Estimation of the Critical Flashover Voltage for Different Polluted Insulators by Particle Swarm Optimization

This article presents an optimization method to determine the arc constants used in the mathematical model which concerns the critical flashover voltage of a polluted insulator. These constants must be standard for many insulators, hence the establishment of a model that very accurately simulates the experimental results. The optimization method based on Particle Swarm Optimization (PSO) that resolves a problem by iteratively trying to improve a candidate solution with regard to a given measure of validity. It can be seen that the calculated results by application of PSO has allowed to define the constants of the arc where the establishment of a model that simulates the experimental and analytical results of other researchers.
