need help in this instrument transformer question

[damani]

i'v rresearched on it. Not completely sure if wt i have is correct. Though its not complete. : for current transformer; Variables for Consideration Current Range Overload current rating Primary conductor opening Sensitivity - volts per amp Burden VA and resistance Internal / external termination Frequency response Accuracy and linearity Ambient temperature / allowable temperature rise Dielectric / insulation resistance Cost....... I'v still not gotten for voltage transformers. Hoping y'all will help mi out with ideas and reference

Hi,

Not sure if i understand what you are asking here. You seem to have most everything covered.

Temperature response is a concern for most any part we come across. Input/output voltage limits too. Limits on the current handling as you know.
Isolation voltages DC and AC input to output, input to ground, output to ground, etc.
Leakage inductance.
Transfer ratio (turns ratio).
Signal distortion.
Primary excitation current.
