Transmission Line Dynamic/Static Structural Testing

A series of full-scale structural static and dynamic tests were erformed to characterize selected properties of a 1200-kV mechanical test line. Prior to the experiment tests, a finite-element analysis of the test tower was conducted. The analytical techniques used to determine the static and dynamic behavior of a transmission tower will provide satisfactory results. Full-scale dynamic testing using the twang excitation technique proved adequate for characterizing the dynamic properties of a transmission line tower and conductor-bundle system. The importance of a pretest computer analysis to aid in experiment design is demonstrated.
