Abstract
This work describes magnetic properties of modern electrical sheets for transformers cores. There will be measured and compared lent core transformers, and therefore it is necessary to know the details of magnetism, magnetic properties, and magnetic measurements. Work will be divided into three main parts. The first part is a theoretical analysis that includes familiarization with the applied magnetic quantities and transfers. It further describes the magnetic properties of materials. The next part is a description of the basic and specific properties of electrical sheets, including a relatively detailed manufacturing process. Next is an analysis of methods for measuring the magnetic properties. The second part is a description of sample preparation lent core transformers to measure their performance. The third chapter is the measurements and graphical analysis of core samples of type transformers. The last part is an evaluation of the results and conclusions.
