Foreword

Though this book on GIS is new, there is quite a long history of how it all began. Initially, and many years back, the technical leads involved in developing GIS industry standards for IEEE assembled a tutorial and presented it at key IEEE meetings and conferences. The popularity with engineers and industry was quite inspiring so the presentations continued. After each occasion, the contributing authors purposely requested helpful feedback from the attendees. This way, the technical material and information flow was improved and finetuned before the next presentation.

After many years, with an effective, polished product in place, the demand arose to re-package this entire knowledge into one valuable book. And so these technical experts under the leadership of Hermann Koch have purposefully congregated and endeavored to assemble this excellent industry reference book for GIS. It is a comprehensive collection which expands on the knowledge and understanding well beyond any other GIS information currently available in industry books.

It begins with basic information on definitions, the physics of GIS, reliability, design principles, safety aspects, decision factors, and SF₆ gas. There is a substantive chapter on the technology of the design, modular components, manufacturing, specification development, instrument transformers and arresters, interfaces, and the bus system alternatives. Then it proceeds into detailed chapters on control and monitoring, testing, installation, and operation and maintenance. This is followed by a chapter providing numerous bus scheme applications, many installation examples, and a case study. This chapter closes with additional information on mobile and mixed technology switchgear (MTS) applications, and future developments. The final chapter addresses other valuable topics including environmental, lifecycle cost analysis, very fast transients, and electromagnetic fields.

This GIS book addresses an impressive amount of involved aspects of the GIS technology, design and application. I am very pleased this book is now available for all the existing power engineers utilizing the advantages of GIS installations, the concerned policymakers and utility leaders, and for students and the generations to come. And I'm also honored to have shared my engineering career with these GIS colleagues who have so generously volunteered their time and energy for the benefit of others.

This book on gas-insulated substations (GIS) is created by a group of expert engineers who have been working to gather in the GIS tutorial working group K2 of the substations committees of the Power and Energy Society (PES) of Institute of Electrical and Electronics Engineers (IEEE). For more than a decade, these experts prepared and presented the GIS tutorial in the USA and around the world. It is time to thank both authors and co-authors for their contributions to the book: Arun Arora, George Becker, John Boggess, Phil Bolin, John Brunke, Ravi Dhara, Arnaud Ficheux, Noboru Fujimoto, Peter Grossmann, Charles L Hand, Richard Jones, Jorge Márquez-Sánchez, James Massura, Venkatesh Minisandram, Pravakar Samanta, Devki Sharma, Dave Solhtalab, Charles L Hand, and Xi Zhu.

Thanks also to these experts who took their time to review and comment on the texts, namely Shawn Lav, Markus Etter, Scott Scharf, Dave Giegel, Ed Crockett, Patrick Fitzgerald, and Linda Zhao.

Another thank-you goes to the contributors to the tutorial over the years who may not be part of the writing team but have added their knowledge and experiences in the tutorial: Roberto Benato, Jerome Blackman, Hugues Bosia, Wolfgang Degen, Mel Hopkins, Daniel Lauzon, Dave Mitchell, Robert Stevenson, and Ryan Stone.

Thank you, John Randolph, for writing this book's Foreword.

To the editing team, warmest thanks go to Angela Dietrich for the text and Ulrich Ballas for the graphics, both from Siemens AG, Germany. Without their great support, this book would not be possible under the dense working load of engineers mentioned above.

Thanks also to the professional work of the editorial and production staff of John Wiley & Sons who were a great help in organizing and setting up the book in a nice looking way.

And of course, I have to thank my wife Edith, my children Christian and Katrin, and their friends Britta and Christopher for giving me the time to work on the book.

May this book be a great help to all engineers active in the gas-insulated substation business and be an enjoyable read or reference to them as well.

Introduction

Authors: Hermann Koch and John Brunke

Reviewers: Phil Bolin, Devki Sharma, Jim Massura, and George Becker

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.
