AC voltage standards
consistency of standards - Opis:
- In 2014 at the Silesian University of Technology (SUT) two calculable thermal AC voltage standards were developed. AC-DC differences of those standards were calculated from an appropriate mathematical model in 1 kHz – 1 MHz frequency range and determined experimentally in 10 Hz – 1 kHz frequency range. The correctness of determination of the AC-DC differences of the standards were verified by comparing them with a thermal converter calibrated in an external laboratory. That calibration confirmed the correctness of the determined AC-DC transfer differences. Lately, a comparison with a third laboratory has been performed. The paper presents results of these comparisons and a discovered inconsistency between the calculated AC-DC transfer differences of the SUT calculable thermal AC voltage standards and the AC-DC transfer difference of the AC voltage standard from the third laboratory.
