- Abstract
The dissolved gas analysis (DGA) is well established for early fault detection in liquid filled high voltage equipment. Various DGA interpretation methods already exist, which allow conclusions regarding an existing fault, based on the concentrations of the well-known typical fault gases and specific concentration ratios. Especially a significant increase in concentration of one or more fault gases as well as a noticeable increasing trend between different samples, taken at intervals, should be considered. The aim is to initiate suitable countermeasures at an early stage in order to maintain the longest possible lifetime with high reliability of the asset. This requires an enhanced reliability of the DGA interpretation. Thus, this paper presents the development, the setup and the first test of a prototype, which is able to detect not only the conventional fault gases but also higher C4 and C5 hydrocarbons. In first insulation liquid samples aged under laboratory conditions, the generation of different C4 and C5 hydrocarbons can generally be registered. Differences between the different insulation liquids are obvious.
