An artificial intelligence system for a complex electromagnetic field problem. I. Finite element calculations and fuzzy logic development

Artificial intelligence (AI) has been used to determine the electromagnetic field in the complex problem of a faulty overhead transmission line above earth and a buried pipeline. A suitable AI system for scaling finite element electromagnetic field calculations has been developed. This system was trained by using finite element calculations for configurations, i.e., cases having different distances between the overhead transmission line and the buried pipeline as well as different earth resistivities. The AI system may be used to calculate the electromagnetic field in new cases differing significantly from the cases used for training.
