Annotations languages:

The State Standard of the electric power and power factor units is functioning in State Enterprise “Ukrmetrteststandard” for the metrology providing of high-fidelity measurement instruments of electric energy. An estimation of measurement uncertainty at calibration of power factor working standards with using indicated State Standard is shown.
