Methods have been developed to interpret DGA results. Among them are the Key Gas, Rogers Ratio, Logarithmic Nomo graph, Dorenenburg, IEC Ratio and Duval Triangle. This paper uses the DGA data from different cases to test the accuracy and consistency of these methods in interpreting the transformer condition. It also describes the structure and specific features of transformer insulation ageing diagnosis based on artificial neural networks. MATLAB programs using neural network were developed to automate. Also this paper present three fault type, partial discharges (PD), discharges, thermal.
Oct 20, 2010 It is a software that written by me for DGA which uses of Duval Triangle method. There are some figures for results of the software. Figures above show. SoftwareMegger Equipment Support; SoftwareTest Data Management. The Duval Triangle method is described in the IEC Standard and in. Quite Imposing Plus Mac Serial. The results from the new developed Duval Triangle software will be compared. The creation of duval triangle by software implementation for dissolved gas analysis. Introduction to Duval's Diagnostic Triangles Presented. Invented the original Duval Triangle for transformer DGA, which was included in IEC.
