Testing metering current transformers with CT Analyzer

[@omicronenergy]

Dear สุริยา อุดทามุล, It is not necessary to connect a real burden to the secondary side, because the CT Analyzer simulates the burden impedance based on a mathematical model. Since this seems to be an enquiry that has already been answered by our technical support team, we kindly ask that you contact your local support team for detailed information, in case you haven't received a response yet. Best regards, Your OMICRON Team

Thanks for the concepts you have shared here.

Last month I tested turn-ratio of metering CT class 0.2S FS10 with CT Analyzer, first testing the result wasn't pass so next testing I connect real burden(variac),about 50% of rate burden, to secondary side of CT the result was pass. This is my question ? 1. Do I must connect real burden at secondary side of CT when I test turn-ratio of metering CT ? 2. How does burden simulate in CTa work ? Why in can't use in this case? Best Regards.
