Parameters that influence the partial discharges occurrence in cavity defect within electrical cable insulation

Diagnostyka, 2023
The electrical cable reliability is largely linked to the state of its insulation, which can be threatened by the partial discharges (PDs) activity. This phenomenon is localized in defects created within insulation during the manufacture process and the ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
