Atmospheric Icing of Power Networks

This is a comprehensive book that documents the fundamentals of atmospheric icing and surveys the state of the art in eight chapters, each written by a team of experienced and internationally renowned experts. The treatment is detailed and richly illustrated.

Atmospheric ice takes a wide range of fascinating forms, all beautiful in their own ways but many posing severe risk to the security of overhead networks for electric power, communications and other systems. This comprehensive book documents the fundamentals of atmospheric icing and surveys the state of the art in eight chapters, each written by a team of experienced and internationally renowned experts. The treatment is detailed and richly illustrated. The presentation follows a logical sequence, starting with the icing climate and meteorological conditions, proceeding through development of observations and models of accretion and release of ice and heavy snow, then considering static and dynamic mechanical loads, the effects of ice and snow on electrical insulation, de-icing, ice prevention and mitigation methods. The statistical analysis of icing data and the mathematical and numerical modelling support appropriate mechanical and electrical design processes for icing conditions on overhead lines. Technical specialists, researchers and students in engineering and environmental science will all find value throughout the text.

Although there are many papers and proceedings of specialized conferences on atmospheric icing, none of these distil the results sufficiently to support a line design process Overhead design practitioners presently use a standards-based, deterministic process. Internationally, standards are moving to incorporate probabilistic design methods. The existing experts need to understand where the distributions come from and know how to use them The book has a clear and tight focus, expressed in the title The book has been developed by a strong team of utility and academic experts, jointly participating in a series of bi-annual International Workshop on Atmospheric Icing of Structures (IWAIS), who are motivated to discuss ways to reduce devastation from atmospheric icing at a practical cost
