<![CDATA[A Single phase medium voltage power cable (XLPE) buried in soil and it can be used to investigate electric field, potential distribution and increased temperature of the cable insulation with rising load currents, are known to accelerate the formation of water and electric trees in cables which ultimately lead to cables failure. To determine the thermal and electrical behavior of a given wet cable installation. The work presented in this paper involves the use of COMSOL multiphysics Finite Element software to develop an integrated electrical, thermal model with 3 micro meter water bubble radius. The presence of water tree results in the reduction of their dielectric strength. Here the Finite Element simulation technique is used to 11 kV and 20 kV power cables. A model that illustrates the water-dielectric interface within the cable insulation system is proposed.]]>
