In this paper, several models of transmission poles, grounding devices and insulators are explained, and their characteristic data are given. A simulation was also performed on the 110 kV DV Postire (Brac)-Stari Grad (Hvar) with appropriate models using ATPDraw (Alternative Transient Program), in which atmospheric discharges were simulated into the top of the transmission line pole and into the phase conductor of the transmission line. It is shown how different lightning currents act on the aforementioned transmission line, and how the voltage on the grounding rod of the transmission line pole depends on the steepness of the lightning current front, as well as on the model of the grounding rod and its configuration. The application of different models of insulators is also discussed, and how they have a significant impact on the phenomenon of reverse jump, its occurrence, the moment of occurrence and the resulting amount of reverse overvoltage. It is also shown how important the geometric position of an individual phase on the pole is and the electromagnetic coupling between the phases on the pole as well as the affected phase according to the protective rope, and how important it is at what moment in time the waveform of the phase voltage is found at the time of the lightning strike on the observed phase.
