“…From the point of reduction of vibrations, the location of damper on the cable is significant [5]. The aeolian vibrations were analysed in the paper [8]. Analysis confirms that use of damper do not cause a dissipation of energy and reduction of vibrations in any case.…”

Abstract. In the paper the analysis of vibration of cable with attached damper is performed. Source of vibrations comes from the wind. The level of reduction of vibrations is also analysed. Damper attached to the cable is characterized by mass, stiffness and damping ratio. The paper also presents the equations of motion for the cable with damper, taking into account the initial parameters: cable cross-section and the location of the damper. The analysis is performed in time domain. It is discussed that in real situations the different types of cable vibration due to their amplitudes and frequencies is met: short-term oscillations of high amplitude, caused by a single impulse force, called bouncing cable, low amplitude and low wave length and the high frequency, called aeolian vibration, large oscillation amplitude, long wave length and low frequency, called galloping or dancing cables.

“…The outcomes of these experiments were used to determine conductor input loading. Several models developed by various researchers can be used to determine conductor damping and also the placement of vibration absorbers on the line conductors to curtail the effect of cable mechanical oscillation [23][24][25][26][27]. Based on the various models that have been developed by researchers as indicated in the first and second paragraphs, there is a need to further analyze wind-induced vibration using finite element method (FEM) in MATLAB.…”

Wind-induced vibration affects the performance and structural integrity of high voltage transmission lines. The finite element method (FEM) is employed to investigate windinduced vibration in MATLAB. First, the FEM model was used to develop the equation of motion of the power line conductor. In addition, dampers, conditions for damping, free and forced vibrations of the overhead conductor were considered in the FEM model. Wind-induced experiments were conducted in the laboratory using an actual overhead power conductor. The developed FEM models were simulated in the MATLAB computing environment. The results from the MATLAB simulation, finite element and experimental recordings were compared in order to evaluate the efficacy of models simulated in MATLAB and developed using the FEM.
