An international comparison of 50/60 Hz power (1996-1999)

An international comparison of 50/60 Hz power is described. The traveling standard was an electronic power transducer that was tested at 120 V, 5 A, 53 Hz, at five power factors (1.0, 0.5, and 0.0). Fifteen National Metrology Institutes from six metrology regions participated in the comparison.
