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 rewned 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 sw, then considering static and dynamic mechanical loads, the effects of ice and sw 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.
