چکیده:

The increasing need to guarantee the highest possible endurance capability of EHV lines conductors strung for best economics require efficient Aeolian vibration damping devices. Four-resonant non linear STOCKBRIDGE dampers give the best answer in terms of Aeolian vibration damping efficiency to installed cost ratio. Two type testing methods are exposed :
– the first performed on a shaker to evaluate the damper dynamic response followed by an estimation of the bending stresses induced in the protected conductor,
– the second carried out on a reduced span length in an indoor laboratory.
