Study on Impulse Current Dispersal and Structure Optimization of Grounding Electrode Structure of Tower

In this paper, a simulation model for soil nonlinear ionization is established, and the actual grounding electrode of the project is studied. Results show that for radial grounding electrodes, the horizontal ray conductor has better current dispersal than the middle conductor. Therefore, when improving the horizontal radiating grounding structure, short conductors should be added to the horizontal ray conductors. According to the impulse current dispersal regularity, two improved methods are proposed. After simulation, the improved grounding resistance is getting smaller, so that the improvement scheme is correct. Finally, two improved methods are applied to the engineering grounding electrode, and the potential and grounding resistance of improved grounding electrode are all reduced, so the improved method is effective.
