A HIGH CURRET SELF-CALIBRATIG STANDARD-TRANSFORMER

• Abstract:

  This paper presents the development of a selfcalibrating transformer for using as a primary standard in the Uruguayan National Metrology Institute. Nominal ratios go from 5 A/ 5 A to 2000 A/ 5 A. The ratio of the transformer can be changed using the same primary windings, so that there is no appreciable effect on the errors for different ratios.
