Comprehensive reference covering all aspects of gas insulated substations including basic principles, technology, use & application, design, specification, testing and ownership issues

This book provides an overview on the particular development steps of gas insulated high-voltage switchgear, and is based on the information given with the editor's 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

1.1 General

This book is based on the tutorial and panel sessions presented by the experts of gas insulated substations in the working group K2 of the IEEE Substations Committee. Gas insulated substations (GIS) were invented in the early 1960s with the first projects in the mid 1960s in the United States and Europe. In thousands of installed bays of GIS today, we can look back to a wide range of experiences gained in very different cases of applications.

The IEEE Substations Committee created GIS Subcommittee K0 more than twenty years ago and since then this subcommittee has continuously worked on standards and guides in the field of GIS technology and application. About twenty standards and guides related to the GIS have been published to-date, with continuous revision work in progress on all documents.

Around the year 2000 the experts of the GIS Subcommittee started to collect information on GIS and developed a tutorial on Gas Insulated Substations (GIS) and Transmission Lines (GIL). This working group is numbered as K2 in the GIS Subcommittee.

1.1.1 Organization

The organization of the Substations Committee has developed over the last decades with the focus on any equipment and systems related to substations. In Figure 1.1 the principal organization of the Substations Committee of today is shown.

In blue, the administrative level shows the chairman as the leader and the legislative administrative subcommittee B0, where all chairmen of the subcommittees of the Substations Committee are voting members. All decisions in the Substations Committee are taken here.

The green boxes are supporters of the chairman to help him carry out all the work by splitting tasks to the vice chairman, secretary, past chairman, standards coordinator, transaction editor, awards nominator, and meeting planner. These functions are elected every two years but can be extended by re-elections.

The actual standards' work is done in the working groups organized by the subcommittees, which cover:

C0:	Data acquisition, processing and control systems with a focus on substation requirements as part of the overall network
D0:	Transmission and distribution substation design for a medium voltage substation in the range of 1 kV up to and including 52 kV and a high voltage substation above 52 kV
E0:	Transmission and distribution of substation operations for medium voltage substations in the range of 1 kV up to and including 52 kV and high voltage substations for above 52 kV
I0:	High voltage power electronics stations for DC equipment above 1.5 kV to be installed in a substation or converter station like AC/DC converters, coils, filters, grounding, and software for control and protection
K0:	Gas insulated substations for AC high voltage equipment above 1 kV of switchgear, disconnectors, and ground switches (GIS) and power transmission (GIL)

The responsibility for the GIS/GIL tutorial is with working group K2. In this working group the content of the tutorial has been worked out and discussed before...
