摘要：
A mains-frequency power standard traceable to voltage and impedance standards has been realised. Standard uncertainties are 26 mu W/W at unity power factor, and 18 mu W/W of apparent power at zero power factor. A power bridge balanced to 0.2% is augmented by FFT analysis of samples of the detector voltage, eliminating harmonics and drift in the test sources.
