- Abstract:
- At IEN the application of new procedures for the calibration of ac voltages in the millivolt range is now being developed. In this paper a specific method based on a high precision inductive divider and wideband ransformers is analysed. The experimental determination of the transformer parameters shows that the generation of calibrated ac voltages is possible with an uncertainty better than 50 parts in 106 down to 10 mV.
