- W3188778025 abstract "According to Ukraine’s desire to integrate into global international structures the recognition of the measurement results in the measurement field of electric AC voltage is considered to be necessary. The storage of a unit of electrical AC voltage in accordance with the guidelines helps to meet this demand. One of the main metrological characteristics of any national standard is instability for the year. The article presents the results of fifteen-year work on the annual determination of the instability for the year and the proper measurement uncertainty of the national standard of electrical AC voltage unit from 0,1 to 1000 V in the frequency range from 10 Hz to 1 MHz, wich was developed and stored in the SE «Ukrmetrteststandard». This metrological characteristics are determined in accordance with measurement procedure developed by SE «Ukrmetrteststandard». The AC-DC difference measurement results of a precision thermoelectric converter PMJTC, developed at the National Metrology Institute of Germany PTB, are compared every year. During the measurement process a reference thermoelectric comparator 792A, manufactured by Fluke Corporation, is used. An analysis of some metrological characteristics of this Ukrainian national standard was made on the basis of obtained data array. The compliance of the investigated instability for the year of this Ukrainian national standard with the requirements of normative and operational documentation is also established in the article." @default.
