The most common technology in the world for the construction of powertransmission over head lines is via suspended conductors attached to towers. As one can easily imagine, these conductors are subjected to vibrations induced by wind. The magnitude of the induced vibrations depends on the cable-wind interaction, but it’s pretty right saying that it becomes more dangerous especially when the line is in open spaces without natural obstacles (e.g. deserts, lakes, plains without woods) due to possible presence of laminar wind. With the scope of reducing the magnitude of this kind of vibrations and protect the line (and the users) from out of service, many type of dampers have been designed during the years.
