“…The authors quote our paper [4], seemingly describing it as a numerical method to analyze the field distribution by the finite difference method. In doing so, they do not recognize another significant topic, deeply analyzed in that work, which (once again, to us) appears at least as important as the analytical electro-quasistatic (EQ) field model.…”

267 DISCUSSION 1-Dimensional Model for Nonlinear StressControl in Cable Terminations N a recent paper [l], a problem of considerable engineering interest I concerning the evaluation of the voltage profile in a cable termination equipped with stress grading materials has been discussed. In the paper, the potential distribution inside the termination is evaluated both for linear and nonlinear materials by adopting the well-known RC transmission line model.Although both the problem and the model adopted are not new (see for example the bibliography in [l]), the paper introduces and discusses two novel aspects, of theoretical and practical interest for the electrical engineer involved in the design of cable terminations, which are worth considering.The first one is the use of a characteristic parameter, called 'penetration length, in order to describe quantitatively the ability of the stress grading material to reduce the field strength at the shield cut. The second novelty is the supposed possibility to analyze the general nonlinear resistive-capacitive field control problem: both a nonlinear resistivity and permittivity (of the power-law type) are allowed in the mathematical model describing the voltage distribution along the termination. It is interesting to note that some of the results presented in [l] are derived by using those obtained by the same authors in a previous work concerning the magnetic field dynamics in high temperature superconductors.The efforts made by the authors of [l] to provide simple relations for the evaluation of the voltage distribution and the effectiveness of the field control are noteworthy. However, the results they obtain are of limited interest, due to a rather relevant conceptual oversight in the general theoretical model and some rather meaningless approximations in the analysis of particular cases.

“…Cable terminations (Lupo et al, 1996;Raičević & Aleksić, 2010;Raičević, 1999) and cable joints (Raičević, 2007a) belong to the most sensitive parts of electrical power lines. The cable terminations are supposed to have small dimensions and very good service characteristics.…”

Hybrid Boundary Element Method for Multi-Layer Electrostatic and Magnetostatic Problems

A hybrid numerical method is proposed involving a successful combination of the equivalent electrodes and boundary element method. Electric field and electric potential distribution are determined by using both equivalent electrodes and equivalent charges. Green's function for potential of the charge per unit length, placed in free space, on the boundary of two dielectrics, is used. Magnetic-field distribution is determined by applying equivalent currents through magnetic vector potential and substitution of Ampere's microscopic currents with total currents. The accuracy of the developed method is highlighted with some simple numerical examples.
