The book provides power engineers with information on the best use of GIL and its technical, economical and environmental impact. It presents specific information on GIL technology for future applications used to solve power transmission problems. The book opens with an overview chapter and then goes on to describe the history of the topic in detail. The third chapter covers the technology, evaluating design, insulating systems, gas insulators, and assembly with welding technology and on site work. It also looks at corrosion protection and monitoring. The next chapter analyses systems and networks, covering transmission losses, autoclosure operation and aging. The important subject of environmental impact is decribed in Chapter 6. Electromagnetical fields, gas structures, thermal aspects, and lifecycle assessment are investigated. Finally, economical aspects are covered. Cost drivers are identiified and measures are explained to show readers how to keep costs down. The book ends with a chapter on applications, illustrating typical fields of application through real projects that the author has himself worked on.

Hermann Josef Koch, Principle Expert,  Power Transmission, Siemens, Germany
Mr Koch currently works in the field of high voltage switchgear and high voltage transmission lines with Siemens in Germany. He became Principal Expert after over-seeing the installation of the first second generation GIL (gas insulated transmission lines) in Geneva, Switzerland in 2001. Since then he has worked on many projects with Siemens.
Mr Koch created a successful tutorial Gas Insulated Substations with the IEEE PES Substations Committee, which has been presented in more than twenty countries including the USA, Canada, South America and India. He has published 149 articles and written chapters in two leading books on GIL, The Wiley Encyclopedia of Electrical and Electronics Engineering and the Substation Handbook (CRC Press).
