- Definition(s)
- Derating is the technique employed in power electrical and electronic devices wherein the devices are operated at less than their rated maximum power dissipation taking into consideration the case/body temperature, ambient temperature and the type of cooling mechanism used.

- Example sentence(s)
- οι ηλεκτρονικές συσκευές έχουν μέγιστη απόδοση σε κάποια θερμοκρασία. Όσο η θερμοκρασία αυξάνεται η απόδοση ελαττώνεται δηλαδή η ικανότητά τους υποβιβάζεται π.χ. αν ένα εξάρτημα έχει 100watt απόδοση στούς 25C στούς 65C θα έχει 40watts απόδοση. - wikipedia

- Definition(s)
- Ev aletlerinin kapasitelerinin düşürülmesi bir taraftan dünya çapındaki enerji gereksinimini azaltırken, diğer taraftan sera gazı salınımının düşürülmesi suretiyle de gelecek nesillere daha yaşanabilir bir çevreninin islah edilmesine önemli ölçüde sürekli katkı yapılması sağlanmış olur. Own research - by Salih YILDIRIM
- Example sentence(s)
- 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.

- 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
- Example sentence(s)
- 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. In - rivista Attualità Elettrotecnica
by pcs_MCIL - 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
