In the article the reliability calculations of automatic transformers with adjustable range are performed. Since reliability is one of the main characteristics of current transformers, several parameters of its range are included in the calculation of the reliability of an automatic adjustable current transformer, and as a result, high-precision values of reliability were achieved.
