Modular digital twin modelling method for 10 kV cable lines based on real‐time temperature field inversion

High Voltage, Volume 10, Issue 1, Page 56-68, February 2025.
Abstract State perception of long‐span 10 kV cable lines is one of the critical issues in building intelligent distribution networks. Digital twin (DT), which can map the physical status of equipment in real‐time, has received extensive attention. However, traditional modelling methods cannot meet the requirement of long‐span complex DT's real‐time ...

Influence of different anodised nanoporous structures on the anti‐icing and electrical properties of transmission Al lines

High Voltage, Volume 10, Issue 1, Page 167-177, February 2025.
Abstract Ice accumulation of overhead transmission lines can lead to serious damage to power systems. Superhydrophobic nanostructured Al conductors are proposed to replace the de‐icing or ice‐melting equipment for economic advantages, good anti‐icing properties and robust electrical performance.
