200 kV reference dividers will be transported from the participating laboratories to RISE in February/March 2022 to compare their high voltage arm resistances. Participants shall define the resistance of the reference branch high voltage resistor of their divider using existing home laboratory procedures before sending the divider for comparison measurements at RISE. Each participant shall repeat their home calibration after the divider has returned after comparison.
The pilot laboratory is RISE (Sweden).
This comparison is carried out simultaneously with the EURAMET project High voltage comparison of DC ratio.
