In-plane free vibrations of multi-span transmission lines

Canadian Journal of Civil Engineering, 2019
A theoretical method of in-plane mode and natural frequency of multi-span transmission lines is presented. The main idea is to establish moment balance equations of each insulator string and in-plane vertical motion equation of each span in multi-span section when the effect of conductor inertia component parallel to the chord on the additional ...
