N2 - This paper aims to estimate the electromagnetic field distribution in a simplified transformer through two-dimensional (2-D) finite element analysis. We create two datasets, namely the original dataset (OD) to simulate grayscale images and the new dataset (ND) which incorporates distinct physical properties of materials. These datasets are helpful to investigate the impact of different data types on deep learning. In order to enhance the accuracy of estimation, we compare the performances of two convolutional neural network (CNN) architectures: U-net and its improved version, U-Resnet (which incorporates residual blocks from ResNet). Additionally, we introduce a specialized loss function, Add-RMSE, which is better suited for dense regression problems, thus improving the prediction accuracy. The effectiveness of our proposed method is validated through test experiments, where we analyze the estimation results obtained.
