ABSTRACT:
A method and device for removing ice from overhead conductors of a bundle of conductors or preventing an accumulation of ice on these conductors. The method includes forcing the entire current load of the line in one or a portion of the conductors, the excessive power dissipated in this manner de-ices the conductor by Joule heating. The method is repeated for different conductors of the bundle until they have all been de-iced or for the entire duration of an ice storm. Electric power units are provided on each conductor to control the current circulation as needed, and a command module controls the entire system. Conducting elements are provided at the beginning and at the end of the line to allow a distribution of the current as needed.
