    Diagnostics of solid insulation of transformers by information assessment of indirect indicators

    Authors: M. S. Yakubov, K. H. Turdibekov, A. K. Sulliev /
    A mathematical model for diagnosing the state of solid insulation of high-voltage transformers based on an informational assessment of indirect indicators, i.e. entropy, for example, by the content of impurities of various gases dissolved in transformer oil, which allows to determine the technical condition without removing the workload. The values of the average information on the working and faulty state of insulation for various types of gas impurities are calculated.
