Popis: The ice storm of 1998 in northeastern North America caused much damage to the electrical installations of TransE/spl acute/nergie, the transmission provider in Que/spl acute/bec. Consequently, efforts to mitigate the effects of future ice storms have been deployed. A companion paper describes a project to deploy de-icing strategies over a region afflicted by an ice storm. It relies on a core computation that determines the current magnitudes and application times required to melt the ice off of energized conductors. This paper describes and compares the theory behind three de-icing models for transmission lines. The latter two models are new; they expand on a well-known de-icing computation by adding extra information about the ice buildup and the ice/water transition on the outer and inner surfaces of the ice sleeve, respectively.
