Special Issue Information

Dear Colleagues,

The Guest Editor is inviting submissions to a Special Issue of Energies on “Electrical Engineering, High-Voltage, and Insulation Technologies: Second Edition”. The combination of high-voltage and insulation performances is important for the stability and duration of electric energy transmission and distribution. In recent years, there have been multiple emerging application techniques for power cable systems and overhead conductors.

This Special Issue will deal with the exploration of the latest electric power system applications and mechanisms. Topics of interest for publication include, but are not limited to, the following:

  • Long-term performance of high-voltage cable systems;
  • Electromagnetic interference originating from power cables in nuclear power plants;
  • Defect detection for power cable accessories;
  • Energy conversion in lightning fields;
  • Real-time capacity power system calculation and forecasting;
  • Insulation condition detection and tests.

Prof. Dr. Gang Liu
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

With advancements in cable manufacturing processes, the physical parameters of certain cable conductors fall outside of the scope specified by the IEC60287-1-1 standard, and the alternating current (AC) resistance calculated using the IEC standard may lead to reliability issues in the thermal evaluation of cable lines. Therefore, conducting an AC resistance test on cable conductors becomes critical for the thermal evaluation of cable lines. The source of error in the existing AC resistance test was analyzed first. It was found that the characteristics of the source used in the test lead to an error between the test value and the actual value of AC resistance. Moreover, an optimized AC resistance testing method based on active power was proposed to decrease the error. The accuracy of the method was also demonstrated. Finally, AC resistance tests were conducted on cable conductors with different cross-sectional areas, segmental methods, and oxidation methods by using the proposed method. The test results are also thoroughly discussed. Full article
