Abstract

The aeroelastic instability of an ice-covered wire of overhead power transmission lines was investigated. An engineering method for calculating critical wind velocities is proposed. This method makes it possible to define the boundaries of the region of wire galloping of the split phase of a multi-span transmission line. The results that were contained can be used when developing measures to protect overhead power transmission lines from wire galloping.
