Abstract
It is generally accepted that mechanical strains and stresses have a significant influence on the electrical performance of polymeric materials. The aim of this investigation is to quantify the residual stresses created around embedded needles in XLPE pin-plane specimens for quenched and slowly cooled samples. The paper also examines the effect of these highly divergent mechanical stress fields on the time-to-inception of electrical trees
