Applying the finite element method to analyze predischarge lightning rods

In this paper, the finite element method is applied for analyzing 4 types of lightning rods in order to select the optimal lightning rod configuration. First, software is used to calculate the 2D protective coverage of different lighting rods, and 4 kinds of typical lightning rods are simulated in different conditions. The analyzed results are then applied for the selection of the optimal lighting rod and the frame of the lighting rod. The analyzed results would be useful for electrical engineers to design lightning rods that offer the most effective lighting protection; the simulated results are also useful for the optimal location selection of lightning rods.

It is suggested that a lightning rod with a disk radius of 8.5 cm and a terminal radius of 1.7 cm would generate the best performance. Among the 4 studied types of lightning rods, lightning rod 1 required fewer materials and lower costs.
