The risk of human body electric shock has always been an important issue to be considered in the design of grounding systems. To protect the human body from the risk of electric shock and to facilitate the design of the grounding system. In this paper, we use the Partial-Element-Equivalent-Circuit (PEEC) method to give numerical simulations for a typical grounding system and electric power distribution system under fault conditions. The electric shock for a typical grounding system, i.g. TN system or TT system, under phase-to-earth or phase-to-neutral short-circuit faults is studied. It is found that the complicated grounding grid may have a low step voltage than a single electrode. The touch voltage under phase-to-earth or phase-to-neutral fault conditions is analyzed. The TT system generally has a higher touch voltage magnitude than the TN-C system.

“…When the PEEC method is adopted to analyze lightning transients in wire/plate structures in the air and lossy-ground space, it is necessary to evaluate the Green's functions for layered media for both vector and scalar potentials for source and field points in any of these two layers. This approach has been applied to address both transient current and voltage in a variety of structures with arbitrarily oriented lines and plates [143], [144], [145], [146], [147], [148], [149], [150], [151], [152], [153].…”

This year marks about half a century since the birth of the technique known as the partial element equivalent circuit modeling approach. This method was initially conceived to model the behavior of interconnect-type problems for computer-integrated circuits. An important industrial requirement was the computation of general inductances in integrated circuits and packages. Since then, the advances in methods and applications made it suitable for modeling a large class of electromagnetic problems, especially in the electromagnetic compatibility (EMC)/signal and power integrity (SI/PI) areas. The purpose of this article is to present an overview of all aspects of the method, from its beginning to the present day, with special attention to the developments that have made it suitable for EMC/SI/PI problems.

This article proposes asymptotic methods for calculating Sommerfeld integrals, which enable us to calculate the integral using the expansion of a function into an infinite power series at the saddle point, where the role of a rapidly oscillating function under the integral can be fulfilled either by an exponential or by its product by the Hankel function. The proposed types of Sommerfeld integrals are generalized on the basis of integral representations of the Hertz radiator fields in the form of the inverse Hankel transform with the subsequent replacement of the Bessel function by the Hankel function. It is shown that the numerical values of the saddle point are complex. During integration, reference or so-called standard integrals, which contain the main features of the integrand function, were used. As a demonstration of the accuracy of the technique, a previously known asymptotic formula for the Hankel functions was obtained in the form of an infinite series. The proposed method for calculating Sommerfeld integrals can be useful in solving the half-space Sommerfeld problem. The authors present an example in the form of an infinite series for the magnetic field of reflected waves, obtained directly through the Sommerfeld integral (SI).
