Abstract

Dc space-charge measurements, performed by PEA, are used to estimate the electrical threshold in XLPE and modified XLPE-based materials. In addition to threshold, a quantity is proposed for the characterization of a material, in relation to its expected voltage endurance. This quantity is associated to the slope of the charge vs field plot coming from space-charge measurements. The different behavior as regards space-charge accumulation in the tested materials and its relevance to insulation endurance is discussed. The quantities presented in this paper are thought useful for electrical characterization of insulating materials candidate for DC high-field applications.
