This resource will provide convenient access to ice information for electric utility companies. Using this information, an engineer will be able to identify important characteristics of ice storms for a specific area, when evaluating or designing a power transmission line. Additionally, when developing local design ice load maps, the importance of correlating predicted icing events with historical ice storms makes this information even more valuable for utilities.展开更多
