Information × Registration Number 0205U007152, 0103U000196 , R & D reports Title System of the reproducing the master voltage of alterneting current of the low frequency. popup.stage_title Head Tuz Julian Mikhailovich, Registration Date 23-12-2005 Organization Radioengineering Department of National Technical University of Ukraine "K P I " popup.description2 The system for the reproduction of AC voltage unit at low frequencies is created. The system is based on the synthesizer of purely sinusoidal voltage and the converter of voltage amplitude to time interval. The errors of the converter are less than several ppm of the voltage amplitude. Working in the automated mode, this voltage source passes the voltage unit to thermoelectrical comparators that are the basic parts of modern voltage standards. The system is controlled by PC via IEEE-488.2 interface. The system with its full complement may be applied for the voltage unit transfers to the national, working and basic reference standards. The simplified variant of the system may be applied for the testing and calibration of working measurement instrumentation. This work is implemented in the metrological service of branch ministry. The system designed allows our country to become independent from expensive borrowing of voltage unit from foreign countries. Product Description popup.authors popup.nrat_date 2020-04-02 Close
