Calculating %Z from %IZ
Calculating %Z from %IZ
(OP)
I recently ordered a few 208V to 208V isolation transformers. I asked the manufacturer for the impedance data. I was given %IZ, %IX, and X/R. When I calculate the %Z, the results are larger than expected. I may be doing something wrong. Can anyone tell me how to calculate the %Z from the provided data? These are 15kVA to 150kVA transformers.





RE: Calculating %Z from %IZ
Then use the X/R ratio and Pythagoras' theorem.
