Periodic and quasiperiodic galloping of a wind-excited tower …

WebGalloping conductors in eastern Idaho around Christmastime 1998. Conductor gallop is the high-amplitude, low-frequency oscillation of overhead power lines due to wind. [1] The movement of the wires occurs most commonly in the vertical plane, although horizontal or rotational motion is also possible. WebThe coupled galloping is characterized by lower amplitude than that of the tower-excited parameter galloping at frequency ratio of ω ¯ 1 / ω ¯ ≈ 2. If frequency ratio of ω ¯ 1 / ω ¯ is within a certain range, the beat galloping phenomenon may occur. The amplitude of the overhead power-line varies with angle of the upper rain-line and ... ch300s リモコン
