            • Derating can be defined as "the practice of limiting electrical, thermal and mechanical stress on parts, in a given design application, to levels that are below their specified ratings or their proven capabilities in order to enhance reliability". Reducing these stresses extends part life and usually, but not always (depending upon the nature of the part and the specific parameter involved) improves part reliability and hence system reliability. In addition, derating helps protect parts from unforeseen application anomalies and overstresses. Derating is a structured engineering approach to part application tailored to deal with, among other things, part variability. All parts do not have the same "strength." Part "strength" variability within any given population of parts is a fact of life and derating helps to compensate for this variability. Even parts from a so-called homogenous population, the same production line and from the same "production lot" exhibit some parameter variability. When so-called "interchangeable parts" are supplied by different manufacturers, possibly using different internal circuitry and different manufacturing processes, this parameter variability can be expected to become even greater. Derating helps to compensate for this type of "strength" variability. - İnternet by Salih YILDIRIM

            • declassamento
          • Additional fields of expertise
          • Definition(s)
            • Riduzione della capacità di generare potenza utile di una macchina rispetto alla potenza nominale, dovuta al discostarsi delle condizioni operative dalle condizioni di riferimento (o nominali). Esempi di fattori che influenzano maggiormente il declassamento di una macchina: variazione della temperatura, pressione, umidità del fluido di servizio o del fluido di scambio termico, esercizio della macchina in funzionamento diverso da quello di progetto (continuo, intermittente, con parametri elettrici non nominali, etc). Nei testi specialistici si può trovare anche non tradotto. Own research - by pcs_MCIL

            • POTENZA E DECLASSAMENTO Il valore di potenza indicato e' il massimo disponibile durante una sequenza di potenza variabile (PRP Prime Power) ISO Standard 8528.1 ed e' garantito con una tolleranza di + / - 5% , a motore rodato. Questo valore si riduce del: * 1% ogni 100 Mt. di altitudine * del 2% ogni 5°C al di sopra dei 20°C * del 10% per un utilizzo continuativo a carico costante (COP Continuous Power) ISO Standard 8528.1. - WFM generators by pcs_MCIL
            • Problemi di altra natura possono insorgere invece quando il gruppo elettrogeno viene utilizzato in ambienti dove i valori di temperatura, altitudine e umidità relativa sono più alti rispetto a quelli di riferimento. È questa una condizione spesso sottovalutata. La presenza delle suddette condizioni ambientali comporta un declassamento della massima potenza erogabile dalla macchina, tanto più accentuato, quanto più i valori si scostano da quelli di riferimento.

            • Per quanto riguarda il derating o in italiano "declassamento", le norme impongono per la classe B, ad una temperatura ambiente max. di 40°, una temperatura max degli avvolgimenti di 110°, mentre per la classe F, 145°. - PLC forum by pcs_MCIL

          • Additional fields of expertise
          • Definition(s)
            • "Ha elegendõ a rendelkezésre álló tápfeszültség, a forgórészfluxus megtartja állandó értékét a névleges fordulatszám eléréséig. A névleges fordulatszám felett a kapocsfeszültség az isx csökkentésével tartható állandó értéken. A fluxus nagyságát a PI-szabályozó pontos szinten tartja a hibajelbemenet értékének felhasználásával, amelyet a maximális megengedett motorfeszültségbõl és kapocsfeszültségbõl számít ki. A feszültségszabályozó kimenete úgy van korlátozva, hogy a maximális mágnesezõ áram a névleges mágnesezõ áram, a minimumérték pedig úgy, hogy a ###v kielégítse a maximális nyomaték feltételét."

          • Example sentence(s)
            • "1-2 éves megtérülési idővel számolhat olyan felhasználások esetén, mint pl. AHU ventilátorok, szekunder hűtöttvízrendszer szivattyúk, kondenzátorventilátorok (az energiaköltségek, a leterheltség, a motorteljesítmény és az üzemidő függvényében). Hogyan érvényesül ez az elv? A motor sebességét a névleges érték 80%-ára csökkentve, a nyomatékigény a névleges érték mindössze körülbelül 64%-ára csökken. Ez azt jelenti, hogy a motor sebességét a maximális érték 80%-ára csökkentve az energiafogyasztás a névleges értéknek mintegy felére csökken. - VarioTrane by Katalin Szilárd
