Calculating impedance for a three wdg xfmr
Calculating impedance for a three wdg xfmr
(OP)
See attached pdf file for the nameplate information.
I have a 3 winding transformer which has its each low side terminals connected to one 500kw inverter. I am used to seeing a pri-sec, pri-ter, and ter-sec impedance values for three winding transformers which I use to model it using PTW. How do I find out these impedance values based on just one impedance value shown in the data sheet?
Thank you for the time.

Test report would definitely help. I'm sure someone at ABB plant can help you. The trick is tracking down that person.
