Galloping of overhead transmission lines in gusty wind

To develop galloping suppression devices, it is important to understand the effects of wind turbulence on galloping and to establish an evaluation met hod which takes 'large conductor deformations into account. This paper intr oduces some findings on galloping in gusty wind obtained by numerical simul ation using a model based on the Mogami Test Line of the Tokyo Electric Pow er Co. The equations of motion of the conductor are based on the Lagrangian formulations by Simpson, and they are made discrete in accordance with a f inite element method.
