dc.description.abstractDielectric frequency spectroscopy of polymer materials were done in laboratory. The aim was to investigate the (i) differences in dielectric losses of the industrially manufactured silicone rubbers against laboratory manufactured silicone rubbers, (ii) differences in dielectric losses for the epoxy resin samples manufactured in laboratory, but with different curing time, and (iii) differences of dielectric losses between each single polymer to the losses of the series joined specimens of the two polymers. The measurements were done using the Insulation Diagnostics System in laboratory at ambient room conditions. It has been found out that for different frequency ranges, silicone rubber manufactured industrially differ with the laboratory manufactured specimens. The series joined specimens show higher influence of the silicone rubber in both curve shape, and values of losses at frequencies lower than 1 Hz. At frequencies lower than 1 Hz the joined specimen losses are higher than losses for epoxy resin and lower than those for silicone rubber. At frequencies higher than 1 Hz the losses of the joined samples are close but slightly lower to those of epoxy resin and higher than those of silicone rubbers. Lastly, the curves of the joined specimens have shapes which strongly resembles those of the silicone rubbers.en_US
