Evaluating Uncertainty of Alternating Current Reproduction Using National Standard

• Abstract:

  The research work was aimed at improvement of metrological service of Ukraine, i.e., to solve a problem of metrological support of the production and operation of the thermoelectric converters, precision meters and sources of alternating current. A method of comparing alternating current with equivalent direct current using the precision thermal converter and shunts was selected to build the standard, and the composition of the standard was established. A functional diagram of the standard was developed to disseminate an alternating current unit. The main sources of measurement uncertainty of this unit are a combination of Type B standard uncertainty of both a thermoelectric converter and a precision shunt. A contribution to combined measurement uncertainty of both the set of measures of electrical resistance and the meters of an output voltage of both a measure of electrical resistance and a thermal converter was analyzed.
