How to find zero sequence impedances for 3winding transformers
(OP)
Hi All,
I am working on 3 winding transformers. At present I have the primary-secondary, pri-tertiary, and sec-teritary positive impedance from the manufacture. But they dont provide any zero sequence impedances. Can anyone help?
The 3 winding transformer arrangment is DDyn11.
Thanks
