Abstract

This thesis deals with the comparison of the different characteristics of current measurement of an instrumented current transformer and a Rogowski coil current sensor, which are demonstrated through a laboratory task in the laboratories of the University of Mining - TUO. In the theoretical part of this thesis, the basic distribution and analysis of the properties of the selected current instruments are described. The theory also explains the standardized accuracy classes and basic definitions related to current instruments. The practical part focuses on the design of the basic circuit of the laboratory task and its design part. It also includes reference measurements along with the practical implementation of the laboratory task. The practical part describes the creation of all the necessary instruments for measurements on the instrumented current transformer and current sensor. The practical part describes detailed measurement instructions with a sample protocol according to the text assignment. In the appendix, all the necessary materials for introduction into the classroom are provided.
