Correlates all 8 fault gases, moisture-in-oil, oil temperature, and ambient temperature to transformer load.It also describes the structure and specific features of. This paper uses the DGA data from different cases to test the accuracy and consistency of these methods in interpreting the transformer condition. Among them are the Key Gas, Rogers Ratio, Logarithmic Nomo graph, Dorenenburg, IEC Ratio and Duval Triangle. This paper presents modification of Duval triangle DGA diagnostic graph to numerical method. When the mineral oil is subjected to high thermal or/and electrical stresses, it decomposes and, as a result, gases are generated. Dependable technique for the detection of incipient fault condition within oil-immersed transformers. Results of duval triangle software: Free download software, Free Video dowloads, Free Music downloads, Free Movie downloads, Games. With TM8 you can simultaneously track DGA, moisture, temperature and load on you transformer. The TM8 will provide a laboratory quality set of DGA results every 4 hours and up to once per hour under active fault conditions. Unprecedented accuracy and repeatability make the TM8 the perfect solution for monitoring mission critical applications where compromise is not allowed. Based on an analytical platform built around a Gas Chromatogram (GC) the TM8 takes the recognized laboratory technology onto your transformer. The TM8 is our industry leading 8 gas online DGA monitor.
