Abstract


This article will reduce the number of mistakes in interpretations of the results of gas concentrations analysis in the Buchholz relay gas and will improve the accuracy of the detected damage characteristics. The article helps to clarify the permissible values of the Buchholz relay gas concentrations and reveal the most informative diagnostic criteria. Information for this article was going to more than 20 years, since the operation of the gas transformer protection is rare.
