Abstract-This paper deals with an analytical solution of the time domain Pocklington equation for a straight thin wire of finite length, buried in a lossy half-space and excited via the electromagnetic pulse (EMP) excitation. Presence of the earth-air interface is taken into account via the simplified reflection coefficient arising from the Modified Image Theory (MIT). The analytical solution is carried out using the Laplace transform and the Cauchy residue theorem. The EMP excitation is treated via numerical convolution. The obtained analytical results are compared to those calculated using the numerical solution of the frequency domain Pocklington equation combined with the Inverse Fast Fourier Transform (IFFT).

“…On the other hand, they are extremely vulnerable to lightning strikes due to their special shape and isolated locations mainly in high altitude areas. Analysis of grounding systems can be undertaken by the aid of the transmission line model (TLM) [1][2][3] or the full wave model, also referred to as the antenna model (AM) [4][5][6]. The latter is considered to be the rigorous one.…”

The analysis of a horizontal grounding electrode has been carried out using the set of generalized telegrapher's equations. The integro-differential relationships arising from the full wave model are numerically handled via the GalerkinBubnov scheme of the Indirect Boundary Element Method (GB-IBEM). Some illustrative numerical results for the current and voltage induced along the horizontal electrode are given in the paper.

“…When a nonlinear behavior of the grounding electrode due to soil ionization is modeled using nonlinear TL model, possibilities are to use an analytic solution [1] or to use a number of series connected p-circuits [2,3], both combined with iteration process. Corona effect studies on overhead TL can be based on the finite difference method solution [4] or to use the method of characteristics [5].…”

SUMMARYThe aim of the paper is to present a numerical procedure based on the finite element method (FEM) in the time domain when modeling electromagnetic transients in a single nonlinear electrical network. It presents an extension to the FE time domain model used to analyze electromagnetic transients in linear networks. Based on the Newton-Raphson method for FEM analysis and the generalized trapezoidal rule for time integration a novel numerical procedure for the computation of electromagnetic transients in nonlinear circuits/networks is obtained.
