The aim of this study is to design and magnetic analysis of a grounding transformer in order to prevent material damage caused by phase-ground faults that may occur in wind energy systems. A zig-zag transformer is designed with a new winding design technique, different from the traditional zig-zag transformer design. Due to the lack of analytical formulas, finite element analysis (FEA) is used to calculate leakage reactance of designed transformer. The designed zig-zag transformer is analyzed in the ANSYS Maxwell environment. The proposed grounding transformer for wind power systems is investigated in terms of 3-phase 3D leakage reactance, 1-phase 3D leakage reactance, core losses of 3D, core losses of 2D, and flux density. The obtained results showed that the designed zig-zag transformer is compatible with wind power systems.
