Abstract :
This paper presents a probabilistic model for predicting Aeolian vibration response of single overhead conductors. Two different approaches are used to assess safe design tensions. One is based on the conductor fatigue endurance limit and the other is based on linear fatigue damage accumulation associated to each vibration cycle which leads to a certain predicted fatigue life of the conductor. Recently, CIGRE Task Force 22.11.04 made a large use of the calculations made with this model in working out its final recommendations of safe design tensions
