An energized 500 kV transmission line in Oregon was used by the Bonneville Power Administration to measure the response of conductors in high winds. The conductor spans on two sides of the instrumented tower were 252 and 450 meters. Three conductors were supported at the tower through load cells and swing angle sensors to measure responses. Simultaneous measurement of wind speed, wind direction and conductor response constituted field data. A total of twenty-three records, each of 12-minute duration, were obtained. Statistical analysis of data yields effective force coefficient, resonant response and aerodynamic damping of the conductors. Results obtained from field measured data have large scatter.
