Utilization of reduced models for the analysis of lightning induced overvoltages on overhead lines

This paper deals with the application of the scale model technique to the analysis of lightning induced voltages on overhead power distribution lines. The paper first describes, briefly, the main methods for evaluating lightning transients on power lines. It then presents the basis for the utilization of reduced models and the scale factors for the most important quantities. Finally, examples are shown that illustrate the usefulness of the technique for the validation of theoretical models and relevant computer codes, as well as for investigations involving complex situations.
