Show affiliationsElectrical standards of low-frequency (50/60 Hz) power at 15 national metrology institutes (NMIs) were compared to establish the relationship between the electrical units at these laboratories. The results of this comparison are described. The differences between each laboratory's values and the reference values were within the measurement expanded uncertainties at a coverage factor k = 2.
