English term

inrush current

GBK English to Serbian Tech/Engineering Electronics / Elect Eng
Definition from RTI Electronics, Inc.:
Inrush current is the initial surge of current that results when power is first applied to a load having a low starting impedance, such as a discharged capacitor, a cold lamp filament, or a stopped motor's winding.
Example sentences:
An NTC thermistor is always connected in series with the load to be protected. If the inrush current cannot be handled by one thermistor alone, two or more thermistor elements can be connected in series. (EPCOS AG)
Typical power converters made by other manufactures require the user to add external inrush current limiting components such as an NTC thermistor. In contrast, all BEAR converters have active inrush current limiting circuitry built into the module. (Bear Power Supplies)
The trips are caused by the initial start up current - or inrush current - which can be several times greater than their operating or steady-state current. In a three-phase motor, for example, inrush current generally lasts between 75-150 milliseconds with a current spike between 500% and 1200%. (Fluke Corporation)

udarna struja (uključenja)

Definition from Kyoritsu-instrumenti:
“Udarna struja”, - (ulazna udarna struja) je vršna trenutna ulazna struja obično uzrokovana pokretanjem (paljenjem) nekih električnih uređaja.<br /><br />Neka električna opterećenja, po pokretanju, trenutno primaju struju opterećenja, dok druga vuku početnu struju, koja može biti do 5 puta veća od normalne struje opterećenja Onda posle nekoliko ciklusa početna struja padne na vrednost stabilne struje opterećenja. Nekoliko primera sledi:<br />- Motori vuku vršnu struju pri pokretanju dok ne dostignu potrebnu brzinu. U suštini veći motori su obično zaštićeni mekim starterima (soft starters) za ograničavanje ovih efekata.<br />- Sijalice sa užarenom niti. Po paljenju, otpornost tanke žice (niti) je mala jer je još uvek hladna, rezultujući time veću struju. Postepeno tanka žica se zagreva i njena otpornost raste, rezultujući time niži i stabilniji tok struje.<br />- Aparati sa velikim kapacitivnim filtrima vuku udarnu struju dok se ne napune potrebnim elektricitetom.<br /><br />Udarna struja može loše delovati na električne komponente kao što su kola ispravljača i može uzrokovati prekidanje (okidanje) osigurača, topljenje osigurača, topljenje kontakata i prekidača napajanja. Takođe, ona utiče i na napon.
Example sentences:
Udarne struje uključenja transformatora su dostizale i do šestostruke vrednosti amplitudne njihove naznačene struje. (Elektrotehnički institut "Nikola Tesla")
Udarna struja uključenja zavisi od vrednosti reaktanse izvora napajanja i vrednosti reaktanse kondenzatora. Interesantan je i zaključak, da je vrednost udarne struje uključenja 105 kondenzatora uvek manja od struje kratkog spoja (ISC,max), na istom mestu u mreži jer je... ( 28. savetovanje JUKO CIGRE)
Kolika je maksimalno dozvoljena udarna struja za relejni izlaz na DL06 AC jedinici? 5A max za 250VAC omsko opterećenje, 3A max za 250VAC induktivno opterećenje. (Uno-Lux Processing)
