Bilateral comparison of AC/DC transfer standard at low voltages

Project Description

The Federal Office of Metrology and Surveying, Austria (BEV) and the Bulgarian Institute of Metrology, Bulgaria (BIM) will perform a bilateral key comparison “AC/DC voltage transfer difference at low voltages". The results will be linked to those of EUROMET.EM-K11 (EUROMET Project No 464). EUROMET.EM-K11 results are linked to those of CCEM-K11.

  • BEV and BIM jointly coordinate the comparison: BEV supplies travelling standard
  • BIM writes a technical protocol and management tasks, schedules organisation
  • BEV references measurements, analysis and reporting tasks

The AC/DC voltage transfer difference of travelling standard should be measured at:
Nominal voltages: 100 mV, 10 mV and 2 mV; Frequencies: 1 kHz, 20 kHz and 100 kHz
