In this sense, a computational code is implemented in MATLAB based on said methodology to simulate certain cases related to direct and indirect impacts of lightning on towers and transmission lines.
(ABC-Liao) to obtain the magnitudes of the irradiated electric and magnetic fields as well as the coupling of the electromagnetic field with the line by means of the thin conductor model (TWM) to obtain the magnitudes of the voltage and current increases that are generated. The methodology consists in the joint application of the electromagnetic model of the Maxwell-Heaviside equations to describe the propagation of electromagnetic wave generated by the beam, the finite difference in time domain (FDTD) method with Liao absorbing boundary conditions. The purpose of this paper is to present a model consisting of a methodology based on Computational Electromagnetics and Vector Analysis, developed with the purpose of providing solutions to the problem of the study of electromagnetic transients due to atmospheric discharges or rays on transmission lines.
