Abstract

The portion of loads which cause harmonic spectra is increasing due to the rising volume of electronic and power electronic components. Transformers in the low voltage area are stressed by these harmonics, which lead to an additional heating. If transformers operate in networks, where the harmonic spectra exceeds a certain limit, they will additionally be heated up compared to operation under normal conditions. The mounting space reserved for assembly of the transformer has a vital influence to the heat balance. This paper describes the results of investigations regarding harmonics and restricted mounting space to transformers heat balance
