The characteristic parameters of the lightning electromagnetic pulse (LEMP) current have been investigated for many years on the basis of the isolation coordination by scientists studying in the field of electricity and physics. The necessity of studying in this area has arisen in order to protect the electrical and electronic equipment inside the power transmission lines and electrical installations against the harmful effects of the harmonic current of the lightning electromagnetic pulse. In this study, the over-voltages, which occur due to the lightning electromagnetic wave strikes on the pylons, were investigated with the Alternative Transient Program (ATP). The Heidler function is used to simulate the LEMP model. Analyzes of the over-voltages that occur as a result of the lightning strike to the protection conductor on the top of a grounded pole or one of the pole conductors of the pylon are carried out. Moreover, high voltage, electric field and magnetic field changes in the environment where the lightning electromagnetic pulse strikes are analyzed numerically in MATLAB using Rusk equations and compared with ATP simulation results.
