[en] Power line galloping is a large vibration (up to the sag) at very low frequency (fraction of Hz) occuring on power line spans under heavy wind and cold temperature, with ice/snow deposit. Galloping is due to aerodynamic or aeroelastic instability. It may cause dramatic damages on conductor, hardware and towers.
