IEC guide to the interpretation of dissolved and free gases analysis-mineral oil-impregnated electrical equipment in service. IEEE guide for the interpretation of gases generated in oil-immersed transformers. Suleiman, Asset management through effective transformer diagnostics & condition monitoring, in IEEE International Conference on Power and Energy (PECon) (Kota Kinabalu Sabah, Malaysia, Dec 2012), pp. The result obtained from the new DGA interpretation scheme showed promising results compared to the conventional Duval triangle. The gases produced during the deterioration of transformer oil and insulation paper have been examined using Duval triangle and the new DGA interpretation scheme, on the DGA samples collected from TIFAC-CORE Laboratory, NIT Hamirpur, and published papers. The paper presents a new DGA interpretation scheme carried out through several case studies using gas ratios and their proportion limit as rules implemented in MATLAB to diagnose the fault.
However, due to ignorance of the two combustible gases, namely ethane (C 2H 6) and hydrogen (H 2), this technique employs lower accuracy for certain faults type. Among all the techniques, Duval triangle is the most prominent. The most efficient and easy way of condition evaluation of transformer is by evaluating the concentration of gases present in the transformer oil, done using dissolved gas analysis (DGA) over which several techniques are employed to predict the type of fault present in the transformer. so far no so good tried, I am sure doing something wrong.Fault diagnosis of power transformer for condition evaluation is being carried out by oil analysis for decades. I have tried to build again the the moleculeLabel according to guidance lines. The creating of the duval pentagon process is like this: My current situation, is that I can created all the segments inside the pentagon,but I didn't figure out a way of placing labels of the gases around each corner(point) of my duval pentagon,any advice or help is welcome. Hey I have create a Duval Pentagon based on the post of creating duval triangle in canvas: how to create Duval Triangle in canvas.
