Uncertainties of environmental and physical parameters of outdoor power transmission lines are rarely known, though they are very critical in planning, operation and line uncertainty modeling for power utilities. Several approaches have been previously used to predict such parameters in wide transmission corridors. Transmission line uncertainty modeling can be challenging since it is based on the assumption of the unknown limits. This paper characterizes and evaluates these approaches. After comparative study, the interval mathematical approach is shown to be more versatile than the rest of the techniques because of the ability to stretch the unknown variable while bounded.
