The State Enterprise “Ukrmetrteststandard” has created and approved the AC secondary standard of the unit of coefficient of large-scale transformation voltage, which has been added in 2010 year to the State Register of the first and secondary standard units under the reference number # ВЕТУ 08-05-07-10. The metrological performance capabilities of standard units are determined by the International Database of countries potential in calibration and measurement in case if the results of measurements appraise by measurement uncertainty. The methodical approach in transformation of errors characteristics of the secondary standard units in uncertainties characteristics is showed.
