Positive sequence component: It represents three equal phasors, phase displaced by 120° and has phase sequence same as the original phasors.
Negative sequence component: It represents three equal phasors, phase displaced by 120° with each other and has phase sequence opposite to that of the original phasors.
Zero sequence component: It represents three equal and parallel phasors with zero degree phase displacement.

Explanation:
Negative sequence components:
- Negative sequence components are phasors with equal magnitude but are displaced from each other by 120 degrees with reverse phase sequence as compared to that of the original.
- These components represent unbalanced conditions in the system, such as when there is a fault in one of the phases.
- Negative sequence components can cause overheating of motors and generators, as well as other equipment in the system.
- By analyzing negative sequence components, engineers can identify and mitigate problems in the system before they cause damage.
In contrast, positive sequence components represent balanced conditions in the system, while zero sequence components represent conditions where all three phases are in phase with each other. Unity sequence components do not exist in power systems.
