Micro-wind vibration tubular busbar

Supporting type tubular busbars often encounter wind-induced vibration problems during long-term service in the field. Numerical simulation methods are used to analyze the wind vibration characteristics of the supported tubular busbar and the influence of damping on. The article presents an analysis of the vibrations of tubular rigid busbar located at a power station. The analysed case concerns a real-life situation involving wind acting on a circular cross-section of the busbar—considered aerodynamically stable—and on an asymmetrically iced cross-section. There are instances, however, when bus damping with conductor cable is not a cost-effectiv solution. But this cheap method is not satisfa...
