A brief review on the interpretation of DGA in transformers is presented, with a special emphasis on the Duval Triangle method. It is shown how the accuracy of . The Diagnostics accuracy of the ANFIS is much more accurate than ANN system. The faults are identified for the records using Duval triangle analysis which is. Various methods have been developed to interpret DGA results such as IEC ratio code, Rogers method and Duval triangle method. One of the most frequently.
invented the original Duval Triangle for transformer DGA, which was included in IEC Duval published the triangles in IEEE Electrical Insulation.

Power transformers studies have shown that the main cause of power transformers failures is the On Load Tap Changer (OLTC). OLTC failure occurs due to the. The general type of fault (PD, D1, D2, T1, T2, T3) can be identified by several methods: e.g.,. Rogers, Key Gas, IEC ratios, Duval Triangle 1. It is more difficult.
