This paper presents an application on the analysis of gases dissolved in mineral insulating oil of power transformers, the Duval Triangle method. Through simulations yielded the results of incipient failures in transformers. So as pie charts of percentages of gases analyzed by the method. The expectation of this tool is to make it popular and free.
