| Popis: | A 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. 2012 Conference on Precision Electromagnetic Measurements (CPEM 2012), 2012-07-1 - 2012-07-6, Washington, DC, USA |
