Intercomparison of DC voltage ratios up to 1000 V

Project Description

This comparison, which corresponds to the regional key comparison EUROMET.EM-K8, aims at verifying the agreement among Euromet laboratories in calibrating the voltage ratios of a Datron 4902S DC divider.

After the problems encountered at the beginning of the year 2000, which forced the pilot to suspend the circulation of the standard in order to check its behaviour, the comparison was resumed in September 2001 and the circulation ended in January 2002.

Control measurements are now in progress at IEN, also to evaluate the power effect on the standard in order to establish the pilot values at low voltage. The Draft A report will probably be ready not before June 2002.

Final Report 2003-12-31

The comparison has been finished and the results are available in the KCDB.
