Condition assessment of power transformer using gas detection methods

摘要

W artykule analizowano obecno?? gazu rozpuszczonego w oleju transformatora energetycznego oraz zale?no?? tego gazu od ró?nego rodzaju uszkodzeń. Analizowano ró?ne metody pomiarowe i do celów analizy wybrano czujnik Hydran.%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.
