Abstract

This bachelor thesis deals with the theoretical description of the transformers, but especially 1 phase shifters and running in idle and idle currents. Introductory chapter describes the complex issues of transformers, their principle of operation, construction and purpose of use. The following chapters are intended to 1 phase transformer failed, there are described the electromagnetic and structural properties. A separate chapter is devoted to current issues open. It describes the theoretical assumptions for the calculation of current methods of determining the effective open magnetizačního value stream of the magnetic circuit, the magnetisation fruitless work and determination of active ingredients idle current. Part of this work is the measurement of currents in the open laboratory, comparison of measurement results shown in the graphs and draw conclusions from this measurement.
