The evolution of teaching methods concerned with electrical engineering enables the development of new measurement stands or the improvement of existing educational methods. The advancement in engineering equipment is affecting the formation of new methodologies in teaching. Nevertheless, new educational techniques should be implemented by taking into account understanding of a physical basis of studied phenomena. This goal may be achieved via a combination of practical exercises conducted on testing stands, during evaluation, by means of modern computerized tools. In this paper, we described the combination of a numeric study of electric field (EF) distribution and an improved analog method analysis performed on an educational set‐up. For an effective understanding of technical problems of high‐voltage (HV) and medium‐voltage technology, the presented educational tool combines an experimental method of EF equipotential line mapping and EF strength determination with an improved analog method of EF strength inside the HV insulation system, which is determined by means of differential equation calculation implemented on the developed software. For fast verification of the results, computer simulations were applied. It allows for presenting the strong and weak points of both used methods. Analyzed models reproducing real devices were built on different scales; thus, achieved results reflect the real values and may be used for study help during seminars.
