The modernization of industrial power systems has been stifled by industry's acceptance of extremely outdated practices. Industry is hesitant to depart from power system design practices influenced by the economic concerns and technology of the post World War II period. In order to break free of outdated techniques and ensure product quality and continuity of operations, engineers must apply novel techniques to plan, design, and implement electrical power systems. Based on the author's 40 years of experience in Industry, Industrial Power Systems illustrates the importance of reliable power systems and provides engineers the tools to plan, design, and implement one. Using materials from IEEE courses developed for practicing engineers, the book covers relevant engineering features and modern design procedures, including power system studies, grounding, instrument transformers, and medium-voltage motors. The author provides a number of practical tables, including IEEE and European standards, and design principles for industrial applications. Long overdue, Industrial Power Systems provides power engineers with a blueprint for designing electrical systems that will provide continuously available electric power at the quality and quantity needed to maintain operations and standards of production.
This title evaluates the performance, safety, efficiency, reliability and economics of a power delivery system. It emphasizes the use and interpretation of computational data to assess system operating limits, load level increases, equipment failure and mitigating procedures through computer-aided analysis to maximize cost-effectiveness.
The performance of grounding grids is critical in safeguarding electrical systems from damage during fault conditions and lightning strikes. Their effectiveness may be compromised under extreme conditions, leading to system failures or safety incidents. Despite advancements in grounding technologies, there remains a need to evaluate and enhance the performance of grounding grids to withstand these scenarios. Engineers, researchers, and industry stakeholders must collaborate to advance testing methodologies, improve design standards, and develop innovative solutions. Effective research and practical improvements in grounding grid systems will ensure reliable protection is provided to safeguard infrastructure and improve safety. Performance of Grounding Grids at Faulty and Lightning Strokes Conditions presents the characteristics of grounding electrodes when subjected to lightning, including the impacts of soil ionization with frequency, soil resistivity, and permittivity variations. The study presents the effects of different reflection factors on human safety through various methods and simulations. This book covers topics such as fault currents, soil ionization, and grounding systems, and is a useful resource for scientists, engineers, technologists, academicians, researchers, and business owners.
The problems of system grounding, that is, connection to ground of neutral, of the corner of the delta, or of the midtap of one phase, are covered. The advantages and disadvantages of grounded versus ungrounded systems are discussed. Information is given on how to ground the system, where the system should be grounded, and how to select equipment for the grounding of the neutral circuits. Connecting the frames and enclosures of electric apparatus, such as motors, switchgear, transformers, buses, cables conduits, building frames, and portable equipment, to a ground system is addressed. The fundamentals of making the interconnection or ground-conductor system between electric equipment and the ground rods, water pipes, etc. are outlined. The problems of static electricity(how it is generated, what processes may produce it, how it is measured, and what should be done to prevent its generation or to drain the static charges to earth to prevent sparking(are treated. Methods of protecting structures against the effects of lightning are also covered. Obtaining a low-resistance connection to the earth, use of ground rods, connections to water pipes, etc, are discussed. A separate chapter on sensitive electronic equipment is included.
This book focuses on protective relaying, which is an indispensable part of electrical power systems. The recent advancements in protective relaying are being dictated by MMPRs (microprocessor-based multifunction relays). The text covers smart grids, integration of wind and solar generation, microgrids, and MMPRs as the driving aspects of innovations in protective relaying. Topics such as cybersecurity and instrument transformers are also explored. Many case studies and practical examples are included to emphasize real-world applications.
Part of the second edition of The Electric Power Engineering Handbook, Power Systems offers focused and detailed coverage of all aspects concerning power system analysis and simulation, transients, planning, reliability, and power electronics. Contributed by worldwide leaders under the guidance of one of the world's most respected and accomplished
This book focuses on instilling a safety culture and fostering the ability to recognize and manage health and safety responsibilities and requirements. It details effective and safety management systems and concentrates on safety and health hazard anticipation, identification, evaluation, and control.
Electric currents and electromagnetic fields have been applied to biological systems, particularly humans, with both therapeutic and pathological results. This text discusses biological responses to electric currents and electromagnetic fields, including medical applications and shock hazards. It covers fundamental physical and engineering principles of responses to short-term electrical exposure and emphasises human reactions, although animal responses are considered as well, and the treatment covers reactions from the just-detectable to the clearly detrimental. An important new chapter discusses standards for human exposure to electromagnetic fields and electric current and demonstrates how these standards have been developed using the principles treated in earlier chapters.
