EUROMET Projects 473 and 612: Comparison of the measurement of current transformers (CTs).

The Euromet comparison titled 'Comparison of the measurement of current transformers' was carried out over two projects with NPL as pilot laboratory and thirteen other participating European National Measurement Institutes (NMI). Current transformer measurements made by the participating NMIs support a large number of measurements made in the electrical generation, supply and distribution industries in their own countries. They also support many transformer manufacturers who rely on national standards as a source of traceability.
