Question: "Zero Sequence Elimination For Differential Protection"

[rayas91]

Hi all friends,
Do you have a circulating fault currents scheme in Star/delta, Delta/star, star/star transformers for differential protection? Circulating directions / current magnitudes...
Also calculations which differential relay calculate.....There s no any details in manuals.

Thanks a lot.
