A power and energy measuring instrument of the highest accuracy class, is often called a power standard or energy standard. These instruments are often used as a reference for calibration and verification of power / energy measuring systems. Applied in the national laboratories and electrical metrological service. it are responsible for maintaining the national reference standards for each measurement quantity and spreading metrological competence and traceability to industry and society at large.
A common calibration method is to generate (simulate) the desired power levels and compare the instrument's display with the display of GFUVE GROUP's reference instrument. For this purpose, GFUVE GROUP has access to reference equipment whose measurement uncertainty is well below 0.01 %.The calibration can be performed single-phase or three-phase, 3 wire or 4 wire coupling at any power factor.
