| Popis: | A low-frequency AC Power Standard based on the Programmable Josephson Voltage Standard (PJVS) has been developed at the National Research Council (NRC) of Canada. At the step voltages, PJVS provides quantum accuracy. Differential digital sampling is used to extend the quantum accuracy to the AC Power Standard output voltage and current, nominally 120 V and 5 A. The paper describes the evaluation of the power standard and its components. 2012 Conference on Precision Electromagnetic Measurements (CPEM), 1-6 July 2012, Washington, DC, USA Series: CPEM Digest |
