Harmonics in supply voltage or load current in a transformer have undesirable effects on the core and windings. As the harmonic content increases, higher core loss and eddy current loss in the windings results in higher operating temperatures. It causes magnetic flux density in the core to increase and shifts the operating point through the saturated region. This phenomenon is mostly taught in undergraduate education as theoretical information. However, as a difficult concept to understand, harmonics phenomenon might be taught by using experiments for active learning, visualizing the effects in a laboratory setting, and making the connection between theoretical and practical applications for deeper and meaningful learning. In this study, a teaching method for effects of harmonics is proposed and phase shift between the fundamental and harmonic component of the supply voltage on the transformer B–H characteristic in a laboratory application is introduced by an experimental work performed on toroidal transformers. Feedback from students shows that the proposed method is very efficient and useful for students to better understand the effects of harmonics on the transformer cores.

-The paper is devoted to the development of specialized software for simulating the electrodynamic processes in induction motors. This software includes both the graphical interface and the computational modules based on quasi-3D finite element modeling of electrodynamic processes as well as 3D finite element modeling of the magnetic field in order to take into account the end-zones influence on the values of the magnetic fluxes and rotating torque. The numerical data are compared with the experimental data. The results of the simulation of transport vehicle acceleration for different modes are presented. The proposed software allows the engineers to perform the quasi-3D modeling of electrodynamic processes in the induction motor even if they are not experts in numerical methods.
