Gas insulated substations Comprehensive reference covering all aspects of gas insulated substations including basic principles technology use & application design specification testing and ownership issuesThis book provides an overview on the particular development steps of gas insulated high voltage switchgear and is based on the information given with the editors tutorial. The theory is kept low only as much as it is needed to understand gas insulated technology with the main focus of the book being on delivering practical application knowledge. It discusses some introductory and advanced aspects in the meaning of applications.The start of the book presents the theory of Gas Insulated Technology and outlines reliability design safety grounding and bonding and factors for choosing GIS. The third chapter presents the technology covering the following in detail: manufacturing specification instrument transformers Gas Insulated Bus and the assembly process. Next the book goes into control and monitoring which covers local control cabinet bay controller control schemes and digital communication. Testing is explained in the middle of the book before installation and energization. Importantly operation and maintenance is discussed. This chapter includes information on repair extensions retrofit or upgrade and overloading. Finally applications are covered along with concepts of layout typical layouts mixed technology substations and then other topics such as life cycle assessment environmental impact and project management. A one stop complete reference text on gas insulated substations (GIS) large capacity and long distance electricity transmission which are of increasing importance in the power industry today Details advanced and basic material accessible for both existing GIS users and those planning to adopt the technology Discusses both the practical and theoretical aspects of GIS Written by acknowledged GIS experts who have been involved in the development of the technology from the start
