System for measuring properties of electronic transformers

The purpose of this thesis was to study the properties of electronic current and voltage transformers, choose the method for temperature cycle accuracy test and the development of the measuring software. Measuring software was realized in LabVIEW version 8.2. The first part describe the topic of this thesis. The second part describes various kinds of sensors and describtion of functions and specifications. The third part describe programming system LabVIEW. The fourth describe design of connection supply and measurement part of circuit. The fifth part describes used instruments. The sixth part is about used methods measuring. In the seven part is the description of the functions of this program and its control. In eight part is evaluated measurement uncertainty. In the last part are shown examples of the application program
