Special Issue Information

Dear Colleagues,

Symmetry/asymmetry is a universal issue for engineering. Regarding electrical and electronic engineering, there are also symmetry/asymmetry-related problems. For instance, charging and de-charging is a typical symmetrical process. To further dig into symmetry/asymmetry research in electrical and electronic engineering, the Special Issue “Electrical and Electronic Engineering with Symmetry/Asymmetry” has been organized. This Special Issue will cover various research in electrical and electronic engineering related of symmetry/asymmetry. Researchers are invited to submit original research papers and review articles related to any electrical engineering and electronic engineering discipline in which theoretical or practical issues of symmetry are considered. Topics of interest for this Special Issue include (but are not limited to) the following:

  • Symmetry/asymmetry in topology/geometry design of electrical and electronic engineering;
  • Symmetry/asymmetry in modelling and computing of electrical and electronic engineering;
  • Symmetry/asymmetry in experiment and test of electrical and electronic engineering;
  • Symmetry/asymmetry in physical/chemical process of electrical and electronic engineering;
  • Symmetry/asymmetry in system analysis of electrical and electronic engineering;
  • Symmetry/asymmetry in component analysis of electrical and electronic engineering;
  • Symmetry/asymmetry in material research of electrical and electronic engineering.

Temperature is an important factor for the service life of cable insulation. To ensure safety, the operating temperature of cables must be monitored. Since optical fiber temperature measurement technology is difficult to be used widely in medium voltage (MV) cables due to cost, this paper proposes a temperature evaluation method based on wave velocity. Firstly, the dielectric constant of cross-linked polyethylene (XLPE) cable insulation under different temperature is obtained through experiment. Based on the result, the relationship curve between wave velocity and temperature is established. The asymmetry effect due to temperature gradient in the cable insulation is discussed via finite element simulation. The effectiveness of obtaining the average insulation temperature of the cable based on wave velocity is validated. In addition, the mechanism of the temperature influence on the cable insulation material’s dielectric constant is analyzed by molecular dynamics simulation, which further deepens understanding of the characteristics of cable insulation materials.
