Abstract
This work deals with low-loss magnetic properties of electrical sheets for transformers cores. The work is divided into six parts. The first part presents basic magnetic quantities, followed by the magnetic properties of substances and materials. The third section describes the production technology, basic production allocation base sheet and strip, and specifies critical properties of these sheets. The fourth part deals with measurement and measuring instruments. The fifth section describes the experimental analysis of sheet thickness. The last part is evaluated measurements.
