Abstract

This paper investigates a suitable model for a power line conductor to explore its free vibration characteristics. For this, we compare the Euler–Bernoulli beam model of the conductor against the string model of the conductor via experimental and analytical vibration analyses. The effects of conductor parameters such as flexural rigidity, diameter, length, and tension on the natural frequencies of different modes are explored through parametric studies. We observe that the Euler–Bernoulli beam model of the conductor is a more realistic approach to examining the conductor's free vibration characteristics as compared to a string model.
