Wind Tunnel Testing of Iced Conductor Bundles for Galloping Assessment
Background and Motivation Galloping is a large-amplitude, low-frequency aeroelastic instability that may develop on overhead transmission lines under specific combinations of wind conditions and ice accretion. Accurate prediction of galloping requires reliable aerodynamic data, including force coefficients and flutter derivatives, which strongly depend on the geometry of the ice accretion and the conductor bundle configuration.…
