Abstract
The paper discusses the magnetic flux density distribution in medium power transformers core. Three-phase
transformers are usually made of grain-oriented electrical steel characterized by anisotropy. Core losses, among other things,
mainly depend on the grade of material. The selected results of calculation and measurement of no-load losses of medium
power transformers have been shown.
Keywords
