- 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.

- Lastminderung (derating) Auch: Unterlastung. Das Anpassen eines Betriebsparameters an extreme Betriebsbedingungen, zum Beispiel das Begrenzen der Leistungsaufnahme ab Erreichen einer bestimmten Umgebungstemperatur. Elektroniknet - by John Jory
- Example sentence(s)
- Damit die Eigentemperatur (Summe aus Umgebungstemperatur und verlustleistungsbedingter Obertemperatur) die Grenztemperatur nicht überschreitet, muss ab einer Umgebungstemperatur von 70 °C die Verlustleistung entsprechend reduziert werden. Diese notwendige Verlustleistungsreduzierung wird auch als ..Derating" bezeichnet. Sie wird in den Datenblättern in Form einer Deratingkurve angegeben. - Google books
