| Abstract: | This paper analyses the uninterupted continous service time data of water turbine generator by mathematical statistic method and proves that the fault rate of gLnerator agrees withexponential distribution. Finally, the probability densitv function of fault rate and the reliabilityfunction for the investigated generator are obtained. These functions can be used to assess the op-erational reliability of generator. |
