Abstract: This paper describes analysis of perspective, ecological and environmentally-friendly electrical insulating liquids for electrical engineering. In the experimental part, dielectric properties of the most common vegetable oils were analyzed and compared with frequently used noninhibited mineral oil (TrafoN): soybean oil, sunflower oil, rapeseed oil, peanut oil and two types of olive oils (extra virgen and pomace). Dielectric properties were measured using the high-resolution Novocontrol Alpha-A Frequency Analyzer in the frequency range 1 Hz – 1 MHz in the temperature interval 243 K – 363 K.
Keywords: activation energy; biodegrability; conductivity; dielectic constant; frequency dependence; insulating liquids; methyl oleate; mineral oil; natural oil; olive oil; peanut oil; rapeseed oil; soybean oil; sunflower oil; temperature dependence
