Computation of Electric Field and Thermal Properties of 3-Phase Cable

Abstract

Pada makalah ini, distribusi medan listrik, tegangan dan suhu dalam kabel bawah tanah 3 fasa dalam penutup pentanahan dianalisis dan dibentangkan. Tidak seperti kabel skrin 3 fasa, distribusi regangan dalam kabel yang berikat tidaklah radial. Sebuah kabel daya tegangan tinggi 3 fasa yang dikubur dalam tanah dapat digunakan untuk menyelidiki properti listrik dan termalnya. Pada studi ini, distribusi tegangan kabel bawah tanah 132 kV dianalisis menggunakan FEM sedangkan distribusi kapasitas arus dan suhunya dikalkulasi menggunakan metoda analitik. Selanjutnya parameter kinerja diverifikasi menggunakan perangkat lunak Comsol Multiphysics. Hasil yang diperoleh dibandingkan dengan model CSM yang diperoleh melalui kajian literatur.

Finite Element Analysis of Maximum Electric Field for Air Breakdown under Various Electrode Configurations

“…In order to determine the maximum electric field, a finite element method (FEM) is used for the computer simulation. FEM is a numerical method that is extensively used to obtain solutions for various engineering and science problems, including those are associated with electric field behaviour [10][11]. Thus, a simulation model of the selected electrode configurations with various gap lengths is developed in the computer software to analyze their electrical field behavior inside a test rig.…”
