Condition monitoring of engineering plant has increased in importance as engineering processes are automated and manpower is reduced. However, electrical machinery receives attention only at infrequent intervals when plant is shut down and the application of protective relays to machines has also reduced operator surveillance.A first edition of Condition Monitoring of Electrical Machines, written by Tavner and Penman, was published in 1987. The economics of industry have now changed, as a result of the privatisation and deregulation of the energy industry, placing emphasis on the importance of reliable operation of plant, throughout the whole life cycle, regardless of first cost. The availability of advanced electronics and software in powerful instrumentation, computers, and digital signal processors (DSP) has simplified our ability to instrument and analyse machinery. As a result condition monitoring is now being applied to a wider range of systems, from fault-tolerant drives of a few hundred watts in the aerospace industry, to machinery of a few hundred megawatts in major capital plant.In this new book the original authors have been joined by Ran, an expert in power electronics and control, and Sedding, an expert in the monitoring of electrical insulation systems. Together the authors have revised and expanded the earlier book, merging their own experience with that of machine analysts to bring it up to date. The book is aimed at professional engineers in the energy, process engineering and manufacturing industries, plus research workers and students.

Condition monitoring of engineering plants has increased in importance as engineering processes have become increasingly automated. However, electrical machinery usually receives attention only at infrequent intervals when the plant or the electricity generator is shut down. The economics of industry have been changing, placing ever more emphasis on the importance of reliable operation of the plants. Electronics and software in instrumentation, computers, and digital signal processors have improved our ability to analyse machinery online. Condition monitoring is now being applied to a range of systems from fault-tolerant drives of a few hundred watts to machinery of a few hundred MW in major plants.This book covers a large range of machines and their condition monitoring. This 3rd edition builds on the 2nd edition through a major revision, update of chapters and a comprehensive list of references & standards. Permanent magnet, switched reluctance and other types of machines are now covered, as well as variable speed drive machines and off-line techniques.Contents cover an introduction to condition monitoring; rotating electrical machines; electrical machine construction, operation and failure modes; reliability of machines and typical failure rates; signal processing and instrumentation requirements; on-line temperature monitoring; on-line chemical monitoring; on-line vibration monitoring; on-line current, flux and power monitoring; on-line partial discharge (PD) electrical monitoring; on-line variable speed drive machine monitoring; off-line monitoring; condition-based maintenance and asset management; application of artificial intelligence techniques to CM; and safety, training and qualification.

Rotating electrical machines are embedded in nearly every sector of modern industry; they are widely used in industrial settings, as motors in transportation applications - including electric vehicles - and in power generation, where they are a key component of wind turbines.Technical advances are transforming what these machines can achieve. New developments in rotating electrical machinery have arisen from novel or improved materials, including new insulation materials, as well as advances in electrical steels and high-performance permanent magnets, and more rapid mass production techniques. These improvements deliver benefits such as cheaper and faster manufacturing and enhanced performance from the final products. At the same time, condition monitoring and maintenance techniques are also changing rapidly through increased application and further research and development, and are becoming essential to ensuring reliability, availability and cost-effectiveness for electrical machine systems, from small industrial drives to multi-megawatt generators.Condition Monitoring of Rotating Electrical Machines has established itself as a definitive reference for researchers and engineers in the energy, transport, process engineering and manufacturing industries and in related academic research. Coverage includes fundamental principles of condition monitoring, plus in-depth discussion of reliability, signal processing, online temperature, chemical and vibration monitoring, current, flux and power monitoring, partial discharge detection, drive monitoring, off-line monitoring, condition-based maintenance, use of AI and machine learning, and safety and training.This 4th Edition has been expanded, revised and updated throughout, and features new chapters, addressing novel machine designs, new materials, clean energy and transport, the use of AI, and strategies for reliability, availability and maintenance.

Clean energy provision and usage has a long history from an engineering perspective. This perspective can help understanding past and current developments at a time of increasing concern about climate change. Over many hundreds of years human beings have been extracting energy from their environment in various ways, many of which could also be acceptable in the future for achieving a lower energy carbon footprint.This book for engineers, researchers and scientists in the renewable energy industries as well as for advanced students, investors, managers, and engineering historians, describes the engineering history of human methods for extracting energy from our environment, up to and including the electrical age.Chapters cover the ancient and historical past, fuels between 1800 and 1900, science, engineering and electricity in the modern age, current energy vectors, clean and renewable energy, and an outlook to the future.The book places those aspects and developments in context alongside present usage. It presents energy data in graphical or schematic ways to indicate these changes in different world regions, putting them in historical context. The goal is an understanding of the range of energy resources available to us from our environment.

The potential of wave power lies in waves' kinetic energy. Waves have a far greater energy density than wind or solar and can generate between 24-70 kW per meter of wave. The global tidal energy potential is estimated to be 3 TW, with approximately 1 TW in comparably shallow waters. The challenge for the development of marine energy converters (MEC) is to achieve an investment cost and rate of return that will make marine energy devices viable, compared to other sources of electrical power.The first edition of this work provided a description of the reliability and availability issues facing new wave and tidal generation devices. Since publication, there has been growing activity world-wide. The 2nd edition brings this activity to light; chapters cover, after an overview, the principles, reliability in theory and practice, a range of devices and device taxonomy, availability, device layout and grid connection, design and testing for wave and tidal devices, monitoring, as well as operational experiences and lessons learnt from existing systems.Wave and Tidal Generation Devices, 2nd Edition is a key resource for researchers and developers in industry and academia involved with wave or tidal energy devices, for experts responsible for operating and maintaining wave and tidal assets, as well as for advanced students involved with ocean energy technology engineering.

The development of offshore wind power has become a pressing modern energy issue in which the UK is taking a major part, driven by the need to find new electrical power sources, avoiding the use of fossil fuels, in the knowledge of the extensive wind resource available around our islands and the fact that the environmental impact of offshore wind farms is likely to be low.However, there are major problems to solve if offshore wind power is to be realised and these problems revolve around the need to capture energy at a cost per kWh which is competitive with other sources. This depends upon the longevity of the wind turbines which make up offshore wind farms. Their availability, reliability and the efficacy and cost-effectiveness of the maintenance needed to achieve that availability, are essential to improve offshore wind life-cycle costs and the future of this emerging industry.This book intends to address these issues head-on and demonstrate clearly to manufacturers, developers and operators the facts and figures of wind turbine operation and maintenance in the inclement offshore environment, recommending how maintenance should be done to achieve low life-cycle costs.
