Abstract

The paper describes the systems, the standards and the procedures developed at IEN for the precise measurement of ac voltages in the millivolt ranges. Two different methods based on resistive dividers and wideband transformers have been developed and are applied for the measurements of respectively the ac-dc transfer difference and the ac voltages down to 1 mV.
