Interactive Duval Triangle Diagram
Visualize dissolved gas analysis results on an interactive Duval Triangle diagram to support transformer fault identification and analysis.
A web-based utility for dissolved gas analysis of oil-filled high-voltage transformers and other electrical apparatus, providing Duval Triangle diagrams and color-coded fault zones for further analysis.

The Duval Triangle diagram is used for fault type identification in dissolved gas analysis of oil-filled high-voltage transformers and other electrical apparatus.
Our custom utility provides an option to select the oil type and display the related Duval Triangle diagram for further analysis. This allows users to work with the appropriate diagram based on the selected oil type.
Fault zones are highlighted with different colors, making it easier to locate the affected fault zone after analysis and simplifying the interpretation of the analyzed results.
See how the Duval Triangle utility simplifies dissolved gas analysis by visualizing transformer fault zones and supporting faster, clearer diagnostic analysis.
Built for engineers who require accurate transformer diagnostics, interactive visualization, and a streamlined analysis workflow.
