you to reduce expensive downtime on your plant and equipment to a minimum by correct application of these principles.Learning outcomes:* Apply the various methods of grounding electrical systems* Detail the applicable national Standards* Describe the purposes of grounding and bonding* List the types of systems that cannot be grounded* Describe what systems can be operated ungrounded* Correctly shield sensitive communications cables from noise and interference* Apply practical knowledge of surge and transient protection* Troubleshoot and fix grounding and surge problems* Design, install and test an effective grounding system for electronic equipment* Understand lightning and how to minimize its impact on your facility* Protect sensitive equipment from lightning· An engineer's guide to earthing, shielding, lightning and surge protection designed to deliver reliable equipment and communications systems that comply with international and national codes · Discover how to reduce plant downtime and intermittent faults by implementing best-practice grounding/earthing techniques· Learn the principles of cable shielding in communication networks

Six-time Hugo winner Ben Bova brings us Power Surge, a gripping political thriller on the cutting-edge of science and technology Dr. Jake Ross came to Washington, D.C., to make a difference. As the science advisor to a newly-elected freshman senator, Jake has crafted a comprehensive energy plan that employs innovative new technologies to make America the world's leader in energy production while simultaneously boosting the economy and protecting the environment. The facts—and the science—are on Jake's side, but his plan soon runs afoul of entrenched special interests, well-funded lobbies, cynical bureaucrats, pork-barrel politics, and one very powerful U.S. Senator. To keep his plan alive and secure a sustainable future for America, Jake needs a crash course in the way Washington really works. Everyone keeps telling him that his plan has no hope of succeeding, but Jake is determined to prove them wrong even if it kills him . . . something that certain hostile parties may be all too happy to arrange.
