Term (EN)zero (sequence) component (of a threephase system)
Definition (EN)One of the three symmetrical sequence components which exists only in an unsymmetrical three-phase system of sinusoidal quantities and which is defined by the following complex mathematical expression: X0 = 1/3 (XL1 + XL2 + XL3 ) where XL1 , XL2 and XL3 are the complex expressions of the phase quantities concerned, and where X denotes the system current or voltage phasors.
