Air voids in solid dielectrics affect the performance and lifespan of high voltage (HV) equipment. In this research, electric field distribution within a cross-linked polyethylene (XLPE) HV cable is analyzed using a finite element analysis (FEA) software, COMSOL Multiphysics. The study was performed in the presence of air cavity of different sizes within the insulation. The average as well as the maximum field strengths for both 2D and 3D of the healthy cable were observed to be equal under five (5) stressing voltage levels. The local field for 1 mm cavity radius in 3D was however lower than that of 2D model with an approximate percentage decrease of 9% for all the applied voltages. Further investigations on the 3D model show that average field rises with voltage and slightly decreases with increasing cavity size, while field enhancement is affected more by the cavity size than voltage stress.
