Dynamic analysis of flashover in high voltage DC polluted insulator

, 1992
The actual voltage growing in electrical power systems make the insulation studies, very important. In this, one of the principal problems is the development of discharges in surface polluted high tension insulators.

Displacement Current and Surface Flashover [PDF]

, 2007
High-voltage vacuum insulator failure is generally due to surface flashover rather than insulator bulk breakdown. Vacuum surface flashover is widely believed to be initiated by a secondary electron emission avalanche along the vacuum-insulator interface.

Effects of metal particle material on surface flashover performance of alumina-filled epoxy resin spacers in SF6/N2 mixtures under DC voltage

AIP Advances, 2019
When metal particle is attached on spacer surface, it will distort surface electric field and may reduce surface insulation level. Therefore, it is important to research the relationship between metal particle attachment and surface flashover property ...

DC Flashover Dynamic Model of Post Insulator under Non-Uniform Pollution between Windward and Leeward Sides

Energies, 2019
Experience shows that under unidirectional wind or certain terrain, the surface of post insulators is non-uniformly polluted between windward and leeward sides, which affects the flashover characteristics.
