# Is the zero sequence component considered balanced?

how is the zero sequence component is balanced while the three vectors are inphase and not displaced from each other by 120°?

Isn't the definition of a balanced system is one in which the magnitudes of all phases are equal and are spaced out by 120°?

The confusion came from the book below:

• It's using a different meaning of "balanced", I suppose – user253751 Feb 18 at 9:28
• "Equi-spaced" does not necessarily mean that the angle is strictly greater than zero, it can be zero. It means that the differences between them are equal. So the assertion is true: they are the same magnitude, and same angle, which means they are equi-spaced at zero degrees difference between them. – a concerned citizen Feb 18 at 10:00

• @OMAR When using the ping operator, @, use TAB to cycle between the names and make sure that there are no spaces. "a concerned citizen" should appear "aconcernedcitizen". Otherwise there are no notifications. – a concerned citizen Feb 18 at 22:10
