Investigations to determine the relevant electric and dielectric properties of certain insulating fluids which appeared most suitable from the viewpoint of environmental compatibility and inflammability are discussed. Two of these are silicone fluids based on linear polydimethyl siloxane (kinematic viscosity at 25 degrees C is 50 mm/sup 2//s) and an ester fluid based on penthaerythrithol tetraester. After a short description of the insulating fluids, the influence of aging on the breakdown and dissipation factor is determined. Furthermore, a comparison of the breakdown and aging behavior of fluid-paper composite dielectrics is made. The influence of partial discharge prestressing on the breakdown of the fluid-paper composite dielectric is shown.>
