Abstract
From a theoretical viewpoint it is shown that low-permittivity liquids are preferable as insulation impregnants when low dissipation factors are requested. It was confirmed by tests on capacitors that they lead to better thermal stability. Tests performed on capacitor micromodels show the influence of viscosity and aromaticity, and to a lesser extent chemical structure, on the liquid performances under very high stress. Tests performed on all types of capacitors were in agreement with these results
