Wind Tunnel Measurements of the Power Imparted to a Model of a Vibrating Conductor

Abstract

Predicting the severity of aeolian vibration of overhead conductors requires knowledge of the damping in the span and of the power that the wind can supply to it. There is considerable dispersion in the published data on wind power input. New measurements were made, using a novel test arrangement, in an effort to develop more reliable information. The tests covered a broad range of wind speeds, above and below that at which power input is greatest, to lay a basis for development of methods for dealing with the effects of turbulence in natural winds. Correlation of the new results with previous data is reviewed in depth.
