The increase in demand for electricity and the growing energy density in metropolitan cities have made it necessary to extend the existing high voltage network right up to the consumer. Stepping down the voltage from transmission to the distribution level at the substations located near the actual consumers not only yields economic advantages, but also ensures reliable power supply. Such substations are required to meet a number of severe requirements, including small installation size, effective protection against atmospheric pollution and moisture, noiseless operation, nonexplosive and flame resistant, reduced maintenance, minimal radio interference while providing excellent electric characteristics. Conventional substations using atmospheric air as the main dielectric cannot satisfy these requirements, but totally enclosed substations using sulphur hexafluoride (SF6) gas insulation that are also known as Gas Insulated Substations (GIS). GIS is now in widespread use in the electrical power industry, especially in metropolitan areas. This book will serve as a valuable reference for the novice as well as the expert who needs a wider and detailed scope of coverage within the area of GIS. Gas Insulated Substations provides a comprehensive coverage of a wide range of topics which include: * Introduction to GIS & Properties of SF6 * Layout, Design, Construction, Testing & Maintenance of GIS * Special Problems and Diagnostic Techniques * VFTO Phenomena and its Effects in GIS * Service Experience * Standards Specifications * Future Trends * Extensive References Gas Insulated Substations (GIS) is the first single source for authoritative information on the state of the art in GIS.

Preface The Electrical Engineer's Reference Book was first published in 1945: its original aims, to reflect the state of the art in electrical science and technology, have been kept in view throughout the succeeding decades during which subsequent editions have appeared at regular intervals. Publication of a new edition gives the opportunity to respond to many of the changes occurring in the practice of electrical engineering, reflecting not only the current commercial and environmental concerns of society, but also industrial practice and experience plus academic insights into fundamentals. For this 16th edition, thirtynine chapters are either new, have been extensively rewritten, or augmented and updated with new material. As in earlier editions this wide range of material is brought within the scope of a single volume. To maintain the overall length within the possible bounds some of the older material has been deleted to make way for new text. The organisation of the book has been recast in the following format with the aim of facilitating quick access to information. General Principles (Chapters 1±3) covers basic scientific background material relevant to electrical engineering. It includes chapters on units, mathematics and physical quantities, electrotechnology and network analysis. Materials & Processes (Chapters 4±10) describes the fundamentals and range of materials encountered in electrical engineering in terms of their electromechanical, thermoelectric and electromagnetic properties. Included are chapters on the fundamental properties of materials, conductors and superconductors, semiconductors, insulation, magnetic materials, electroheat and materials processing and welding and soldering. Control (Chapters 11±16) is a largely new section with six chapters on electrical measurement and instruments, industrial instrumentation for process control, classical control systems theory, fundamentals of digital control, microprocessors and programmable controllers. Power Electronics and Drives (Chapters 17±20) reflect the significance of upto 50% of all electrical power passing through semiconductor conversion. The subjects included of greatest importance to industry, particularly those related to the area of electrical variable speed drives, comprise power semiconductor devices, electronic power conversion, electrical machine drives, motors and actuators. Environment (Chapters 21±25) is a new section of particular relevance to current concerns in this area including lighting, environmental control, electromagnetic compatibility, health and safety, and hazardous area technology. Power Generation (Chapters 26±29) sees some rationalisation of contributions to previous editions in the largely mechanical engineering area of prime movers, but with an expanded treatment of the increasingly important topic of alternative energy sources, along with further chapters on alternating current generators and batteries. Transmission and Distribution (Chapters 30±38) is concerned with the methods and equipment involved in the delivery of electric power from the generator to the consumer. It deals with overhead lines, cables, HVDC transmission, power transformers, switchgear, protection, and optical fibres in power systems and aspects of installation with an additional chapter on the nature of electromagnetic transients. Power Systems (Chapters 39±43) gathers together those topics concerned with present day power system planning and power system operation and control, together with aspects of related reactive power plant and FACTS controllers. Chapters are included on electricity economics and trading in the liberalised electricity supply industry now existing in many countries, plus an analysis of the power supply quality necessary for modern industrialised nations. Sectors ofElectricity Use (Chapters 44±49) is a concluding section comprising chapters on the special requirements of agriculture and horticulture, roads, railways, ships, aircraft, and mining with a final chapter providing a preliminary guide to Standards and Certification. Although every effort has been made to cover the scope of electrical engineering, the nature of the subject and the manner in which it is evolving makes it inevitable that improvements and additions are possible and desirable. In order to ensure that the reference information provided remains accurate and relevant, communications from professional engineers are invited and all are given careful consideration in the revision and preparation of new editions of the book. The expert contributions made by all the authors involved and their patience through the editorial process is gratefully acknowledged. M. A. Laughton D. F. Warne 2002

Despite the powerful numerical techniques and graphical user interfaces available in present software tools for power system transients, a lack of reliable tests and conversion procedures generally makes determination of parameters the most challenging part of creating a model. Illustrates Parameter Determination for Real-World Applications Geared toward both students and professionals with at least some basic knowledge of electromagnetic transient analysis, Power System Transients: Parameter Determination summarizes current procedures and techniques for the determination of transient parameters for six basic power components: overhead line, insulated cable, transformer, synchronous machine, surge arrester, and circuit breaker. An expansion on papers published in the IEEE Transactions on Power Delivery, this text helps those using transient simulation tools (e.g., EMTP-like tools) to select the optimal determination method for their particular model, and it addresses commonly encountered problems, including: Lack of information Testing setups and measurements that are not recognized in international standards Insufficient studies to validate models, mainly those used in high-frequency transients Current built-in models that do not cover all requirements Illustrated with case studies, this book provides modeling guidelines for the selection of adequate representations for main components. It discusses how to collect the information needed to obtain model parameters and also reviews procedures for deriving them. Appendices summarize updated techniques for identifying linear systems from frequency responses and review capabilities and limitations of simulation tools. Emphasizing standards, this book is a clear and concise presentation of key aspects in creating an adequate and reliable transient model.
