https://doi.org/10.4467/2353737XCT.16.262.6061The paper summarizes the power loss results in induction machines supplied with distorted voltage. The voltage waveform contained the fifth and seventh harmonics components of adjustable level in the range of 0% to 30%. The influence of the harmonic content on the core and windings losses is of particular interest. The paper investigates the additive impacts of basic and additional losses resulting from distorted power supply conditions.

https://doi.org/10.4467/2353737XCT.15.025.3825This article presents the results of modeling the phenomenon of free and forced magnetization in three-phase, three-legged transformers. The no-load state of the transformer has been modeled using the program including a circuit model of the transformer. The results obtained have been compared with measurements carried out in the laboratory for the various circuits connection of the transformer.
