Abstract

Wind-induced conductor vibrations may cause serious damage both to the conductors themselves and to the fittings. Given the considerable importance of EHV and UHV lines, such damage and the consequent outages result in significant financial loss. It is therefore fundamental that the right choice should be made as regards damping systems to reduce the vibration amplitudes and to keep stresses on conductors and fittings (spacers, dampers, clamps, etc.) to within acceptable values. This choice is greatly aided by predetermining the vibr~ tory behaviour of the system (conductors, spacers, dampers) through the use of mathematical models and computer programs. This report describes some field tests used in setting up the aforementioned programs. A description is given of the methodologies e~ ployed in the measurement and the subsequent processing of data, dwelling in particular on a system for acquiring and recording data using a minicomputer, which enables most of the quantities recorded to be processed on the spot and in real time. Lastly, the experimental results obtained are compared with those produced with the computer programs.
