Calculation of wind loadings on components of overhead lines

The paper describes a procedure for the calculation of wind forces on components of overhead lines. The nature of the terrain in which the line is situated affects the properties of the atmospheric wind incident on the line. The effects of these changes in wind properties on the loading on the components of the line are discussed. Although the method is based on a statistical approach, the calculation procedure has been considerably simplified by presenting the results in terms of coefficients which depend on the type of terrain and the parameters of the line. These coefficients are presented in graphical form. Whenever possible, the effects of parameters which are of secondary importance have been simplified.
