CE ÎNSEAMNĂ INRUSH ÎN ENGLEZĂ?
Porneste curentul
Curentul de pornire, curentul de curent de intrare sau intensitatea de pornire se referă la curentul maxim de intrare instantaneu atras de un dispozitiv electric când este pornit pentru prima oară. De exemplu, becurile cu incandescență au curenți mari de aprindere până când filamentele lor se încălzesc și rezistența lor crește. Motoarele electrice și transformatoarele cu curent alternativ pot trage de câteva ori curentul lor normal de sarcină maximă când sunt alimentate pentru prima oară, pentru câteva cicluri de undă de intrare. Convertoarele de putere au adesea curenți de pornire mult mai mari decât curenții lor de staționare, datorită curentului de încărcare al capacității de intrare. Selectarea dispozitivelor de protecție la supracurent, cum ar fi siguranțele și întrerupătoarele de circuit, este complicată atunci când trebuie să fie tolerate curenții mari de aprindere. Protecția la supracurent trebuie să reacționeze rapid la supraîncărcare sau la scurtcircuit, dar nu trebuie să întrerupă circuitul atunci când curge curentul de pornire.

As explained in Chapter 2, when a transformer is switched on, the magnitude of
its inrush current depends on many factors, the predominant factors being the
instant of switching and the residual magnetism in the core. The inrush current

This is an often misunderstood topic. When energised, a transformer draws an
inrush current. Therefore, when a generator is connected to a system containing
transformers, the transformers will try to draw an inrush current from the generator
