Please notice as the intersecting point touches a perticular area color the resulting fault will automatically appear at the bottom. The resulting plot for the given inputs are:

The color represents which type of fault is in the transformer.Īfter entering the values for CH4,C2H2,C2H4 the point of intersection will be location based upon the % contribution of the particular The screenshot for the Duval's triangle is: The intersection of those three points to finally draw out resulting dot on the duval's triangle. The Javascript file automatically map the concentration value to percentage and draw the coordinates on the triangle and finds The diagnosis will be done by taking the concentration values of for 3 key Gases CH4,C2H2,C2H4 and detect the fault in transformer. I have used canvas HTML5 to create and design the Duval's Triangle for this project. The data and ideas are taken from researach gate publication: It is a graphical method that allows one to follow the faults more easily and more precisely. One of the most frequently used DGA methods is Duval triangular.

Various methods have been developed to interpret DGA results such as IEC ratio code, Rogers method and Duval triangle method. Cosine law states that-a 2 b 2 + c 2-2 b c. (2017) integrate Duval triangle method and IEC ratio method together and apply fuzzy logic with the concept of energy weighing to evaluate the fault type and severity of the fault. Triangle calculator finds the values of remaining sides and angles by using Sine Law. Dissolved gas analysis (DGA) is one of the most useful techniques to detect incipient faults in oil-filled power transformers. Enter the values of any two angles and any one side of a triangle below which you want to solve for remaining angle and sides. It is of great importance for the utilities to find the incipient faults in these transformers as early as possible. Monitoring and diagnosis of electrical equipment, in particular power transformers, has attracted considerable attention for many years.
