What is the meaning of positive, negative and zero sequence components of voltage or current?
How does the positive sequence component differ from the negative sequence component?
The positive sequence represents the three-phase system in a balanced condition, meaning that the magnitude and phase angle of the voltages or currents are equal. The negative sequence represents the three-phase system in an unbalanced condition, meaning that the magnitudes of the three voltages or currents are equal, but the phases are shifted by 120 degrees. In other words, the negative sequence reveals a deviation from balance, which could be caused by a fault or unbalanced load.
