Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the physics of electrical insulation, this book presents the physical foundations of this discipline and the resulting applications. It is structured in two parts. The first part presents a mathematical and intuitive approach to dielectrics; various concepts, including polarization, induction, forces and losses are discussed. The second part provides readers with the keys to understanding the physics of solid, liquid and gas insulation. It comprises a phenomenological description of discharges in gas and its resulting applications. Finally, the main electrical properties of liquids and solids are presented, in order to explain the phenomena of electrical degradation, dissipation and breakdown. Contents 1.

This book was released on 2010-08-05 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: An accurate quantitative picture of electric field distribution is essential in many electrical and electronic applications. In composite dielectric configurations composed of multiple dielectrics, anomalous or unexpected behavior of electric fields may appear when a solid dielectric is in contact with a conductor or another solid dielectric. The electric field near the contact point may become higher than the original field not only in the surrounding medium but also in the solid dielectric. Theoretically it may become infinitely high, depending on the contact angle. Although these characteristics are very important in a variety of applications, they have been clarified only recently using analytical and numerical calculation methods, and this is the first book to cover these new findings. Electric Fields in Composite Dielectrics and Their Applications describes the fundamental characteristics and practical applications of electric fields in composite dielectrics. The focus is on the field distribution (and the resultant force when appropriate) near points of contact. Applications include insulation design of high-voltage equipment with solid insulating supports, utilization of electrostatic force on dielectric particles in electrophotography and electrorheological fluids, and others. Electric Fields in Composite Dielectrics and Their Applications also explains the calculation methods used to analyze electric fields in composite dielectrics.

Available in PDF, EPUB and Kindle. Book excerpt: Research in solid-state physics in general and in the physics of dielectrics in particular has grown rapidly in scope and quan tity in the last twenty-five years. In the fifties and early sixties, there was an upsurge of interest in ferroelectricity, piezoelectrici ty' and pyroelectricity. The classical physics of dielectrics, rep resented by books of H. Frohlich, C.P. Smyth, G.I. Skanavi, and A. von Hippel, is now unthinkable without ferroelectricity. The structure and properties of ferroelectrics have been described in a number of books and reviews, including those of W. Kanzig, H.D. Megaw, F. Jona and G. Shirane, W.J. Merz and E. Fatuzzo. The present work deals with the physics of crystalline di electrics and is based on the investigations carried out by scien tists throughout the world. But, understandably, the emphasis is on the research done in the USSR, particularly in the author's labo ratory. A special feature of this two-volume treatise is the pro minent place given to the symmetry and structure of dielectrics and to the importance of spontaneous electric polarization in many properties of crystals. In fact, these aspects take up the whole of the first volume. The second volume is concerned mainly with various properties and phenomena whose nature is illustrated by considering specific crystals. Thus, for example, the phenomena of polarization, piezoelectricity, electrostriction, etc., are first discussed in detail. Then follow descriptions of these phenomena in specific compounds.

Available in PDF, EPUB and Kindle. Book excerpt: Liquid dielectrics provide superior electrical breakdown strength and heat transfer capability, especially when used in combination with liquid-immersed solid dielectrics. Over the past half-century, there has been extensive research characterizing "streamers" in order to prevent them, as they are the main origins of electrical breakdown in liquid dielectrics. Streamers are conductive structures that form in regions of liquid dielectrics that are over-stressed by intense electric fields. Streamers can transform to surface flashovers when they reach any liquid-immersed solid insulation. Surface flashovers usually propagate faster and further than streamers in similar electric field intensity. Charge generation and transport is crucially important in liquid dielectric breakdown, since without the presence of the electric charge and its ability to migrate in the liquid dielectric volume and on the interface of liquid/solid dielectrics, streamers and surface flashovers are unable to develop. In this thesis, we develop a finite element method transport model in one, two and threedimensional geometries to help understand the complicated dynamics of electric charge transport and streamer breakdown in liquid dielectrics. This electrohydrodynamic model clarifies many of the mechanisms behind streamer/surface flashover formation, propagation and branching in typical liquid/solid dielectric composite systems. Several key mechanisms have been identified and added to the transport model of streamers, such as effects of electric field intensity on the ionization potential of liquid dielectric molecules and electron velocity saturation, which make the modeling results more realistic. In addition to improving the understanding of electrical breakdown physics in liquid-based insulation systems, a significant effort is made throughout this thesis research to enhance the stability, convergence, speed and accuracy of the model, making it a convenient and reliable tool for designing high voltage components that contain pure liquid dielectrics, nanofluids and liquid immersed insulation systems. This model, for the first time, is able to treat any given electrode shape and gap distance as well as any applied voltage waveform with accurate results, which provides a convenient preliminary way to verify the performance of an insulation system in terms of breakdown voltage, time to breakdown, electric field intensity distribution and ionization level. The model precision is validated through experimental records, analytical solutions and alternative modeling approaches wherever available. Specifically, we verify our one-dimensional numerical results with exact analytical solutions, and our two and three-dimensional modeling results with experimental data found in the literature or provided by ABB Corporate Research, Sweden. The streamer initiation voltages, number of streamer branches, breakdown voltages and currents are in excellent agreement with the experimental data compared to the prior theoretical research on liquid breakdown physics. Identical results obtained using a finite volume method also confirm the correctness of the finite element approach used in this thesis. The presented model can be employed to search for novel configurations of liquid immersed insulation systems including nanofluids and liquid/solid composite systems.

Available in PDF, EPUB and Kindle. Book excerpt: While the standard solid state topics are covered, the basic ones often have more detailed derivations than is customary (with an empasis on crystalline solids). Several recent topics are introduced, as are some subjects normally included only in condensed matter physics. Lattice vibrations, electrons, interactions, and spin effects (mostly in magnetism) are discussed the most comprehensively. Many problems are included whose level is from "fill in the steps" to long and challenging, and the text is equipped with references and several comments about experiments with figures and tables.
