This document shows the comparison of electromagnetic oscillating waveforms of voltage and current during the lighting strike in a coupled HVAC/HVDC transmission line near substation 400kV. The investigations were made for different models of corona effect in the line. As result, the characteristic overvoltage factors were given and more conclusions were presented.
