Abstract |
This paper describes unique ideas and devices to accurately measure cable tension of ultra high voltage transmission line. The authors developed a manpower exciter named "YUSURU," which is characteriz...ed by light-weight, non-power, and application of bicycle mechanism. In a vibration test, the exciter was used to swing a transmission tower. A sensitive tension meter with the special specification was also employed to measure the cable tension. Based on the data obtained in the test, a numerical analysis was made into the dynamic properties of the transmission tower and line. It was revealed that the Nonlinear analysis result was nearly coincided with the vibration test result.show more
