This study analyzes the sensitivity of polymer long-rod insulator shed geometry to the maximum electric field concentration (Emax) using the Finite Difference Method (FDM). Polymer insulators are susceptible to premature aging and dielectric failure, often triggered by high Emax around shed junctions or surfaces. 2-dimensional axisymmetric FDM simulations were applied to model the insulator, varying shed geometry parameters such as shed angle, height, and spacing. The results indicate that shed spacing is the most sensitive parameter, where a reduction in spacing significantly increases Emax by up to several tens of percent. In contrast, changes in shed angle and height have a smaller impact. This analysis provides critical insight into the optimal design of polymer insulators to minimize electrical stress and prolong service life in high-voltage networks.
