The leakage impedance of a transformer comprises of
resistive and a reactive component is one of the most significant details that
have a substantial impact on the overall design. The reactance of the
transformer windings is an important component of the design which has a direct
effect on its operation. Reactance is used for the computation of not only the
transformer equivalent circuit parameters but also for designing its
protection. Roth’s method, Rabin’s method, method of images, and classical
methods are the traditional methods used for its calculation. In Rabin’s
method, we assumed that current density depends on the axial position. Roth’s
methodis used for calculating the leakage reactance of windings that have
asymmetrical arrangement. The method of images used the coordinate system. The
finite element method can be used for the calculation of transformer reactance.
In the industrial revolution, all manufactured transformers would be evaluated
through their 3D design and performance analyzed by computational methods. In
this work, the reactance calculated by the finite element method has been
compared to that calculated by the classical method. The calculated values of
energy stored in the windings and other parts and the reactance can be found.
