Research on Transmission Line Vibration Based on the Dynamic Response of Strain in Straight Tower Cross Arm Structure Under Wind–Ice Loads

Energies
Under ice and wind loads, transmission conductors undergo varying degrees of displacement, with larger displacements potentially causing direct damage to the transmission tower–line system and posing serious safety hazards.

Conductor Galloping Prediction on Imbalanced Datasets: SVM with Smart Sampling

, 2019
Conductor galloping is the high-amplitude, low-frequency oscillation of overhead power lines due to wind. Such movements may lead to severe damages to transmission lines, and hence pose significant risks to the power system operation. In this paper, we target to design a prediction framework for conductor galloping. The difficulty comes from imbalanced

A note on galloping conductors

, 1950
The results of wind tunnel tests on a series of two-dimensional models simulating circular cables with various ice formations are presented. The stability of small oscillations of a transmission line in a steady wind normal to the span is considered, and the wind tunnel results are used to calculate the behaviour of a cable with D shaped fairings.

Aerodynamic and Vibration Characteristics of Iced Power Transmission Conductors in a Nonuniform Wind Field Based on Unsteady Theory

Energies
To study the aerodynamic and vibration characteristics of iced conductors under the influence of wind fluctuations, a harmonic superposition method is used to simulate nonuniform wind speeds.
