Gas-insulated transmission lines (GIL) is an established high voltage technology used when environmental or structural considerations restrict the use of overhead transmission lines. With an overview on the technical, economical and environmental impact and power system implications of GIL, this guide provides a complete understanding of its physical design, features and advantages. The author illustrates how to evaluate when GIL would be the best solution during the planning sequence and how to apply GIL in the electricity power network. Other key features include: operation and maintenance requirements with information on repair processes, duration, and different monitoring systems enabling the achievement of reliable and safe operation;a wide variety of realized applications from across the world over the past 35 years, illustrating typical fields of application through descriptions of real projects that the author has worked on; andfuture application possibilities in a smart transmission network, used for solving power transmission problems.This is an essential reference for engineers involved in planning and executing bulk power transmission projects overground, in tunnels or buried. It offers a concise summary of all areas of the subject and is the perfect aid for utility power engineers, consulting engineers and manufacturers worldwide.

Practical Guide to International Standardization for Electrical Engineering provides a comprehensive guide to the purpose of standards organizations, their relationship to product development and how to use the standardization process for cost-effective new product launch. It covers major standardization organizations in the field of Electrical Engineering offering a general overview of the varying structures of national standardization organizations, their goals and targets.Key questions for standardization are answered giving the reader guidance on how to use national and international standards in the electrical business. When shall the company start to enter standardization? How to evaluate the standardization in relationship to the market success? What are the interactions of innovations and market access? What is the cost of standardization? What are the gains for our experts in standardization?Key features: Provides guidance on how to use national and international standards in the electrical business.Global active standardization bodies featured include IEEE, IEC and CIGRE as well as regional organizations like CENELEC for Europe, SAC for China, DKE for Germany, and ANSI for USA.Case studies demonstrate how standardization affects the business and how it may block or open markets.Explains the multiple connections and influences between the different standardization organizations on international, regional or national levels and regulatory impact to the standardization processes.Two detailed focused case studies, one on Smart Grid and one on Electro-Mobility, show the influence and the work of international standardization. The case studies explain how innovative technical developments are promoted by standards and what are the roles of standardization organizations are.A valuable reference for electrical engineers, designers, developers, test engineers, sales engineers, marketing engineers and users of electrical equipment as well as authorities and business planners to use and work with standards.

GAS INSULATED SUBSTATIONSAn essential reference guide to gas-insulated substationsThe 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 applicationsDiscusses practical and theoretical aspectsDetailed material of GIS for new and experienced GIS users, and project plannersInvaluable guide to practicing electrical, mechanical and civil engineers as well as third- and fourth-year electric power engineering students
