Computation of Electric Field and Thermal Properties of 3-Phase Cable
Abstract: In this paper the
electric field distribution, potential distribution and temperature
distribution in a 3-phase underground cable in common ground enclosure is
analyzed and presented. Unlike 3-Phase screened cable the stress distribution
in a belted cable is not radial. A 3-phase high voltage power cable buried in
soil can be used to investigate its electrical and thermal properties. In the
present study the voltage distribution of an underground cable of 132 kV is
analyzed using FEM and its ampacity and temperature distribution is calculated
by analytical method. Further their performance parameter is verified using
Comsol Multiphysics software. The results obtained using comsol software is
also compared with the results of CSM model which is obtained through
literature review.
