| Description
| - Common values used for reliability calculations in Czech Republic are based on exponential distribution of failure rates. Disadvantage of this approach is that failure probability (hazard function) is constant. Virtually all components wear-out, their reliability decreases with time. This paper intend to describe Weibull probability distribution function of Time-to-Failure (and failure rate), which in principle includes component's wear-out. Further (and mainly) we deal with calculations of Weibull parameters form failure database for power lines (both overhead and cables) and switching gear. Calculation was done on failure databases from almost all Czech electricity distribution companies and some Slovak ones. Gained values can be used e.g. for reliability calculations using MonteCarlo simulation method. Also database history is briefly described in this paper

- Běžné hodnoty požívané pro spolehlivostní výpočty v České republice vycházejí z exponenciálního rozložení intenzit poruch. Nevýhodou tohoto přístupu je, že intenzita poruch (hazardní funkce) je konstantní. Ve skutečnosti všechny prvky se opotřebovávají, jejich intenzita poruch je neklesající. Tento článek popisuje Weibullovu pravděpodobnostní distribuční funkci času do poruchy, která ve své podstatě zahrnuje opotřebení prvků. Dále (a to především) se zabýváme výpočtem parametrů Weibullova rozdělení z databáze poruch energetických vedení (venkovních i kabelových) a spínacích prvků. Výpočet byl proveden na databázi poruch z let 2000-2004 získané z téměř všech českých REASů a jednoho slovenského. Získané hodnoty mohou být použity např. pro spolehlivostní výpočty pomocí metody MonteCarlo. (cs)
