Negative Phase Sequence

Cameron O'Connell over 4 years ago

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.

This is not my speciality but does this help? What is negative sequence current and how does it affect generator work | EEP (electrical-engineering-portal.com)

The heating effects need to be kept low to prevent generator damage. Perhaps the 20 per cent or less is a rule of thumb thing.

Balanced loads ensure better efficiency.
