Abstract


Has entered the stage of practical work on the development of new electronic transformer , electronic transformer calibration increasingly urgent demand . National high voltage metering station Electrical Equipment Quality Inspection and Testing Center with reference to the international standard IEC60044 - 8 preparation of electronic current transformer electronic transformer calibration specification , the establishment of electronic transformer calibration system to achieve the unified calibration standards and methods purposes. The calibration system including analog and digital outputs of two parts . This paper discusses the the electronic transformer digital output part of the calibration system to establish . The digital output portion of the calibration system in a conventional electromagnetic transformer as standard to standard electromagnetic transformer analog output after A / D conversion , and then compares the digital output of the transformer under test . The calibration system consists of standard electromagnetic transformer , standard A / D converter , the measured electronic transformer , PC , calibration software . The paper introduces the digital output of the electronic transformer , and the digital output of the combined unit , and electronic transformer calibration of the digital output section . In order to calibrate the system to meet the requirements of the standard digital output , the thesis requirements in accordance with IEC standard digital output as well as a combined unit with secondary equipment communication problems , and the development of a combined unit . In the establishment of part of the calibration system , the paper describes the analysis of the standard traceability , error theory , research and analysis of delay calibration system of absolute comparative figures for the output of the algorithm . Finally, analysis of the sources of uncertainty of the calibration system , and gives the expanded uncertainty of the school barebones . Nominal frequency 10kV to 500 kV / electronic voltage transformers in the range of 20% to 120% of rated voltage range 5A to 5000A electronic current transformers in the range of 5% to 120 % of rated current , the school barebones expansion Uncertainty satisfy the requirement of 0.05% ratio error and phase error of 2 stars , 99 % confidence probability .
