Bayesian Duval Triangle Method for Fault Prediction and Assessment of Oil Immersed Transformers [PDF]
Measurement + Control, 2017 Dissolved gas analysis of transformer insulating oil is considered the best indicator of a transformer’s overall condition and is most widely used. In this study, a Bayesian network was developed to predict failures of electrical transformers.

Analysis of Transformer Conditions using Triangle Duval Method
IOP Conference Series: Materials Science and Engineering, 2018 Abstract Electrical or thermal failure that occurred in the transformer oil can produce a dangerous gas called gas fault. By indicating the content of dissolved gases in the transformer oil, can be obtained information about what happened to the oil so it can be estimated indication of the type and cause of the failure in the transformer.

Diagnosis of OLTC via Duval Triangle Method and Dynamic Current Measurement
Procedia Engineering, 2013 AbstractPower 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 insulation degradation and contacts failure inside it. Other than that, contacts wear influences the OLTC performance and this phenomenon has not been deeply investigated.
