摘要：

The paper presents results of a systematic finite element (FEM) simulation of transformer susceptibility to geomagnetically induced currents (GIC). DC saturation patterns for five different transformer core designs are examined using FEM; magnetic fields along various traverses are provided. Impedance matrix entries of a single phase transformer are compared for normal and dc saturation operations. The study aims to contribute in the understanding of fundamental transformer magnetization mechanism under GIC.
