Maintaining appropriate power systems and equipment expertise is necessary for a utility to support the reliability, availability, and quality of service goals demanded by energy consumers now and into the future. However, transformer talent is at a premium today, and all aspects of the power industry are suffering a diminishing of the supply of knowledgeable and experienced engineers. Now in print for over 80 years since initial publication in 1925 by Johnson & Phillips Ltd, the J & P Transformer Book continues to withstand the test of time as a key body of reference material for students, teachers, and all whose careers are involved in the engineering processes associated with power delivery, and particularly with transformer design, manufacture, testing, procurement, application, operation, maintenance, condition assessment and life extension. Current experience and knowledge have been brought into this thirteenth edition with discussions on moisture equilibrium in the insulation system, vegetable based natural ester insulating fluids, industry concerns with corrosive sulphur in oil, geomagnetic induced current (GIC) impacts, transportation issues, new emphasis on measurement of load related noise, and enhanced treatment of dielectric testing (including Frequency Response Analysis), Dissolved Gas analysis (DGA) techniques and tools, vacuum LTCs, shunt and series reactors, and HVDC converter transformers. These changes in the thirteenth edition together with updates of IEC reference Standards documentation and inclusion for the first time of IEEE reference Standards, provide recognition that the transformer industry and market is truly global in scale. -- From the foreword by Donald J. Fallon Martin Heathcote is a consultant specializing in power transformers, primarily working for utilities. In this context he has established working relationships with transformer manufacturers on several continents. His background with Ferranti and the UK’s Central Electricity Generating Board (CEGB) included transformer design and the management and maintenance of transformer-based systems. * The definitive reference for all involved in designing, installing, monitoring and maintaining high-voltage systems using power transformers (electricity generation and distribution sector; large-scale industrial applications) * The classic reference work on power transformers and their applications: first published in 1925, now brought fully up to date in this thirteenth edition * A truly practical engineering approach to design, monitoring and maintenance of power transformers – in electricity generation, substations, and industrial applications.

Transformers began with toys and a cartoon series in 1984 and has since grown to include comic books, movies, and video games — its science fiction story has reached an audience with a wide range second only to that of Star Wars. Here, in Transformers and Philosophy, a dream team of philosophers pursues the fascinating questions posed by humankind’s encounter with an artificially intelligent mechanical civilization: Is genuine artificial intelligence possible? Would a robotic civilization come with its own morality and artistic life, and would it find a need for romantic love? Should we be more careful about developing robots that may eventually develop ideas of their own? Transformers and Philosophy puts Transformers under a microscope and exposes its philosophical implications in an instantly readable way.

Recent catastrophic blackouts have exposed major vulnerabilities in the existing generation, transmission, and distribution systems of transformers widely used for energy transfer, measurement, protection, and signal coupling. As a result, the reliability of the entire power system is now uncertain, and many blame severe underinvestment, aging technology, and a conservative approach to innovation. Composed of contributions from noted industry experts around the world, Transformers: Analysis, Design, and Measurement offers invaluable information to help designers and users overcome these and other challenges associated with the design, construction, application, and analysis of transformers. This book is divided into three sections to address contemporary economic, design, diagnostic, and maintenance aspects associated with power, instrument, and high-frequency transformers. Topics covered include: Design considerations Capability to withstand short circuits Insulation problems Stray losses, screening, and local excessive heating hazard Shell type and superconducting transformers Links between design and maintenance Component-related diagnostics and reliability Economics of life-cycle cost, design review, and risk-management methods Parameter measurement and prediction This book is an essential tool for understanding and implementing solutions that will ensure improvements in the development, maintenance, and life-cycle management of optimized transformers. This will lead to enhanced safety and reliability and lower costs for the electrical supply.

'One of my favourite science writers' Bill Gates 'Hugely important' Jim Al-Khalili For decades, biology has been dominated by information - the power of genes. Yet there is no difference in information content between a living cell and one that died a moment ago. A better question goes back to the formative years of biology: what processes animate cells and set them apart from lifeless matter? In Transformer, Nick Lane turns the standard view upside down, capturing an extraordinary scientific renaissance that is hiding in plain sight. At its core is an amazing cycle of reactions that uses energy to transform inorganic molecules into the building blocks of life - and the reverse. To understand this cycle is to fathom the deep coherence of the living world. It connects the origin of life with the devastation of cancer, the first photosynthetic bacteria with our own mitochondria, sulphurous sludges with the emergence of consciousness, and the trivial differences between ourselves with the large-scale history of our planet.
