Abstract :
Estimates of maximum amplitudes of conductor galloping are needed in order to determine appropriate phase-to-phase clearances on overhead lines. A new method for computing these estimates is presented. The method gives estimates of the amplitude and frequency of galloping limit cycles along with the wind speed at which they occur. These features make the method useful as a design guide and also allow it to be used to gain further insight into he mechanisms of conductor galloping.
