| Term (EN) | negative (sequence) component (of a three-phase 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:
X2 = 1/3 (XL1 + a2XL2 + a XL3 )
where a is the 120 degree operator, and XL1 , XL2 and XL3
are the complex expressions of the phase quantities
concerned, and where X denotes the system current or
voltage phasors. |

| Definition (BS) | Jedna od tri simetrične komponente sinusoidalnih
veličina koja postoji samo u nesimetričnom trofaznom
sistemu i definirana je slijedećim kompleksnim
matematičkim izrazom:
X2 = 1/3 (XL1 + a2XL2 + a XL3 )
gdje je a operator rotacije od 1200, a XL1 , XL2 i XL3 su
kompleksni izrazi faznih veličina na koje se odnose,
a X znači fazore struje ili napona sistema. |
