Abstract :
High voltage dielectric frequency response measurements have been performed on laboratory aged polyethylene samples with special attention for studying non-linear effects during water tree ageing. A measurement set-up for making high voltage and high sensitive measurements on disc shaped samples in the range of 10 pF is presented. Prior to ageing, the samples were vacuum treated and then equipped with evaporated aluminium ground electrode
