Abstract

Apart from the problem of wind excitation, the damping also is of specific importance when the problem of mechanical overhead line vibrations is studied. In general, distinction is made between the external damping (for instance, use of vibration dampers, tower influence etc.) and the conductor self-damping. Hence, apart from other information, data of the mechanical conductor self-damping are required for the calculation of the vibration behaviour of a line on planning and for the economical optimization of additional damping means for planned or existing lines. These data are determined by vibration measurements in the lab. This paper describes a measuring method for the determination of conductor selfdamping parameters. The influence of tensile force, vibration amplitude, frequency etc. is depicted by means of the measuring results explaining thus the vibration behaviour of conductor on the overhead line.
