Fault Diagnostics in Oil Filled Electrical Equipment: Review of Duval Triangle and Possibility of Alternatives

2016 IEEE Electrical Insulation Conference (EIC), 2016
Fault diagnostics, identification and location in oil filled electrical equipment has been a challenging task which has been under critical focus of scientists in decades. One of the most successful methods of fault diagnostics and identification in such electrical equipment is the Duval triangle, which uses 3 fault gases; methane, ethylene and ...

Analysis of 132kV/33kV 15MVA Power Transformer Dissolved Gas Using Transport-X Kelman Kit Through Duval's Triangle and Roger's Ratio Prediction

2018 IEEE International Conference on Industrial Technology (ICIT), 2018
In this article dissolved gas in 132kV/33kV 15MVA power transformer is analyzed using the Kelman Kit (Transport-X) through Duval's triangle method and Roger's Ratio method. Under the impact of electrical, thermal and environmental stresses, the equality of mineral insulation oil deteriorates in a gradual manner, electrical failures such as hot spots ...

Development of an Application Based on the Duval Triangle Method

IEEE Latin America Transactions, 2017
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.

Transformer Fault Diagnosis with the Duval Triangle and Heuristic Techniques

Applied Mechanics and Materials, 2014
Dissolved gas analysis (DGA) is an effective tool for detecting incipient faults in power transformers. The ANSI/IEEE C57.104 standards, the most popular guides for the interpretation of gases generated in oil-immersed transformers, and the IEC-Duval triangle method are integrated to develop the proposed power transformer fault diagnosis method.
