On the Transient Response and the Frequency Analysis of Transmission Line Towers

Figure 6

The voltage at the tower top 𝑣_𝑇(𝑡) resulting from applying the suggested approach due to a lightening current surge of one Dirac function, that is, 𝑖_𝑠(𝑡)=𝛿(𝑡). The source internal resistance 𝑅_𝑖 was assumed infinity. Number of sections 𝑁=25 (100000 divisions = 10µs).
