GAS INSULATED SUBSTATIONS An essential reference guide to gas-insulated substations The second edition of Gas Insulated Substations (GIS) is an all-inclusive reference guide to gas insulated substations (GIS) and its advanced technologies. Updated to the latest technical developments and applications, the guide covers basic physics of gas insulated systems, SF6 insulating gas and its alternatives, safety aspects and factors to choose GIS. GIS technology, its modular structure, control and monitoring systems, testing, installation rules and guidelines for operation, specification, and maintenance. Detailed information on various types for GIS, with 14 reference project explanations and three extensive case studies give information for the best solutions of practical applications. Special solutions using mobile substations concepts, mixed technology switchgear (MTS) with air and gas insulated technology, underground substations, and the use of special GIS substation buildings e.g., shopping centers, parking lots, city parks, business complexes’ or subway stations are explained. Future developments of GIS technology are shown for the next steps in alternatives to SF6, low power instrument transformers, and digitalization of substations. A new chapter explains advanced technologies applied to GIS projects which cover the following; environmental issues for the substation permission process, insulation coordination studies for the network requirements including very fast transients, project scope development, risk-based asset management, health and safety impact, electromagnetic fields, SF6 decomposition byproducts and condition assessment. Disruptive development steps in gas insulated substations technologies are also covered in this second edition. Vacuum breaking and switching technology for rated voltages of up to 500 kV is explained in detail with its physical background. Principle function and possible implementation of low power instrument transformers (LPIT) are explained and examples of applications are given. The principles of digital twin for gas insulated substations (GIS) and gas insulated transmission lines (GIL) are explained in theory and project applications show the practical use and advantage. The wide and fast-growing technical field of offshore GIS applications for AC and DC is explained on many examples and gives information on special requirements when getting offshore. Theoretical requirements on DC gas insulated systems, methods of testing, prototype installation tests, modular design features, and advantages in applications are given. Finally, impact and advantages of digital substations using GIS are explained. Key features: Written by leading GIS experts involved in development and project applications Discusses practical and theoretical aspects Detailed material of GIS for new and experienced GIS users, and project planners Invaluable guide to practicing electrical, mechanical and civil engineers as well as third- and fourth-year electric power engineering students

In the past, the teaching of electricity and electronics has more often than not been carried out from a theoretical and often highly academic standpoint. Fundamentals and basic concepts have often been presented with no indication of their practical appli cations, and all too frequently they have been illustrated by artificially contrived laboratory experiments bearing little relationship to the outside world. The course comes in the form of fourteen fairly open-ended constructional experiments or projects. Each experiment has associated with it a construction exercise and an explanation. The basic idea behind this dual presentation is that the student can embark on each circuit following only the briefest possible instructions and that an open-ended approach is thereby not prejudiced by an initial lengthy encounter with the theory behind the project; this being a sure way to dampen enthusiasm at the outset. As the investigation progresses, questions inevitably arise. Descriptions of the phenomena encountered in the experiments are therefore given in the explanations. Although these were originally intended to be for the teacher's guidance they have been found, in fact, to be quite suitable for use by the student. In the explanations mathematics has been eliminated wherever possible, mechanistic descriptions of phenomena being preferred in all cases. Stress is thereby placed on concepts rather than on mere algebraic relationships. It is hoped that students of weak mathematical background will, as a result, not be prevented from following the explanations and deriving some benefit from these.

This is the eBook of the printed book and may not include any media, website access codes, or print supplements that may come packaged with the bound book. This full-color text offers a clear, complete introduction and detailed reference for creating 3D models and 2D documentation drawings. Building on its reputation as a trusted reference, this edition expands on the role that 3D CAD databases now play in design and documentation. Superbly integrated illustrations, text, step-by-step instructions, and navigation make it easier than ever to master key skills and knowledge. Throughout, the authors demonstrate 3D and 2D drawing skills and CAD usage in real-world work practice in today’s leading disciplines. They combine strong technical detail, real-world examples, and current standards, materials, industries, and processes–all in a format that is efficient, colorful, and visual. Features: Splash Spread: Appealing chapter opener provides context and motivation. References and Web Links: Useful weblinks and standards provided upfront in each chapter. Understanding Section: Foundational introductions, tabbed for easy navigation, outline each topic’s importance, use, visualization tips, and theory. Detail Section: Detailed, well-tested explanations of drawing techniques, variations, and examples–organized into quick-read sections, numbered for easy reference. CAD at Work Section: Breakout pages offer tips on generating drawings from 2D or 3D models. Portfolio Section: Examples of finished drawings show how techniques are applied in the real world. Key Words: Italicized on first reference, summarized after each chapter. Chapter: Summaries and Review Questions: Efficiently reinforce learning. Exercises: Outstanding problem sets with updated exercises, including parts, assembly drawings from CAD models, sketching problems, and orthographic projections.
