Analysis of Electric Field Values in 24 kV High Voltage Power Cable with Program for Finding Partial Discharge Values

Abstract

This research studies and demonstrates the comparison of partial discharges (PD) in the XLPE underground high voltage cable between cables that are used with the new cables and used as results of the electric field analysis in the underground high voltage cables. The simulation of the underground cable has been applied using the compact software of Comsol Multiphysics.5.3 The underground high voltage cables for 24 kV rated voltage is prepared for analysis between simulation and PD measurement test in both the used cable and the new cable. The study is found that some discharges in the XLPE underground high voltage cables occur in the new cable which can be analyzed electric fields within the insulation cable by using Comsol Multiphysics 5.3 program. It is assumed that some discharging might be the internal charging type in somewhere of the dielectric cable. This point might lead to a significantly higher discharge rate than the XLPE cable of the new cable. Therefore, the used underground cable should be tested for information leading to the recovery of the power system.
