HV-insulation of simple forms

The operational reliability of high voltage power equipment depends mainly on the quality of electrical insulation. The main characteristics determining insulating structure (IS) quality are: -flashover voltage distribution (FOV); -volt-time curve (VTC); It is currently thought that POV follows the normal symmetrical law of distribution, while the VTC are inversely proportional to the degree function (socalled “hyperbolic type”). However, a series of IS discharge characteristics exist which differ significantly from the norm, both in flashover voltage quantity and in form. This paper discusses some results of IS investigations by the author in this area, based on research carried out in the 1980’s in Russia at the HV Center of Siberian Research Institute of Energetic (Novosibirsk) [l]. Paper hals only the most unquestionable and systematical part (basically experimental). The rest of results, into a good deal in higher extents interesting, also there are, but in connection with the limited sizes of one paper cannot be published right away as the logical streaking of heaved theme, viz: “To question about the mechanism of the formation of anomalous characteristics ...” and “The paths of streaking, and the prospects of application in Power Systems ...”
