| Zusammenfassung | For the determination of the unit Henry of the inductance at PTB a Maxwell-Wien bridge has been developed. The advantage of this type of bridge is that the first order equation is independent of frequency and therefore works well in a frequency range from 50 Hz up to 1MHz. The bridge includes a Wagner device to eliminate stray and cable capacitances. It is necessary to consider the frequency dependence of the used primary standards to decrease the desired uncertainties of the determinated unit Henry. |
