✦ Synopsis

In recognition of the random character of Aeolian vibrations of overhead conductors, statistical methods are used for the acquisition and reduction of experimental data. The ensemble mean-square values and the distributions of peak values are emphasized in particular. An analytical model of the Aeolian vibrations of a conductor is proposed, based on the theory of narrow frequency bands of random noise. This model serves as a basis for rationalizing the data acquisition and reduction procedures and formulating the mean energy stored, the mean power dissipated and the mean loss factors. A method derived from this model is proposed for the acquisition of data on Aeolian power over a wide range of conditions including different intensities of wind turbulence. This, together with the dynamic properties of a given conductor, should allow consistent predictions of Aeolian vibration levels.
