00925njm 22002777a 4500 dc González Prunera, Sergio author 2012 This work deals with the health monitoring of overhead power lines conductor’s technologies. In particular, the scope of the present Master’s Thesis is to develop a method to catch the damping from a given register of data. The data represents the vibration of overhead power line conductor. The method tested is the Prony’s Method. The thesis is structured in two main blocks. The first is composed by chapters from 1 to 4. The information included is a state of the art of the current technologies applied in ambient vibration monitoring of bridges, suggesting how to apply them in cable monitoring (chapter 1), an introduction to the Aeolian vibration phenomenon (chapter 2), a brief introduction to the basic theoretical bases of the vibration movement (chapter 3) and, finally, a chapter dedicated exclusively to the self-damping in conductors, explaining what is it, and how to measure it (in laboratories) and to evaluate it (chapter 4). The second block is related to the investigations done. It is composed by chapters from 5 to 11. It includes the description of the data used (chapter 5), a complete explanation of the preprocessing and processing of the data (chapters 6, 7 and 8), the presentation of the results obtained (chapter 9), some conclusions (chapter 10) and recommendations for further work (chapter 11). The main conclusion is that the Prony’s Method is not suitable to determine the self-damping coefficient of the vibration data.
