Ternary insulation systems are used for several decades in high voltage engineering. The main problem is their inhomogeneous structure which may cause defects during operation and this can limit the life of the entire device. Currently, there are efforts to develop material that is macroscopically homogeneous. Homogenization of material results in a reduction of differences of local electric field...
This paper deals with experimental results of the combined electrical and thermal aging of two epoxy resins with nanosilica subjected to AC voltages. Overall 20 samples were prepared. Ten samples contain laboratory epoxy resin DGEBA, hardener Laromin C260, and nanosilica. Other 10 samples contain industrially used epoxy resin Epoxylite also with nanosilica. These ensembles had been measured prior...
This paper deals with analyses of chemical structure and real and imaginary parts of complex permittivity of sunflower, rapeseed and commonly used mineral oil. The sunflower and rapeseed oils measured are natural ester molecules with a triacylglycerol structure and have mainly very good fire resistance and biodegradability. The measured commonly used mineral oil is a mixture of hydrocarbons produced...
