Negative sequence voltage
The adverse effects of unbalanced voltages on induction motors stem from the fact that the unbalanced voltage breaks down into two opposing components that can de described using a method of symmetrical components.
Through the use of symmetrical components, we can describe an unbalanced three-phase system of voltage or current phasors using three balanced systems of phasors termed positive, negative and zero sequence.
