Introduction To Instrument Transformers

Dramatic power outages in North America, and the threat of a similar crisis in Europe, have made the planning and maintenance of the electrical power grid a newsworthy topic. Most books on transmission and distribution electrical engineering are student texts that focus on theory, brief overviews, or specialized monographs. Colin Bayliss and Brian Hardy have produced a unique and comprehensive handbook aimed squarely at the engineers and planners involved in all aspects of getting electricity from the power plant to the user via the power grid. The resulting book is an essential read, and a hard-working reference for all engineers, technicians, managers and planners involved in electricity utilities, and related areas such as generation, and industrial electricity usage. * An essential read and hard*working ref

Combining select chapters from Grigsby's standard-setting The Electric Power Engineering Handbook with several chapters not found in the original work, Electric Power Transformer Engineering became widely popular for its comprehensive, tutorial-style treatment of the theory, design, analysis, operation, and protection of power transformers. For its

"Instrument Transformers" serves as an indispensable guide for electrical engineers and professionals navigating the complexities of measuring high-voltage currents and potentials. In the realm of electrical engineering, direct measurement of voltages and currents in the "kilo" or "mega" range presents significant challenges, not only due to the sheer magnitude of these values but also because of the safety and accuracy concerns involved. Instrument transformers, including current transformers (CTs), potential transformers (PTs), and capacitive voltage transformers (CVTs), emerge as critical tools in mitigating these challenges, enabling precise and safe measurements by converting high values to more manageable levels. This book delves into the crucial aspects of instrument transformers, offering a comprehensive exploration of their design, operation, and application within electrical systems. By providing detailed technical data and insights, it aims to equip readers with the knowledge needed to effectively utilize these transformers in real-world settings. The focus extends beyond theoretical understanding, emphasizing practical solutions to the technical problems that electrical engineers frequently encounter in their fieldwork. Whether it's for performance evaluation, quality analysis, or the smooth and safe operation of electrical systems, "Instrument Transformers" stands as a vital resource. It promises not only to enlighten its readers on the fundamental principles and applications of instrument transformers but also to guide them through troubleshooting and problem-solving processes, ensuring efficiency and safety in electrical measurement and control operations.

Existing instrument transformer technologies as well as new measuring principles for current and voltage measurement are described in this book. The properties of conventional current and voltage transformer as well as the dimensioning are discussed in details out of the long experience of the authors. Especially the dielectric dimensioning and the used materials are discussed. Beside this an overview over new modern measuring principles is given and the technology of low-power instrument transformer, and RC-dividers are shown.
