What are the impacts of specifying multiple temp. rated transformers with respect to impedance and fault current? Here's an example:
80deg/150deg
AA/AA/FA
3000/3990/5000kVA
%Z = 5.75
What are the effects on fault current when operating above the 3000kVA base rating continuously? Will the impedance change greatly or only slightly?
Detailed calculations would be done later in design, but I would like to use approximation methods at the beginning of schematic design to anticipate equipment ratings.
Any thoughts or white papers that address this issue?
Thanks for the help.
