Case Study: Optimizing Grading Ring Design for High Voltage Polymeric Insulators in Power Transmission Systems for Enhanced Electric Field and Voltage Distribution by Using a Finite Element Method

This research paper aims to investigate the optimal design of grading rings for high-voltage polymeric insulators in an actual power transmission system, with a focus on improving electrical representation insulator strings. One such subsidiary accessory commonly used porcelain and polymer strings is ring, which employed improve electric field voltage distribution surrounding string. The efficiency can be enhanced by rings, as they facilitate more linear potential division along parameters significantly influence their performance In this study, we examine insulators, since no uniform methodology has been developed optimization currently subject many studies. outdoor examined using finite element method (FEM) software COMSOL Multi-Physics program. A 2D model utilized simulate 220 kV insulator. effectiveness greatly depends dimensions locations rings. Therefore, impacts radius ring that its tube tube’s vertical position are thoroughly investigated, under dry humid conditions. To achieve objective, search algorithm adjust ring. approach study based determining maximum across surface, while ensuring it remains below corona initiation level.
