Testing of Merging Unit comprising voltage and current transducers in the set
Ziegler, Jiří ; Drápela, Jiří (referee) ; Topolánek, David (advisor)
The diploma thesis is focused on testing and design of a test system of merging unit which provides digital output according to IEC 61850-9-2. The parameters and distinguishing features of the test system are based on functional principles of merging unit and standards dealing with the testing of transducers. The proposed test system is based on modular PXI Express system from National Instruments. The desing is performed with respect to the possibility of generating test signals and measurements for voltage up to 38.4 kV and current up to 2000 A. The proposed test system meets the criteria for testing transducers of accuracy class up to 0.5. Assuming of calibration designed test system as a whole, this test setup has the potential to meet the technical requirements for testing transducers of accuracy class up to 0.1.
