Insulator strings with various materials and profiles are prevalent in overhead transmission lines, yet the distribution of electric fields and voltages along these strings is uneven, leading to issues such as corona, deterioration of insulator surfaces, and flashovers. This study aims to comprehensively analyze the effect of different insulator types on the electric field and voltage distribution across 230-kV insulator strings. Using three-dimensional finite element method (FEM) based simulations, several configurations of porcelain and glass insulators were modeled to quantify and compare electric fields and voltage distributions. The research incorporated both tower and conductor influences into all simulations, with a specific focus on how the presence of a corona ring impacts these distributions. Results indicate a significant dependence of voltage distribution on the material and profile of the insulators, underscoring the importance of material selection in optimizing insulator performance and reliability in electrical systems.
