  • Abstract
    The combination of a dielectric solid (paper) and a dielectric liquid (mineral, vegetable, or silicone) is the most commonly used insulation system in power transformers because of the favorable dielectric properties of these insulations and the high heat capacity of the oil, which allows for cooling. It is known that temperature is the main parameter in determining the aging of these insulations and, therefore, the lifetime of a power transformer.
