Galloping of electrical lines in wind tunnel facilities
TL;DR: In this paper, a typical eccentric ice shape has been reproduced on a classical stranded overhead line conductor, and the same sample has been suspended in the wind tunnel by springs in order to obtain a system as close as possible to an overhead line (vertical, horizontal and rotational movements are allowed).

On the computation of damped wind-excited vibrations of overhead transmission lines
TL;DR: In this article, the dampers are characterized by means of a 2×2 complex impedance matrix which can be experimentally determined in the laboratory and which includes the effects of the rotatory motion of the clamp.

An Efficient Algorithm for Aeolian Vibration of Single Conductor With Multiple Dampers
TL;DR: In this article, a combination of an impedance transfer technique (ITT) and a forced vibration method (FVM) is proposed for analyzing the Aeolian vibration of a span of a single conductor with multiple dampers.

Ein einfaches Rechenmodell zur Berechnung winderregter Schwingungen an Hochspannungsleitungen mit Dämpfern
TL;DR: In this article, the authors present a Weg eingeschlagen: Dampfungs-and Windleistung werden fur das halbunendlich bzw. unendlich lange Seil berechnet, was infolge des sehr dichten Spektrums der Eigenfrequenzcn des endlichen Seiles zu guten Ergebnissen fuhrt.

Semi-active control of forced oscillations in power transmission lines via optimum tuneable vibration absorbers: With review on linear dynamic aspects
TL;DR: In this article, tuneable vibration absorbers (TVAs) are used to suppress galloping forced vibrations (as a semi-active control approach) using mode summation technique, mathematical model of the hybrid problem including the transmission line and an arbitrary number of absorbers is presented.

Dynamics of stockbridge dampers
TL;DR: In this article, a theoretical analysis of the response characteristics of the Stockbridge dampers is presented, and the experimental results of the analysis have been verified experimentally by treating it as a two-degree-of-freedom system.

Wind tunnel and analytical investigations into the aeroelastic behaviour of bundled conductors
TL;DR: In this article, the conditions for bundle instability were determined for spring-mounted, sectional models in the wind tunnel and the stability boundaries were in good agreement with predicted values from a quasi-steady analysis using measured mean forces.

Determination of the natural frequencies of multiconductor overhead transmission lines
TL;DR: In this paper, stiffness relations for elastic catenary segments and two classes of line spacers are developed to facilitate the frequency and modal analyses of bundled overhead transmission lines, and frequency equations are exemplified for the low frequency oscillation modes of a quadruple catenary with a central flexible spacing element and several natural frequencies and mode shapes determined.
