Waste inductance is a grid element that is modeled by a magnetic field that does not participate in the transfer of energy between transformer windings. The scattering inductance is modeled at the transformer model level by a magnetic field caused by primary and secondary currents, which is not aligned with the coils of other windings. Waste inductance is by its nature neither desirable nor undesirable, in some applications it seeks to achieve as large as possible and in others as small as possible. Transformers with a short-circuit voltage of between 5 and 15% are usually selected From the graphical representations of the results of the simulations in Ansys, the dissipated magnetic flux of the transformer is clearly visible. The program enables fast and simple modeling of the magnetic field of various transformer designs. Also for different current-voltage conditions (loads). The user is able to customize the graphical views in various ways. The best example of when we want the maximum magnetic flux to be the largest is with an arc welding transformer to limit the short-circuit current to the amount required for the electric arc to burn normally. This final paper clearly describes the foundations of the laws of electromagnetism and the broader picture of wasteful inductance. The scattered magnetic inductance of the transformer depending on the application must be treated with great care. The Ansys program provides users with great opportunities to create models, graphs, diagrams, etc. With the help of these laws of electromagnetism, mankind has learned to apply and make the greatest invention to the power system.
