Ageing and reliability of electrical insulation: the risk of hybrid AC/DC grids
High Voltage, 2020 With an impetuous growth of DC links and future grids that will be often hybrid, providing AC and DC supply to nearby or the same customer, an important element is often neglected, that is, electrical insulation.

In‐situ observation of electrical tree evolution in epoxy dielectrics with internal cracks
High Voltage, 2021 Gas‐filled internal crack might appear in thermoset materials like epoxy resin during the equipment manufacturing, which would become a vulnerable local region to initiate the electrical tree, thus prone to cause insulation failure. The withstand voltage

Durability of crosslinked polydimethylsyloxanes: the case of composite insulators
Science and Technology of Advanced Materials, 2008 Most applications of silicones are linked to their hydrophobic properties and (or) their high resistance to ageing (e.g. thermal ageing and photoageing). However, when placed in extreme environments, these materials can fail as in the case of epoxy/fiber
