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.
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).
