Abstract
This paper describes calculation of zero sequence impedance in three phase, three leg core type
power transformers using 2D and 3D finite element method (FEM) calculation on example of 100 MVA
power transformer. Paper also describes how winding connection and arrangement affects the size and
calculation of zero sequence impedance.
Keywords
zero sequence impedance; zero sequence reactance; power transformer; finite element method; FEM
