Abstract

Freezing rainstorms coupled with moderate winds have often been observed to cause telephone lines and power transmission cables to begin bouncing up and down. This slow frequency high amplitude oscillation, or galloping as it is sometimes called, can build up to large amplitudes before the oscillation either damps out or persists at some constant amplitude. It has been reported by Edwards and Livingston [1] that the amplitude of galloping on transmission lines has been as large as forty feet. Galloping oscillations occur at relatively low frequencies; from .1 to 1 Hz. [1] near the natural frequency of the suspended cable.
