DC Electric Field Analysis of Nomex, Kraft Paper, and PPLP Insulation Arrangement in Liquid Nitrogen by Using COMSOL Multiphysics

For the supreme performance of the superconducting cable, insulation decides the ability of the cable to withstand the operating voltage or not. So insulation is the main focused area in the superconducting cable to decide its selectivity, preference, and performance over the other cable. The major aim of this simulation-based analysis is to analyze dielectric characteristics of Nomex, Kraft Paper, and PPLP Insulation arrangement in liquid Nitrogen. Dielectric characteristics this resulting combination is analyzed by using COMSOL Multiphysics software as a simulator. For determining the dielectric characteristics, a voltage of the style Ramp voltage and a step voltage have been provided and the behavior of Nomex insulation, Kraft Paper, and PPLP insulation is observed under these voltages.
