AbstractA reactive power standard, based on the current comparator power bridge, established at CEPRI, for calibrating active/reactive power/energy meters under sinusoidal conditions is described. It allows calibration of active/reactive power and energy meters at voltages between 60 V to 600 V and currents between 0.1 A to 200 A, any power factor from zero lag through unity to zero lead, and test frequencies of 45 Hz to 65 Hz. The Type B uncertainty of the reactive power standard is estimated to be 30 μvar/VA at k = 2. A comparison of reactive power meter calibrations between CEPRI and NRC will also be presented and discussed, including the sources of errors and corresponding uncertainties.
