High Frequency Analysis of Single Overhead Line Terminated to Grounded Arrester Using Fuzzy Inference Models

Abstract— in this paper, intelligent models based on fuzzy inference are proposed to analyze single overhead line terminated to arrester. this paper consists of two parts. the first one is modeling overhead line; and the second one is related to modeling grounding system. in each part, the behavior of the problem is first represented as simple and unchanged membership functions. after then, effects of parameters of the problem such as height of overhead line, and lightning-strike pointare extracted as simple curves. as a result, theseachieved models in despite of transmission line model (tlm) is applicable for high frequencies created by lightning strikes.
