Learn to correct icing and pollution problems in electrical lineinsulationWritten by prominent experts in the field, this book takes anin-depth look at the issues of electrical insulators for icing andpolluted environments. It shows:* Engineers and environmental specialists how to carry outappropriate insulator contamination measurements, understand howthese readings change with time and weather, and work out how thereadings compare with the upper limits set by insulator dimensionsin their existing stations* Design engineers how to assess the likely maximumpollution and icing limits at a substation or along an overheadline, and then select insulators that have appropriate withstandmargins* Regulators why modest ice accretion at a moderate0¯oC temperature on one occasion can qualify as a majorreliability event day, while many similar days pass each winterwithout power system problems* Educators why the ice surface flashover is well behavedcompared to the conventional pollution flashover, making it muchmore suitable for demonstrations, modeling, and analysisThe book is complemented with case studies and design equationsto help readers identify the most appropriate insulators, bushings,and maintenance plans for their local conditions. Additionally,readers may download supplemental materials supporting evaluationof local climate and contamination.Insulators for Icing and Polluted Environments isindispensable reading for any professional who needs reliableelectrical supply from networks exposed to sources of wetting andpollution. It also serves as an excellent introduction to thesubjects of high-voltage surface flashover, environmentalelectrochemistry, and insulation coordination for researchers,professors, and students.
