Local Vector Magnetic Characteristic Analysis of a Three-Phase Three-Leg Transformer Model Core

Abstract:

This paper presents results of magnetic characteristic analysis of a three-phase three-leg transformer model core. In the analysis, the finite element method considering vector magnetic properties expressed by the integration-type E&S modelling is used. In this research, in order to reduce total iron loss, local vector magnetic properties for some different T-jointed models are compared in detail. Distributions of maximum flux density, maximum field strength, axis ratio and iron loss depending on the T-jointed position are clarified.
