An international comparison of 50/60 Hz reactive power meter calibrations between NRC, NIST, CENAM, NIM, and KRISS

A number of international comparisons of active power meter calibrations were conducted in the past. This paper addresses the international comparison of reactive power meter calibrations at 120 V, 5 A, 50/60 Hz, and power factors 0.5 lead/lag, and zero lead/lag, between 5 NMIs; 3 from the SIM metrology region (NRC, NIST, CENAM) and 2 from the APMP metrology region (NIM and KRISS).
