Application study on one-dimensional partial element equivalent circuits to lightning current distribution on surface structure

The Manhattan representation of structures is occasionally insufficient for obtaining lightning current distribution using partial element equivalent circuits (PEECs). Therefore, a method for representing a structure using thin wires was studied, and the PEEC was solved using the θ method. This method was applied to different examples, and the results were compared with those obtained using the finite integration technique. An experiment was conducted to verify the developed method. The method was shown to be effective in simulating the current distribution on surface structures. This is of great significance in the design of lightning-protection systems.
