CCE intercomparison of AC-DC transfer standards

J.P.M. de Vreede
1993 IEEE Transactions on Instrumentation and Measurement  
Results are consistent within 10-20 ppm at low voltage and frequency, but differ by up to 100 ppm at high voltage and frequency.  ...  A worldwide intercomparison is described covering both ac voltage and ac current measurements in the frequency range from 40 Hz to 1 MHz.  ...  The scope of the comparison was to cover the usual range of ac-dc standards available at national standards laboratories.  ...

CCEM-K5 Comparison of 50/60 Hz power

Nile Oldham, Thomas Nelson, Nien Fan Zhang, Hung-kung Liu
2003 Metrologia  
To better link these comparisons, second measurements were performed at NRC in 1998 and at PTB in 1999. Measurements performed in 2000 were retests requested by the participating NMIs.  ...  Electrical 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.  ...  Synchronous with ac power stability 1.33 1.33 1.33 5.
