Název v původním jazyce

Determination of cause for increased failure rate of electrical components

Popis výsledku v původním jazyce

Lifetime of components can be described with several distributions. Most frequently are used exponential, Weibull and gamma distributions. Exponential distribution is used for description of components which are in normal-life period and are not permanently strained.Weib. dist. is used for description of permanently strained components and components in the end-of-life period. The aim of this work is to set down reliability parameters of electric components on practical exampleand also to set down whether increased failure rate of components from the sample is random or is possible to make out their degradation.Total of about 14 000 components of several types were installed in the company during the years 2003-2005. Primary diversity was in the colourof LEDdiode and in the type of supply. The number of failures of components was not constant and it was necessary to prove whether increased failure rate is random or whether the component is degrading.
