Determination of Transmission Line Ampacities by Probability and Numerical Methods

The determination of transmission line ampacities using a statistical approach has been studied at the University of Saskatchewan [6]. This paper describes a method of statistically representing the weather elements by the method of moments and the Pearson family of curves. A digital method of determining the permanent loss of tensile strength due to annealing is also described. These two methods are combined and used to determine the conductor ampacity for selected assumed load patterns.
