Abstract :
Measurements of overhead conductor vibration, caused by Von Karman vortex shedding, were carried out with a new experimental device, developed by the authors, capable of continuous monitoring of acceleration over a wide range of frequency and amplitude. Continuous real-time observations showed the important influence of wind direction and turbulence as well as some divergence in predictions of the Strouhal equation.
