An effect of manufacturing conditions on the properties of a 250kVA three-limb three-phase distribution amorphous transformer

Abstract The research results for different stages of production of a three-phase 250 kVA distribution transformer using three-limb amorphous magnetic core have been presented. The core is made from six frames wound from 23 μm thick Metglas 2605 TCA ribbon. Magnetic characteristics for the frames and three-limb core were measured. The 250 kVA distribution transformer was manufactured.
