Reliability and durability of polymer insulators of the contact network
Вестник Научно-исследовательского института железнодорожного транспорта, 2018 On the network of electrified railroads and power lines of advanced countries there is an intensive work undergoing on the conversion of traditional insulating structures made of porcelain and glass to new ones - polymeric. In order to minimize mechanical

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
