Electric Field and Thermal Properties of Dry Cable Using FEM


The Cross linked polyethylene (XLPE) insulated power cables are used for transmission and distribution of electrical power for higher voltage level. In this paper a Single phase medium voltage power cable buried in soil and it can be used to investigate electric field distribution, potential distribution and temperature distribution in a cable is analyzed and presented. In the present study the voltage distribution of an underground cable of 11kV is analyzed using FEM and its electric field and temperature distribution is calculated by analytical method. Result obtained indicates that the radial temperature distribution of the Single Phase cable do not flattened distribution. Further their performance parameter is verified using Comsol Multi Physics software. The results obtained using Comsol Multi Physics software is also compared with the analytical results which is obtained through literature review.
