Effect of Temperature on Creeping Flashover Voltage of Nanofilled Oil-Pressboard Insulation
IEEE Access, 2020 Creeping flashover (surface discharge) at oil-pressboard interface is considered a serious failure of the insulation system in power transformers. In this paper, creeping flashover voltage at oil-pressboard interface using the concept of nanofluids is ...

Flashover and Transformer Voltage
IEEJ Transactions on Industry Applications, 2010 This thesis stated many examples about transformer voltage on the direct current motor and generator that those were measured. They suggest that a flashover occurrence often has an indirect influence.

Unraveling the “U-Shaped” Dependence of Surface Flashover Performance on the Surface Trap Level
IEEE Access, 2019 The effects of surface traps on surface flashover remain controversial. To clarify the relation between surface flashover and surface trap level, in this work, the surface trap level of epoxy composites was modified by nanoparticles incorporation ...

Flashover characteristics of a droplet impacting the silicone rubber surface
AIP Advances, 2023 The surface discharge of silicone rubber (SIR) is one of the main reasons to accelerate the aging of its surface material in power systems. It is known that static water droplets on the SIR surface can make the flashover voltage substantially fall, while
