Analysis of the Mechanisms Determining the Thermal and Electrical Properties of Epoxy Nanocomposites for High Voltage Applications

The addition of microsized fillers to polymers, in order to tailor their properties, has been extensively used in many industrial applications since the 1960s. The same approach applies to the field of electrical insulation. Epoxy resin is a widely used polymer in the electrical power sector, but it is usually loaded with microsized fillers,...

Dielectric Strength and Thermal Conductivity of Mineral Oil based Nanofluids

In many applications of high voltage engineering, electrical and thermal stresses increase due to an ongoing decrease of product dimensions. In particular, the electrical industry is interested in applying nanofluids in transformers to be able to decrease transformer size and weight. The requirement for nanofluids is to enhance the electrical...
