Popis: | Metrological evaluation of electrical power quality signal generator, designed for reproducing the standard power quality disturbances, is presented in this paper. This generator is functionally based on the virtual instrumentation software, data acquisition card and power amplifier for scaling the output voltage to the nominal power line voltage level (230 V). The realized computer-based signal generator can be used as suitable and cost effective alternative to the various instruments for testing the power quality meters and analyzers. Metrological assessment of signal generator includes calculation of measurement uncertainty components and final presentation of measurement uncertainty budget. Procedure for calculation of Type A, Type B, combined and expanded measurement uncertainty, according to the Guide to the Expression of Uncertainty in Measurement, is proposed. |
