Dielectric analysis of vegetable and mineral oils

Popis výsledku v původním jazyce

This paper deals with analysis and comparison of the specific dielectric properties and chemical structure of sunflower, rapeseed and commonly used transformer mineral oil. The measured sunflower and rapeseed oils are natural ester molecules with a triglyceride structure and have mainly excellent fire resistance and biodegradability. The measured common mineral oil is produced from mixture of hydrocarbons from crude oil and belongs to the group of naphthenic oils consisting mainly of cycloalkanes and isrelatively flammable and dangerous for living environment. The measurement was performed by means of the dielectric spectroscopy method. The real and imaginary parts of complex permittivity of measured samples were analyzed in a frequency range from 50mHz to 100 kHz and in temperature range from -50 °C to +90 °C. The measured spectrums displayed relaxation processes (alfa and beta) as well as the conductive component (sigma). The results showed that the measured dielectric properties o
