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.

Practical Transformer Handbook shows how a transformer can be put to use, common problems which a user will face, and which is the most appropriate in a particular situation. Anyone working with transformers will find this a valuable user guide. Theory and mathematics are kept to a minimum, and instead the everyday working of these devices is described. Practical Transformer Handbook covers transformers in electronic technology, control techniques, instrumentation, and other more unusual applications. In this practical book a wide range of devices, uses and problems are explored, from parametric transformers, transmission line RF transformers and Tesla coils to the effect of geomagnetic storms on power transformers and dealing with the ever-present third harmonic in iron core transformers. Irving Gottlieb is a leading author of many books for practising engineers, technicians and students of electronic and electrical engineering. - Practical, concise and wide-ranging coverage - Maths and theory kept to a minimum - Written for a wide professional market

Oscillators have traditionally been described in books for specialist needs and as such have suffered from being inaccessible to the practitioner. This book takes a practical approach and provides much-needed insights into the design of oscillators, the servicing of systems heavily dependent upon them and the tailoring of practical oscillators to specific demands. To this end maths and formulae are kept to a minimum and only used where appropriate to an understanding of the theory. Once grasped, the theory of the general oscillator is easily put into practical use in actual oscillators. The final two chapters present a collection of oscillators from which the practising engineer or the hobbyist can obtain useful guidance for many kinds of projects. Irving Gottlieb is a leading author of many books for practising engineers, technicians and students of electronic and electrical engineering. First Newnes title by this best-selling author Clarity and crispness in an often obscure field

This second edition updates what has become a standard reference on the subject, and now includes a selection of highly useful computer solutions to many transformer circuit problems. Every chapter reflects the latest technology advances--and the section on inverter transformers is expanded to better address the increasingly important subject of power supplies.

Covering the fundamental theory of electric power transformers, this book provides the background required to understand the basic operation of electromagnetic induction as applied to transformers. The book is divided into three fundamental groupings: one stand-alone chapter is devoted to Theory and Principles, nine chapters individually treat majo

The book begins with a two-chapter review of fundamental electricity and magnetism and the algebra needed for understanding transformer theory. The properties of transformers are then introduced and the two basic transformer design equations are discussed thoroughly. The important subject of power losses is discussed next, while a chapter is devoted to both the core and windows. Moving from general design considerations to transformer types, the book covers inductors and power, current and impedance transforms. Also treated are transformers as used in converter, inverter and rectifier circuits finally, practical matters, such as transformer construction with salvaged parts, transformers selected off the shelf and checks and tests which can be made on the completed transformer are dealt with.andWritten in an easy-to-understand manner, this profusely illustrated book will be useful not only to the experimenter who wants to construct a transformer but to anyone wishing to gain a deeper and more concrete understanding of transformers.andContentsandChapter 1: andSymbols, Abbreviations and other ReferenceChapter 2: andElementary ElectromagneticChapter 3: andProperties of TransformersChapter 4: and LossesChapter 5: and The CoreChapter 6: and The WindowsChapter 7: and Summarized Data and General Design ConsiderationsChapter 8: and Power TransformersChapter 9: and Designing for RectifiersandChapter 10: Transformers in Converters and InvertersChapter 11: InductorsChapter 12: The Impedance TransformerandChapter 13: The Current TransformerandChapter 14: Salvage, Construction and SourcesChapter 15: Transformers Off the ShelfChapter 16: Tests and

Bushings for Power Transformers, A Guide for Power Engineers There are number of good books on power transformers available in the marketplace and they go into much detail on the theories, designs, construction, components and testing of power transformers. However, they only devote one short chapter to bushings. Bushings are the most important component on your power transformer and one that is maybe least understood. This book will provide the Utility Power Engineer as well as the Utility Technician with a Handbook that will fast become the main reference tool when a bushing issue arises. For the Power Engineer who specifies new power transformers, it will become the go to handbook that will help them to avoid costly mistakes when specifying the bushings in their power transformer specification. This book will review the history of bushings for power transformers and will review the industry standards that apply to bushings. The book covers the different technologies used in bushing construction and will examine the techniques used in the selection of bushings for power transformers. It provides the basic information on bushing tests and how they relate to the power transformers. There is a chapter on maintenance and a guide for replacing bushings. The last chapter deals with a topic that occurs all too often, power transformer failures. This book provides a guide for investigating a power transformer failure when the bushing is suspect. The first hours after a failure is the most critical time help understand what caused the failure. This chapter will help the Utility reach the root cause of the event and hopefully prevent future failures. Every Power Engineer and Power Technician needs Bushings for Power Transformers in their bag of tools as they deal with their power transformers.

This book is based on the author's 50+ years experience in the power and distribution transformer industry. The first few chapters of the book provide a step-by-step procedures of transformer design. Engineers without prior knowledge or exposure to design can follow the procedures and calculation methods to acquire reasonable proficiency necessary to designing a transformer. Although the transformer is a mature product, engineers working in the industry need to understand its fundamentals oand design to enable them to offer products to meet the challenging demands of the power system and the customer. This book can function as a useful guide for practicing engineers to undertake new designs, cost optimization, design automation etc., without the need for external help or consultancy. The book extensively covers the design processes with necessary data and calculations from a wide variety of transformers, including dry-type cast resin transformers, amorphous core transformers, earthing transformers, rectifier transformers, auto transformers, transformers for explosive atmospheres, and solid-state transformers. The other subjects covered include, carbon footprint salculation of transformers, condition monitoring of transformers and design optimization techniques. In addition to being useful for the transformer industry, this book can serve as a reference for power utility engineers, consultants, research scholars, and teaching faculty at universities.
