Comparison of the measurement of current transformers (CTs)
This is a follow up to project 473.
All participants have now made measurements after a substantial delay in one country. The transfer standard has now returned to the UK.
It has been agreed that the Draft A report should be an extended version of the one from project 473. A combined Draft B for the 2 comparisons will be produced. The same support group as for project 473 will be used. They are IEN (Gabrielle Crotti) and PTB (Klaus Schon).
Final Report 2009-03-31
