High Voltage, EarlyView.ABSTRACT The thermal state of underground power cables can be monitored based on the temperature dependency of the dielectric permittivity of the insulation material. The resulting temperature‐dependent wave velocity is used as a thermometric property. To this end, the signal propagation time along a cable of an injected signal is determined.

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation
Advanced Functional Materials, Volume 36, Issue 30, 13 April 2026.A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

High Voltage, Volume 11, Issue 2, Page 410-420, April 2026.ABSTRACT Cross‐linked polyethylene (XLPE) cables play an important role in power systems to transport electrical energy, and moisture is one of the important predisposing factors for insulation failure in medium and high‐voltage cables. In this paper, a temperature‐moisture accelerated ageing experiment is designed, and a method for assessing the ...

High Voltage, Volume 11, Issue 2, Page 482-493, April 2026.ABSTRACT Low‐voltage cables insulated with silicone rubber were harvested from three locations in the primary containment vessel of a boiling water nuclear power plant (NPP). Subsequently, the cable, which was placed in an ambient environment with a relatively higher temperature and the highest rate, was cut into four shorter ones.
