Negative Phase Sequence

Cameron O'Connell
I have been looking at a calculation formula someone sent to me for the negative phase sequence of an unbalanced three-phase generator. the calculation looks at the three loads applied to L1,L2 & L3. the formula gives the negative phase sequence which should not be more than 20% of the rated maximum current.


I have searched low and high for the source of this information and I can't find it anywhere, would anyone know if it is correct and/or where the information comes from as i have no contact details form the person who originally gave it to me.

    Hi All,


    Thanks again for the info.


    I have been reading through the regs and Annex A722 (Informative) - 722.1 opened up in front of my eyes and I couldn't believe it.


    The same equation is written but slightly transposed.


    I hope this might help someone looking for info on this in the future.
