Experimental Verification and Finite Element Analysis of Short-Circuit Electromagnetic Force for Dry-Type Transformer

摘要

This paper presents short-circuit electromagnetic forces for a dry-type transformer. The electromagnetic forces in windings are calculated using finite element analysis (FEA). In order to predict the stresses and the displacements of the windings, the structural analysis is executed by using the electromagnetic analysis results. The results are compared to those of measured ones and showed good agreement with experimental results.
