Sažetak
Transient behavior of transmission towers and associated grounding systems exposed to a lightning surge current having a double exponential pulse waveshape is investigated and analyzed. Frequency domain solutions for electromagnetic fields generated by the network of overhead and buried cylindrical conductors subjected to the thin-wire approximation are derived based on the field theory approach. Once the scalar potentials and electromagnetic fields in the vincinity of the tower have been computed at selected frequencies, the time domain response is obtained using the inverse Fast Fourier Transform. Simulation models are obtained by the use of HIFREQ and FFTSES modules of the CDEGS software package.
