Investigation of characteristics of cables in high frequency for power line communication using finite element Analysis

The increasing use of PLC modems in smart grids highlights their vulnerability to signal attenuation influenced by cable shape and material properties. While cable design significantly impacts signal transmission, the complex relationships between cable characteristics and performance at varying frequencies are less understood. This study uses finite element analysis to investigate signal attenuation and transmission anomalies in low-voltage (LV) cables, especially under high-frequency conditions in smart grid communications. Using COMSOL Multiphysics, detailed simulations of electrical and magnetic properties for various LV cable designs aim to optimize cable characteristics, reduce attenuation, and enhance signal integrity. The research compares Coaxial and NAYY cables, offering recommendations to improve smart grid communications infrastructure.
