An international comparison of de voltage ratio for voltages up to 1000 V h
as been started. It is one of the key-comparisons of electrical quantities
selected by the CCEM in order to foster mutual recognition of the national
measurement standards and calibration certificates issued by National Metro
logical Institutes, The results of the work carried out by IEN, the pilot l
aboratory of the comparison, in order to characterize a voltage divider are
reported. Drift and dependence on ambient conditions of this divider were
found low enough to justify its use as the traveling standard in the compar
ison.
