This paper studies how wind turbine blades react immediately after lightning strikes by analyzing the fast-moving lightning impulse current until it reaches ground. The experimental design consists of horizontal conductors and vertical rods that use two-layered soil models for investigations. The research evaluates vertical rods and horizontal conductors as well as grounding grids when positioned in two-layer soil setups. The non-linear conductance of transmission line modeling (TLM) creates an effective method to simulate grounding systems. The developed model analyzes transient behavior through the implementation of frequency-dependent parameters for soil. The approach for modeling soil ionization includes treating non-linear conductance as a time-dependent factor along with modeling residual resistivity changes. Different combinations of lightning current impulses are used during testing to determine both ground potential rises and system transients while measuring impulse impedance properties of the grounding system. Transient voltage on current feed points of different length of electrodes. Results regarding the impulse impedance of both vertical and horizontal grounding rods appear in the study findings. The model results undergo validation by verifying them against other developed models which displays satisfactory accuracy. The study investigates impulse impedances of vertically and horizontally buried grounding electrodes located in two-layer soil structures whose electrical features change while subjected to a 5 kA peak impulse.
