“…6 The wire-to-shield voltage at the cable ends acquired by the proposed model is appeared in Fig.7 together with the outcomes determined by the FDTD [15], where the "FDTD" implies the finite difference time domain solution to the transmission-line equations of the cable, and by the compact circuit model proposed in [10]. They are in very good agreement with each other.…”

“…The major redesign method of the cable route is to identify ''interference field'' locations that are creating disturbances for LV and control cables or other sensitive transmission conductors [14][15][16]. Although shielding seems to be good enough from an engineering point of view, it should be recognized that high efficiency and economy in a system are incompatible.…”

This paper proposes a novel method for an optimal cabling route; a combinatorial design algorithm through heuristic mathematical formulations to choose the optimal path when two or more physical paths are available. The best path, from an EMC point of view, can be chosen based upon various criteria, such as monetary cost minimization, voltage drop and quality (EMC) parameters. This paper initially provides numerical 2D and 3D resolutions of the problems of radiation generated by current sources. The proposed approach is based on the finite element method, associated with absorbing boundary conditions. The presented model makes it possible to consider wave propagation and its effect on heterogeneous mediums in transient, which can be applied in EMC for simulation of radiation. Initially, the formulations for electromagnetic modeling of the proposed problem are specified in detail. The simulation results are used for the cabling routes, with respect to undesirable field distribution in the specified regions. Based upon the aforementioned criteria, using an Analytical Hierarchy Process, the intelligent choice of optimal cabling routes can be achieved. Hence, there is a need for the proposed method to be successfully implemented on two different types of power system; a current injection system, and high voltage substation.

“…In case of shielded cables such as coaxial, shielded foil twisted pairs (SFTP), twinax, the classical interrogative points regarding the connection of the cable shield has a certain answer: the cable shield must be connected at both ends to the chassis with a very low impedance connection especially at high frequency [2]. In fact, with the cable shield well connected to the chassis, in the high-frequency region where the skin effect become significant, the current I gnd produced by V i flows on the external part of the shield for both singleended (coaxial cable) and differential cables.…”

The paper deals with an investigation on the ground loop coupling by simulation tools based on the partial inductance concept. Several interconnect structures characterized by a signal line and its return conductor having different shape are considered. The prediction of the ground loop coupling is performed by an equivalent electrical circuit where the return conductor is modelled by its partial inductance Lgnd.. The calculation of L gnd is performed by SPICE simulation and by the Nodal Analysis of the equivalent circuit obtained decomposing the return ground into a finite number of parallel current filaments. The validity of this approach is shown by comparing the ground current distribution with that obtained by a full-wave solution with the Method of Moments
