The most important aspect of fault gas analysis is taking the ppm data that has been generated and correctly diagnosing the fault that is generating these detected gases. DGA Expert Systems software consists of a flexible and user friendly EXCEL file. The software can be used as a stand alone module to generate Dissolved Gas Analysis interpretative reports or used in conjuction with chromatography software via external data import.

INTERPRETATIVE METHODS Diagnostic reports generated utilizing DGA Expert Systems software include industry accepted methods and standards. Three interpretative methods are utilized : Key Gas Method Useful if no measured previous dissolved gas history is available. The data is compared to the majority of transformers. Users can establish custom flag limits on our reporting software. Rogers’ Ratio The advantages to any ratio method are that they are quantitative and independent of transformer oil volume. However, ratio methods can produce incorrect interpretations or none at all. Therefore they should be used in conjunction with other diagnostic methods such as the Key Gas Method. Additionally minimum levels of gases must be present before results of the ratio methods become significant. IEEE/ANSI C57.104 Guideline The guideline interprets the results in terms of transformer serviceability. The guidelines provide a testing schedule, recommends subsequent physical inspection or action, and protocols based on the fault gas generation rate.
