Written by prominent experts in the field, this book takes an in-depth look at the issues of electrical insulators for icing and polluted environments. It shows:
Engineers and environmental specialists how to carry out appropriate insulator contamination measurements, understand how these readings change with time and weather, and work out how the readings compare with the upper limits set by insulator dimensions in their existing stations
Design engineers how to assess the likely maximum pollution and icing limits at a substation or along an overhead line, and then select insulators that have appropriate withstand margins
Regulators why modest ice accretion at a moderate 0oC temperature on one occasion can qualify as a major reliability event day, while many similar days pass each winter without power system problems
Educators why the ice surface flashover is well behaved compared to the conventional pollution flashover, making it much more suitable for demonstrations, modeling, and analysis
The book is complemented with case studies and design equations to help readers identify the most appropriate insulators, bushings, and maintenance plans for their local conditions. Additionally, readers may download supplemental materials supporting evaluation of local climate and contamination.
Insulators for Icing and Polluted Environments is indispensable reading for any professional who needs reliable electrical supply from networks exposed to sources of wetting and pollution. It also serves as an excellent introduction to the subjects of high-voltage surface flashover, environmental electrochemistry, and insulation coordination for researchers, professors, and students.
"This text provides the essential fundamentals of transmission line design. It is a good blend of fundamental theory with practical design guidelines for overhead transmission lines, providing the basic groundwork for students as well as practicing power engineers, with material generally not found in one convenient book." IEEE Electrical Insultation Magazine
Electrical Design of Overhead Power Transmission Lines discusses everything electrical engineering students and practicing engineers need to know to effectively design overhead power lines. Cowritten by experts in power engineering, this detailed guide addresses component selection and design, current IEEE standards, load-flow analysis, power system stability, statistical risk management of weather-related overhead line failures, insulation, thermal rating, and other essential topics.
