This study uses finite element simulation to present a comprehensive dielectric field analysis of a medium-voltage (MV) fuse holder. The primary objective is to identify regions of elevated electric field intensity that may compromise insulation integrity and to propose design modifications that enhance dielectric reliability. Initial simulations under rated lightning impulse conditions revealed critical stress concentrations, particularly at the front and middle sections of the fuse holder, posing a significant risk of flashover. To address these issues, several design enhancements have been implemented, including geometric optimization and the integration of stress regulators, field grading elements, and aluminum fence structures, all aimed at redistributing the electric field intensity. Post-modification simulations demonstrated a remarkable reduction in peak electric field values, shifting the maximum stress region to a less critical zone. These improvements are validated through physical testing, which confirms the effectiveness of the new design in mitigating dielectric stress and enhancing overall insulation performance.
