Evaluation Of Reliability Indicators Of A Transformer Angular Displacement Transducer, S.F. Amirov, M.S. Yakubov, N.R. Yuldashev

The Scientific Journal of Vehicles and Roads

Based on the analysis of statistical data on the state of transformer angular displacement transducers, the following calculations of probabilistic reliability indicators were performed: failure rate, mean time to failure; the probability of failure-free operation with a sufficiently long operation and gamma-percentage resource; confidence upper and lower bounds are determined, under the chosen conditions of significance, the calculated values ​​satisfy Pearson's χ^2 criterion and therefore do not contradict the experimental data. By analyzing the selected levels of significance, the existence of exponential and normal laws in the laws of probability distribution was revealed.
