This paper presents a literature review on the subject of Condition-Based Maintenance of surge arresters. Both a bibliometric analysis and traditional comprehensive research are presented. The bibliometric analysis is useful for obtaining insights about the literature. It quantitatively highlights relationships between journals, authors and keywords (related to the monitoring methods) and reveals future trends for research based on the timeline of the keywords. The traditional comprehensive literature review is also presented. It summarizes the methods, their advantages and disadvantages and also points to some known measurement issues of the methods. Both online (leakage current, harmonic components, temperature, partial discharges, power loss and the counting of discharges) and offline (reference voltage, residual voltage, insulation resistance, polarization/depolarization, return voltage, microscopy, spectrometry, X-ray, RUS and the recent application of FRA) methods have been qualitatively analyzed.

“…The second major topic treats general methodological advances in numerical methods 5,6 . The third major topic is the application of modeling to the study, design, and optimization of a wide range of technological devices, spanning low‐ to high‐frequency electromagnetic regimes: from magnetostatics 7,8 to electro‐ 9,10 and magneto‐quasistatics, 11,12 to full‐wave 13,14 . This underlines the spirit of the conference, which encompasses both theory and practical applications.…”

On behalf of the Editorial Board, we are pleased to present a selection of papers related to the 12th International Symposium on Electric and Magnetic Fields (EMF 2021), held online on July 6-8, 2021.The EMF symposium series, whose first edition was held in Liège, Belgium, in 1992, aims at building a bridge between recent research advances in mathematical and numerical modeling of electromagnetic fields and the growing number of industrial problems requiring such techniques. In the aftermath of the global COVID-19 pandemic, the 12th edition was organized online, and attracted 84 participants from 17 countries.Among the 62 presentations in the symposium program, 24 manuscripts were submitted for peer review. Fourteen papers were selected for publication in this special issue of the International Journal of Numerical Modelling: Electronic Networks, Devices and Fields. The high scientific and technical quality of the symposium is well reflected in the quality of the manuscripts contained in this special issue.Three broad topics were covered during the 12th edition of the symposium. The first major topic considers the mathematical modeling of electromagnetic problems in view of their eventual numerical solution on computers, with contributions on quasistatic time-domain formulations 1-3 and high-frequency formulations. 4 The second major topic treats general methodological advances in numerical methods. 5,6 The third major topic is the application of modeling to the study, design, and optimization of a wide range of technological devices, spanning low-to high-frequency electromagnetic regimes: from magnetostatics 7,8 to electro-9,10 and magneto-quasistatics, 11,12 to full-wave. 13,14 This underlines the spirit of the conference, which encompasses both theory and practical applications.We express our gratitude to all the members of the EMF scientific committee-P.

Adjoint variable method for transient nonlinear electroquasistatic problems

et al. 2023

Many optimization problems in electrical engineering consider a large number of design parameters. A sensitivity analysis identifies the design parameters with the strongest influence on the problem of interest. This paper introduces the adjoint variable method as an efficient approach to study sensitivities of nonlinear electroquasistatic problems in time domain. In contrast to the more common direct sensitivity method, the adjoint variable method has a computational cost nearly independent of the number of parameters. The method is applied to study the sensitivity of the field grading material parameters on the performance of a 320 kV cable joint specimen, which is modeled as a finite element nonlinear transient electroquasistatic problem. Special attention is paid to the treatment of quantities of interest, which are evaluated at specific points in time or space. It is shown that the method is a valuable tool to study this strongly nonlinear and highly transient technical example.
