What is derating?, Why it is necessary, it is same for all means for drives, motors,and cables.
Answer / quratulain javaid
Derating is design process that can make significant contribution to reliability.The reliability of electrical/electronic component decrease when they operate at high stress level.These stresses are primarily temperature, voltage, current & power dissipation
In electrical derating means lowering the electrical capabilityof electrical apparatus'.In electronics derating is a operation of a device at less than its rated maximum power in order to prolong life.So it is necessary to know the derating factor for each component type related to one critical condition to run/operate in safe level.
