A procedure is proposed for calculating the parameters characterizing the transfer function of an actual vibration damper for overhead transmission line conductors, based on the preliminary determination of an ideal target transfer function derived from energetic considerations. The procedure involves choosing and minimizing a suitable performance index that characterizes the distance between the two transfer functions. An example of application is presented for a particular type of damper.
