Prediction of iron losses of wound core distribution transformers based on artificial neural networks

This paper presents an artificial neural network (ANN) approach to predicting and classifying distribution transformer specific iron losses, i.e., losses per weight unit. The ANN is trained to learn the relationship of several parameters affecting iron losses. For this reason, the ANN learning and testing sets are formed using actual industrial measurements, obtained from previous completed tra...

Modelling transformer core joints using Gaussian models for the magnetic flux density and permeability

Simple equivalent permeability and reluctance models are obtained for the transformer core joints from the analysis of the magnetic flux. It is shown that the flux variations in the joint zone can be fitted with simple Gaussian expressions suitable for transformer design purposes. These models are derived from 2D and 3D finite element simulations. The magnetic flux distribution in the transform...

Influence of Antimony on the Texture and Properties of 2 % Si , 0 . 3 % A 1 Steel for Non - Oriented Sheet

The effect of additions of antimony (0.05% Sb) to silicon steel on the improvement of the electrical properties of non-oriented steel sheet was investigated. Measurements of surface segregation of Sb were performed under UHV conditions in the temperature range from 450 to 900 OC, using AES and TDS. Maximum equilibrium surface segregation of antimony was determined at 700 OC. At higher temperatu...
