Just compare the CT sizes with the ones that have the name plate on it. Each CT have different sizes for each application.

Try a burden test, find the point at which each coil fails to perform up to standard, and compare your results to a similar transformer that has a nameplate.
Are the terminals also not marked? Perhaps the transformer is in service and you don't want to get close enough to visually inspect the nameplate and terminals?

Thank you,actually I was also thinking a VA characteristick test to find the linearity; metering CT expected to have more linear than the protection but how I identify the PS core.
Number one on your list is, "Very carefully". CTs have a habit of generating very high voltage when cut off from source. The voltage induced into the high voltage side, with current, can produce and output voltage of up to 1 MV (million) on the low voltage side. I would send the Ct's back or send them to someone who has experience with such an item.
