Space charge accumulation in polymeric insulation could distort the field distribution and affect the insulation properties. In this project, charge injection and transportation inside the polymeric insulation will be investigated by numerical modelling and experimental measurements. The thermal impacts on space charge behaviours will be especially considered. A modified numerical model is expected to be built which can be used to study the charge dynamics and to anticipate the electric field variation across the insulation. In order to obtain the space charge dynamics under practical application situations, a cable PEA system is built which considering the thermal effects caused by the current flowing in the core of cable.
