摘要：
This paper investigates the influence of considering frequency-dependent ground parameters in the calculation of lightning transients on a two-phase distribution line including the presence of branches. The analysis is focused on propagation effects along the line. It is shown that the influence of frequency dependent ground parameters is only remarkable if a poorly conducting ground is considered. It is also shown that the presence of line branches is likely to reduce the relative importance of considering the frequency variation of the ground parameters in the calculation of lightning transients.
