The first chapter of this book tells about Modern Meteorology and Atmospheric Icing that can help engineers and designers to better plan power-line routes or situate wind-turbine parks, through better understanding of weather patterns in a given region. The book also tell in next chapter about Statistical Analysis of Icing Event Data for Transmission Line Design Purposes. The authors of this book describe how data from ice storms is gathered by monitoring systems and is used to establish design parameters for lines crossing regions where severe icing events occur. The third chapter is Numerical Modelling of Icing on Power Network Equipment. It discusses how numerical icing models have become such essential tools in the field, as they use observations and measurements to produce simulations of extreme events that may be beyond our empirical experience. This is followed by Wet Snow Accretion on Overhead Lines, which deals with the physics of snow, particularly wet snow accretion on power line conductors, both in the wind tunnel and under natural conditions, in terms of overload hazards. Effects of Ice and Snow on the Dynamics of Transmission Line Conductors is explained in the following chapter which deals with the reliability and lifespan of iced conductors under such stresses as galloping, or wind-induced oscillations and aeolian vibrations, the mechanisms involved, and prevention methods. Effects of Ice and Snow on the Electrical Performance of Power Network Insulators is a detailed look at the electrical performance of line and station insulators covered with ice or snow; it takes us through the modelling, testing, design and mitigation stages. The last chapter, Design of Transmission Lines for Atmospheric Icing, is the ABC of structural design for adverse winter conditions – a thorough description of transmission line design, taking into account snow and ice overloads and other extreme weather effects. Thi book is a comprehensive and exhaustive examination of atmospheric icing and is intended and useful tool for utilities, first and foremost, looking to implement or adjust company-wide design policies with regard to severe wind and ice loads on overhead lines, and utility maintenance engineers and operators, who try to balance the costs and benefits of mitigation options when addressing specific icing problems. It is also for professionals who are involved with the IEEE Power Engineering Society (PES), CIGRE and IEC, in their efforts to develop international icing standards, will find the book useful in their detailed studies of specific areas of research and consulting.
