Special Issue Information

Dear Colleagues,

Let me welcome you to this Special Issue of MDPI’s Energies entitled “Advances in Partial Discharge Measurements”. This Special Issue focuses on new developments in partial discharge measurements in high-voltage equipment. Partial discharge measurements are always in constant development. In recent years, new trends in partial discharge measurements have appeared, partially due to the increase of online monitoring systems and new challenges derived from HVDC technologies and renewable energy integration.

In this Special Issue we would like to cover the latest developments related to partial discharge measurements. This includes, but is not limited to:

  • The application of artificial intelligence or machine learning techniques to the identification or location of partial discharges in cables, GIS, or transformers.
  • The integration of advanced signal processing tools for noise reduction or feature extraction in online monitoring systems.
  • New developments for the monitoring and diagnostics of long cables and offshore submarine cables and systems.
  • New tools for HVDC defect recognition and pattern recognition.
  • Development of new electromagnetic, optical, or acoustic sensors for online measurements.
  • Developments in SF6 alternative gases partial discharge monitoring.
  • New calibration techniques for online systems.
  • Behavior of partial discharges at high frequencies.
  • Effects of transients in partial discharge measurements.

Certainly, the future is very challenging. We would be pleased to have your contribution to this Special Issue on Advances in Partial Discharge Measurements.

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.

Without the Fluorinert solution and proper pad design, the high–voltage (HV) transistor used during the DC breakdown voltage (Vbk) measurement might be damaged by the partial discharge (PD) in the air if its Vbk is close to one thousand volts or more. From the waveform measurement, the PD in the air occurred at 650 V HV GaN HEMTs during the Vbk measurement, it is ignited by the unipolar arc, and it is not ignited by the avalanche breakdown. This is based on the fact that the current falls below zero ampere to become a negative current, and the voltage rises so that it is higher than the setting voltage of the DC meter at the onset of the PD, thus corresponding with the electrons, leaving the plasma to cathode, and enabling a build–in potential to exist in the plasma. Then, the PD ignites because the current starts to rise in order to allow for a positive spike current; the voltage level subsequently falls and a lower voltage reading is obtained. Full article
