Solid Dielectrics

Solid dielectrics

A wide range of different materials are used as solid dielectrics in high voltage plant. Although much use has been made of paper and oil as insulation, the tendency is now to move towards synthetic polymers. As a result, understanding the effects of temperature, mechanical loadings and electrical stresses on polymeric insulation is technologically important and presents numerous scientific challenges.

Ongoing projects include the electrical, chemical and structural characterization of electrical trees, electroluminescence studies, structure/property relationships in polymers and nanocomposites.
