This article deals with the gases dissolved in oil generated during the power transformer operation. The attention is paid to the production of gases typical for particular failures. The most powerful and widely used diagnostic tool for investigation faults and their root causes is dissolved gas-in-oil analysis DGA. Hydran sensor is one of the most used sensors applied for on-line monitoring of gas generation. The aim of this contribution is to compare the results and plausibility of the mentioned gas detection methods in medium-term period.
