“…J.J. Ratkowski [16] In addition, the airfoil critical orientation must exist over a major portion of the span otherwise the atmospheric forces will act to damp the galloping motion in the portion of the span that is not critically oriented. He further explained in another paper [17] using an energy method that he found three general types of galloping, each exists due to different conditions which start the galloping.…”

Theoretical study and phenomenal examination have been ongoing for many years; however, some electric power companies still have instantaneous power failure due to galloping. This study differs from others in that nonlinear three‐dimensional simultaneous equations of conductor movement can be solved directly using numerical calculation. Fundamental characteristics of galloping can be ascertained by changing calculation parameters variously. This time, a method is used in which bundle conductors are changed equivalently to single conductor. It is also clarified that unstable domain becomes wider when rotational movement of conductor occurs.
