- Abstract:
- The article describes results of an interlaboratory comparison of instrument current transformers performed in the Czech Republic. An operating instrument current transformer with ratios 400 A/5 A and 800 A/5 A has been used by this comparison. A common instrument transformer has a big dependence of errors on burden and its phase displacement. This dependence is also illustrated. The various results are compared and determined their differences for single laboratories.
