Abstract
A study of the sudden failure of conductors iv overhead transmission lines has been developed, using field data. It is found that the failure can be attributed to the excessive vibration of conductors under the stochastic wind excitation. By analyzing the field data, the maximum amplitude of vibration, and consequently the dynamic stress in the conductor, is calculated, and conductor’s life is estimated to be less than 20 years for several sites.In this work, mass-damper ”which acts as dynamic absorber” is introduced to reduce the vibration of overhead transmission lines, such that the sudden failure of the conductors can be avoided. The effect of clamping massdamper on the vibration of the conductor, and consequently on the dynamic stresses, has been investigated. The estimated life of the conductor is found to increase to more than 150 years by the implementation of this scheme.
