New Approach in Insulation System of Power Transformers - Insulating Oils with Less Impact on the Environment

Popis výsledku v původním jazyce

Paper deals with comparison of selected properties of several vegetable oil representatives (commercially available ENVIROTEMP? FR3TM vegetablebased transformer oil, sunflower oil, rape oil and refined sunflower and rape oil) along their accelerated thermal ageing at the temperature of 90 °C. These properties are compared to two widely used and commercially available mineral transformer oils (Technol Y 3000 and Shell Diala DX). Combined insulating system (oil-paper system) was created with the usage ofmentioned oils for measurement purposes. Dissipation factor, capacity and volume resistance are the characteristics measured along the thermal ageing of the oilpaper systems. Infrared spectroscopy was used as the additional method. After 1000 hours of ageing, the dissipation factor of all systems based on vegetable oils did not exceed the value of 0,015. The volume resistance of systems containing mineral oils was approx. twice as high as volume resistance of those with vegetable oils. C
