How to connect Dyn1 and Dyn11 power transformers in parallel operation? 2

[GRAEE]

Hi everyone,

Would like to ask your ideas on how to do parallel operation for two transformers with different vector configuration, Dyn1 and Dyn11.
If possible, what are the connections to be done?

Regards,

GRAEE

I would appreciate if you can recommend some references related to this parallel operation.

Thanks.

I've posted this a few times over the years, and apparently it needs another airing out.

This was the latest version I did, a few years ago.

Dy11 to Dy1

If I read the question as posed then it is not possible to parallel without modification as suggested by Sibeen
