Thanks.
I can take the test reports from manufacturer if I buy new transformers. Actually, I have several projects, some of them involve old transformers and test reports inaviable.
Let assume that a transformer has very good accuracy near zero load. But it is not a decision of my problem/
I...
I live in Russia and we have own standards, but they were close to IEC. To bemore precisious, our standard for CTs based on IEC 44-1:1996
I think it not very important. There are similar statements in IEEE standards, too.
I have a problem. I'm working on a design an AMR (Automatic Meters Reading) system. Our local standard for current transformers (wich are very close to IEC and IEEE standards) says that secondary load of a transformer must be between 25 to 100 %. If not, the transformer doesn't work in raited...
