W artykule przedstawiono analizę harmoniczną drgań i hałasu emitowanego przez rdzenie transformatorów pracujących przy podmagnesowaniu składową stałą strumienia. Przedstawiony został układ pomiarowy do badań wibroakustycznych rdzeni modelowych w w/w warunkach pracy. Uzyskane rezultaty zostały uzupełnione odpowiednimi wynikami pomiarów dla trójfazowych transformatorów zasilających układy prostownikowe...
This paper presents an analysis of the vibrations generated by models of transformers, made up of metal sheets from different manufacturers. To analyze the vibrations the experimental investigations from different transformers models were carried out. Additionally, the influence of submagnetizing of the core with a DC component on the vibrations of model cores was examined. The measurements of amplitudes...
