Term (EN) | positive (sequence) component (of a three-phase system) |
Definition (EN) | One of the three symmetrical sequence components which
exists in symmetrical and unsymme-trical three-phase
system(s) of sinusoidal quantities and which is defined by
the following complex mathematical expression:
X1 = 1/3 (XL1 + aXL2 + a2 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. |

Term (BS) | komponenta direktnog redoslijeda (trofaznog sistema) |
Definition (BS) | Jedna od tri simetrične komponente sinusoidalnih
veličina koja postoji u simetričnom i nesimetričnom
trofaznom sistemu (sistemima) i definirana je
slijedećim kompleksnim matematičkim izrazom:
X1 = 1/3 (XL1 + aXL2 + a2 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. |
