Abstract

Measurements were carried out at the Czech Metrology Institute (CMI) and at the Ukraine National Institute Ukrmetrteststandart in the range of transformation ratios up to (6-35) kV/ 100 V, and the results were compared. The results are interesting due to the fact that the two laboratories used different methods for determining the ratio error and the phase displacement. The results are also atypical due to the fact that one value of the burden of the transfer transformer is approaching zero.
