Nazivna kratkostična zmogljivost
Nazivna kratkostična zmogljivost predstavlja največjo vrednost kratkostičnega toka, ki ga lahko odklopnik ali varovalka prekine. Vsaka zaščitna naprava je zasnovana za določeno nazivno moč in s tem tudi za določen nazivni (obremenitveni) tok. Kratkostični tokovi lahko trajno poškodujejo zaščitne naprave zaradi prekomernega segrevanja in sproščene energije. V elektroenergetiki uporabljamo različne vrste električne opreme (zaščitnih naprav) z različnimi tehničnimi lastnostmi, ki vključujejo tudi kratkostično zmogljivost. Poglejmo nekaj primerov.
Rated short-circuit breaking capacity
Rated short-circuit breaking capacity represents the highest value of short-circuit current that a circuit breaker or fuse is capable of interrupting. Each protective device is designed for a specific rated power and therefore for a specific rated (load) current. Short-circuit currents can permanently damage protective devices due to excessive heat and the energy released. In electrical power engineering, we use various types of electrical equipment (protective devices) with different technical specifications that also describe short-circuit capacity. Let us look at some examples.
