Reliability in the supply of electricity depends on isolation from the electrical power system. Insulators are components that have the function of insulating and supporting the electrical grid. The design of electrical distribution network insulators can have a great influence on the distribution of the electric field over its surface. When there is a great intensity of electric field applied specifically in a location, there may be a greater chance of the development of a fault. An optimized insulator profile design can ensure that the network has better performance. In this paper, particle swarm optimization is applied to optimize the profile of an insulator of the conventional electric power grid, based on the electrical potential data obtained using the finite element method, defined in this paper as optimized finite element method. The component parameters are optimized to obtain a parametric model. The parametric model is evaluated and compared with the usually employed profiles to define an optimized design. The results show that the proposed method is a promising alternative for the design of electrical energy distribution insulators.

电力供应的可靠性取决于与电力系统的隔离。绝缘体是具有绝缘和支撑电网功能的部件。配电网络绝缘子的设计对其表面的电场分布有很大影响。当在某个位置专门施加很大强度的电场时，发生故障的可能性就更大。优化的绝缘子轮廓设计可以确保网络具有更好的性能。在本文中，基于使用有限元方法获得的电势数据，应用粒子群优化来优化常规电网绝缘体的轮廓，本文将其定义为优化有限元方法。优化组件参数以获得参数模型。参数模型被评估并与通常采用的配置文件进行比较以定义优化设计。结果表明，所提出的方法是设计电能分配绝缘体的一种有前途的替代方法。
