| Zusammenfassung | This paper describes the setup of an active lowvoltage capacitor designed to realize capacitive voltage dividers by means of compressed-gas, high-voltage capacitors for rated primary voltages between 5 kV and 800 kV / √3. In the future, this divider, which has a negligible voltage dependency and low phase errors around 50 / 60 Hz, will be used to realize a fundamental step-up calibration method for the standard voltage transformers at PTB. Initial measurements indicate an attainable uncertainty of below 2 ppm for the ratio error (short-term) and 1 μrad for the phase displacement of the capacitive divider. |
