Abstract
High voltage insulators are critical components in power transmission systems. They provide both mechanical support and electrical insulation for energized conductors. This study focuses on evaluating the electrical behavior of a 1512L glass insulator affected by damage or fracture. The analysis is performed using a three-dimensional simulation approach with COMSOL Multiphysics. The model considers different damage locations (top, middle, bottom) along the insulator body to study their influence on the electric potential and field distribution. The work contributes to understanding how damage location may influence the electrical stress on the insulator under service conditions.
