Original Abstract

The article deals with dielectric studies of aging phenomena in commercially used high-temperature mica insulations. Insulation samples were aged at the temperature of 320°C for 500 hours and then were stressed by electric fields. The objective of the analysis was to examine whether the electrical breakdown, which is a pronounced localized event, is preceded by changes of bulk material properties – frequency and temperature dependence of the complex permittivity. The measurements carried out so far show the presence of at least one relaxation process and one conduction process. Both mechanisms depend strongly on temperature but they seem to be very little affected by electrical stress.

Key words in English
