| Zusammenfassung | This paper present a new measuring method which allows the loss factor of 1 μF capacitors to be derived from the calculable time constant of a 200 Ω AC resistor of bifilar structure. The method combines elements of the traditional bridge technique (Thomson balancing and Wagner earthing) with the digital synthesis of signals and their sampling using the discrete Fourier transform (DFT). The method allows the loss factor to be determined with an estimated standard uncertainty of measurement (k = 1) of 2×10-6 |
