Dielectric Changes of PET and Glass-fiber Based Epoxy Composites During Thermal Aging

Popis výsledku v původním jazyce

The paper deals with the problem of thermal aging of PET and Glass-fibre based composites. These electroinsulating materials are used in high voltage engineering as parts of insulation systems of large rotating machines like turbo or hydro generators. These materials were subjected to accelerated thermal aging to provide more information about the aging effects and allow us to estimate the lifetime of the materials at operating temperatures. The laboratory method used to compare the dielectric properties (relative permittivity, loss factor, parallel capacitance, parallel resistance and impedance) during the accelerated thermal aging was the dielectric spectroscopy. Thermal aging of the samples was performed in the laboratory thermal oven and the changes of their physical and chemical properties were measured and evaluated at given exposure times. Different temperatures (170 ? 194 °C) were chosen for the accelerating of the aging process. The aging time was determined for each temperatu
