PHENOMENA of vibration in transmission lines due to the action of a transverse wind are encountered most frequently at moderate wind velocities (about 5 miles per hr.) and are characterized by rather high frequencies (5 to 15 cycles per sec.) and small amplitudes (up to a few cable diameters). This type of vibration is caused by the “Karman” vortices forming behind the wire and is well understood.
