%X Sa£żetak Electricity powers the world and is an indispensable product for humanity, almost like water and food. This energy category needs two types of materials which make it feasible - electrical conductors and electrical insulators. In practice, no one can afford to use ideal conductors and insulations matrixes. Accordingly, the industry has to compromise with the best available materials at acceptable prices. Power transformers, like any other electrical device, have to contain these two types of materials. The most advantageous insulation media for most power transformers today is liquid insulation combined with solid insulation for both mechanical and electrical strength. It is well known that increases in temperature of conductive and insulating materials decrease their capabilities to conduct and to isolate the electricity, respectively. Temperature positive feedback deteriorates the properties of both media, conductors and insulators, exponentially
