On the Transient Response and the Frequency Analysis of Transmission Line Towers
Figure 5
A comparison between the results of the voltage and the current at the tower top as well as the instantaneous tower input impedance resulting from applying the suggested approach due to a 30 kA double exponential lightening current surge. Numbers of sections are for the plots to the left and for the plots to the right (30000 divisions = 6 µs).
(a) Voltage at the tower top
(b) Current at the tower top
(c) Instantaneous input impedance seen at the tower top
